The Eternal Feminine: Focused, Goal-Oriented, Practical, and Loving

April 30th, 2012 by Paula Derry

Visiting colleges became part of our repertoire of family trips back when my daughter was a senior in high school.   We visited many schools to get a sense of the range of possibilities that existed.   As was typical, Vassar offered a tour of the campus for groups of prospective students and their parents, led by tour-guides who were undergraduate students.  Vassar’s tour had one unique feature.  An original campus building, which dated to the post-civil war era, had an exceptionally wide hallway.  This, we were told, was because the all-woman student body needed to be able to walk back and forth repeatedly in the halls in their wide skirts, as part of a college program in physical fitness. Vassar, founded on the idea that the education of women should equal that of men, had a program of physical culture to offset criticisms that the school was endangering women’s health by educating them.

Sheila Rothman describes Vassar’s history in her book “Woman’s Proper Place,” published by Basic Books in 1978.  The common wisdom in the second half of the 19th century was that people have a limited amount of biological “vital energy.”  Rothman (p.24) quotes a contemporary physician:  ”Woman has a sum total of nervous force equivalent to a man’s” but the force is “distributed over a greater multiplicity of organs…The nervous force is therefore weakened in each organ…it is more sensitive, more liable to derangement.”  Menstruation and pregnancy were times of special danger, when the demands on her system were greater and the possibility of physical and mental disorder increased.  Menstruation was a time when women were irrational, even insane.  Caution, however, was always called for, as when intellectual activity or other exertion used up nervous energy.  Thus, when Vassar was founded, a program was put in place to overcome women’s predisposition to illness through a structured environment and programs of physical exercise.  Later, the Association of Collegiate Alumnae conducted a survey to provide research evidence as to whether female college graduates were normal.

Back in the Vassar of the present, our student tour guide wondered:  “How could anyone believe anything so silly?” It’s true that we no longer talk about a “vital force.”  Yet, broad generalizations about the nature of women and reproductive physiology continue to exist that have an air of plausibility, based today on a different scientific language, one of hormones, neurotransmitters, and other players.   Not very long ago, menopause was defined as an “estrogen deficiency disease” that had a uniquely powerful effect on health.  Heart disease was a disease of civilization for men and a disease of the ovaries for women.   The idea that the menstrual cycle destabilizes women’s minds, creating mood and intellectual changes, continues to exist.

One of my favorites is the idea that women are somehow receptive, loving, and self-denying because of their maternal role, which is somehow mediated by estrogen.  Thus menopause may be said to be a time that women regain the ability to focus more on themselves, liberated from a physiological preparedness for reproduction and its needs.   Pregnancy is a dreamy time when women are moody and unable to think clearly.

Sure, mothers are receptive, loving, self-denying, but they are also many other things.  I love being a mother.  My relationship with my daughter has been powerful, unique, and wonderful.  However, I know that a mother who is lost in a dreamy connectedness to her child or reflexively puts her child before herself can’t do everything she needs to do.   A mother is emotionally connected to her child but also must be an individual who perceives the child accurately, as a separate person, in terms of the child’s motivation and perspective, in order to provide both a sense of connection and the mirroring needed for a child’s emotional development.   Further, children misbehave, make mistakes, and must be taught all kinds of things; mothers must have clear-headed, pragmatic, problem-solving skills.

Menstrual Bonding, Birth Control Brouhaha, and other Weekend Links

March 10th, 2012 by Laura Wershler

Research by SMCR members Tomi-Ann Roberts and Nicki Dunnavan garnered a lot of attention this week. Stories showed up at Live Science – Why Why Women Should Bring Their Periods ‘Out of the Closet, popular ladyblog Jezebel – Your Period Is a Time for Deep Lady-Bonding, and the Daily Mail - Women, start talking about it. Period! Roberts and Dunnavan surveyed 340 religious and non-religious women about their experiences and attitudes about menstruation. As the Daily Mail reported: ”U.S. researchers say women across the world need to be more positive about menstruation – and that means talking about it in public.”

There’s been lots of public discussion about contraception, some might say too much!  The birth control/medical insurance coverage brouhaha hit a boiling point last week with Rush Limbaugh’s egregious comments about Sandra Fluke, and the heated debate rages still. Maureen J Andrade at OpenSalon writes that Birth Control Is Not a Women’s Issue: It’s a Human Right, while Asma T. Uddin and Ashley McGuire, blogging at the Washington Post, insist It’s about religious liberty, not birth control.  A group of crafters has come up with a  unique protest action: sending “interfering” male government members a knitted or crocheted uterus, vagina or cervix, while feministing.com has invited readers to Talk About Birth Control For REAL.

Back to women’s experience of menstruation,  Enith Morillo in Menses’ non-sense: Menstruation and the Muslim Woman’s “Red Tent” and Carolyn West in Menstruation – Celebration or Taboo?, explore different cultural menstrual traditions.

Coming Off The Pill: A Mind Map Guide

March 7th, 2012 by Laura Wershler

Everybody can use a good map to help them get to where they’re going. Why not women heading to the land of non-hormonal contraception?

In my post on January 11, 2012 I asked if coming off the pill was a growing trend. I proposed to write a series of posts about the issues associated with the decision to stop using hormonal birth control.  For the purposes of this discussion assume that “coming off the pill” refers to quitting any method of hormonal contraception including the pill, patch, ring, shot, implant or Mirena intrauterine system.

As I was preparing a list of possible topics, I realized that one way to represent the complexity of issues involved in this decision is with a mind map: “a diagram used to represent words, ideas, tasks, or other items linked to and arranged around a central key word or idea.” It also occurred to me that readers could then add to this schematic, filling in important points based on personal or professional experience. So I got out my colored markers, did a little brainstorming and came up with Coming Off the Pill: Mind Map 1.0. I invite readers to comment, offering additions under the key headings I’ve noted and suggesting other categories that should be included.  Could this become a talking, planning or process guide for women considering the transition to non-hormonal birth control methods?

If you’ve thought about or been through the experience of quitting hormonal contraception, or if you’ve helped others through the experience, please contribute to the development of Coming Off The Pill: Mind Map 2.0 by posting your comments and suggestions. (I’ve already thought about other headings I could have included.) Besides providing me with a guide for writing future posts, what other ways can you imagine this mind map might be used?

Sex Ed for Teens: Where’s the Mucus?

February 24th, 2012 by Laura Wershler

Guest Post by Lisa Leger

Teen girls are getting pregnant, in part, because they don’t understand their menstrual cycles. It’s time for sexual health educators to step up and teach girls the primary sign of fertility.

A recent report by The Centers for Disease Control and Prevention (CDC) on teen pregnancy in the U.S., based on a survey of close to 5,000 young mothers who got pregnant unintentionally, found that half of them had not used birth control.  When questioned further, a third of those said that they didn’t think they could get pregnant. Their reasoning ties in with previous research findings that girls who get pregnant in their teens have misconceptions about their menstrual cycles. They don’t seem to understand how ovulation works and are failing to correctly identify the fertile days in their monthly cycles.

My colleagues in sexual and reproductive health education should take notice. These findings reveal a knowledge gap in sex education: Teens don’t know about the easy-to-spot sign of fertility that precedes ovulation – cervical mucus secretions. Let’s fix it by adding one simple phrase to our sex ed classes: “When you have mucus, you can get pregnant.”

We would also need to explain the ovarian cycle, how estrogen promotes cervical mucus production, the role of mucus in sperm survival and how to check for it. This is arguably among the most useful information young women and men could receive before leaving high school.

If girls had this knowledge then I believe that at least some of them would more accurately identify fertile days in their cycles and at least some unintended pregnancies would be prevented. When a girl knows that mucus on the toilet tissue means she is fertile and able to get pregnant, she may be empowered to avoid intercourse, insist on a condom if she has sex, or know if she needs to seek out emergency contraception. Or she may decide to just hang out with her girl friends. I’m not saying that fertility awareness is a magic wand. Of course, many factors influence our decision-making. But teens are capable of making wise choices when they have accurate information on which to base them.

I’ve talked to many public health nurses throughout my 20-year career as a fertility awareness instructor. They usually quibble about the effectiveness of fertility awareness as a birth control method and seem reluctant to mention the existence of cervical mucus for fear that “a little bit of knowledge is a dangerous thing.” They worry that some students, if taught fertility awareness, might screw it up, thinking they were “safe” when they were not. But the CDC report tells us that garbled understanding about how ovulation works is doing more harm than good.

I hasten to reassure my public health colleagues that I am not proposing we teach teenagers natural birth control. What I’m proposing is the awareness part, that we correct this critical gap in teenagers’ knowledge by explaining that mucus is an obvious sign of fertility.

I won over my local sex educator to this idea by showing her the evidence-based Justisse Method of Fertility Awareness User’s Guide. She now teaches the meaning of mucus in her ovulation lessons.I predict her students will benefit. When they feel that slippery wetness when wiping, they will remember that it has something to do with being fertile. When they see clear, stretchy mucus on the tissue, they will know it’s a fertile day. It seems obvious that reducing confusion about the fertile phase would result in fewer unplanned pregnancies among girls who are currently confused about when they’re safe and when they’re fertile.

Instead of withholding useful information about what cervical mucus means, let’s tell teens that avoiding sex when they observe mucus can prevent pregnancy.

Menopause Tales

February 6th, 2012 by Paula Derry

The philosopher of science Mary Midgley (1995) doesn’t mince words.  She tells us:  “The theory of evolution is not just an inert piece of theoretical science.  It is, and cannot help being, also a powerful folk-tale about human origins.”  Along these lines, stories about reproductive physiology are important folk-tales about what’s natural for women and what their life course should be.

What are the stories about menopause?  One is that living beyond menopause is a biological puzzle. The argument goes like this: Most animals reproduce up until, or close to, the end of their natural life span.  This makes sense, because theoretical biology tells us that animals reproduce as much as possible to leave as many offspring as they can.   Why women live beyond menopause is therefore a puzzle.  One answer is that we can expect to live thirty years past menopause because technological innovations have resulted in the conquest of infectious disease, the generation of great food stores, and other advances. As recently as the turn of the century, the average woman lived 47 years.  Far longer, probably, than our prehistoric forebears:  prehistoric hunter-gatherers were probably old at thirty.  Living many years past menopause is therefore a recent historical development.  Not surprisingly, if aging women are “outliving their ovaries,” menopause is associated with a variety of unpleasant experiences and health problems.

What are some facts relevant to this story?  First, is living past menopause a new historical development?  Well, ….No.  Old age is not an invention of the twentieth century.  Betsy Ross died when she was eighty-four.  Classic Greek and Roman medical writers (including Hippocrates himself) and traditional Eastern medical systems all discuss menopause. In the Old Testament, Sarah laughed when God said she would bear a child even though it had “ceased to be with her after the manner of women.”  Might the Bible have been referring to menopause?

What about the idea that prehistoric humans died before menopause? Studies by anthropologists suggest that modern hunter-gatherers do live to old age.  Therefore, perhaps our prehistoric hunter-gatherer forebears did so as well.  Richard Lee (1985), for example, studied the !Kung San in Botswana.  About 10% of the population were over sixty years old, and it was not unusual to find !Kung aged 70 or 80.   Lancaster and King (1985) found, when twenty-four hunter-gatherer and horticulturalist groups were examined, that 53% of the women who lived to age fifteen could expect to still be alive at age 45.

If a small number of older people are found in simpler societies, is this important?   Is ten percent survival so small that for all intents and purposes fifty years is the real limit on lifespan?  Older people, as described by anthropologists, are not viewed by the members of their own societies as oddities.  That is, if living into middle-age and beyond were an anomaly, it is unlikely that people in a society would have expectations about what role an older person should play.  Older people might be viewed as curiosities.  However, older people more typically have important places in their societies.  At least through their fifties and sixties, they are relied on to do important things.  It is relatively common in nonindustrial societies for women to experience positive changes in status when they become middle-aged (Brown, 1985).  In cultures without written legal systems or CEOs, older people often have authority over younger people.  They can be decision-makers about the distribution of property, allocation of jobs, and other social behaviors.  Among the !Kung, for example, older women assign younger relatives what jobs they need to do, arrange marriages, decide on kinship classifications.  In cultures that don’t have books or the internet, older people may be sources of stored and accumulated knowledge, like the location of a watering hole that hasn’t been needed since the last drought thirty years ago (Diamond, 1996), or social and technical skills (Kaplan et al., 2010).

Do You Trust Women?

January 23rd, 2012 by Chris Bobel

Do you see the connections between menstrual health awareness and reproductive justice?

At re: Cycling, we sure do, because being critical of how menstruation is regarded (and managed)—from menarche forward—is one way we loosen the social control of women’s bodies.

My body, my choice, my whole life long.

And that’s exactly what reproductive justice is about—fighting for everyone’s access to affordable, quality reproductive health care of their choosing. That’s a fight to get behind, not the stupid “War on Women” advanced by certain presidential hopefuls (Hello Rick Santorum).

We are excited about this creative campaign organized by The Trust Women/Silver Ribbon Campaign, a coalition of 42 national and local organizations (the Bay Area Coalition for Our Reproductive Rights (BACORR), Catholics for Choice, NARAL-ProChoice California, Planned Parenthood Shasta Pacific, and SisterSong/Trust Black Women.

The campaign takes aim at “extremist politicians elected with a mandate to fix the current economic crisis instead chose to divert the public’s attention with policy battles about these private decisions.”

So why are our legislators and presidential candidates hell-bent on denying access to basic health care services –including contraception and abortion?

Really, why do we let them get away with this?

In San Francisco, The Trust Women/ Silver Ribbon campaign is literally taking the message of reproductive justice to the streets by flying banners—colorful, clear and decisive—all over the city. The banners are more than a defensive operation in the battle against women’s autonomy; they seek to end the offensive by reminding us that most Americans are, after all, pro-choice.

The banners read:

  • Her Decision, Her Health
  • U.S. Out of My Uterus
  • Fix the Economy, Support My Autonomy
  • Reproductive Rights are Human Rights
  • San Francisco is Pro-Choice

That’s all very good, you might say, but I don’t live in San Francisco.

During Trust Women Week, January 20-27, the campaign is staging a Virtual March (with  MoveOn)—a time for reproductive justice supporters to express their support online.

So go here and take action.  Let’s end the War on Women.

How do YOU define reproductive health?

December 8th, 2011 by Heather Dillaway

By Justine Siegemundin, 1723. Public Domain, via Wikimedia Commons.

Menstruation and menopause are reproductive health experiences, aren’t they? At least that’s what I think. But I’m starting to wonder how many people agree. I’ve been thinking a lot lately about how people define the things they experience and how researchers define the things they research. The last blog entry I wrote was on the confusing and frustrating definitions of the menopause transition. Today I thought I’d zoom out a bit more and think about what “reproduction” and/or “reproductive health” means. I personally think of reproductive health as encompassing a woman’s entire life course and including a whole range of experiences (and the pursuit and achievement of individual wellbeing throughout all of these experiences) but I don’t know if others do. For instance, about two weeks ago I was on the phone with a potential coauthor, and she and I had a misunderstanding because I was talking about “reproductive health” as including prevention of HIV and other STDs and she was thinking of “reproductive health” as just about conception, pregnancy, and birth.  I’ve been studying what I think of as women’s normal reproductive processes and experiences (e.g., menopause, menstruation, pregnancy, childbirth, and breastfeeding) for a long time, so I thought I would use this blog entry to tell readers what I think about “reproductive health” and see if anyone agrees with me.

Adrienne Rich, in her 1986 edition of Of Woman Born, proposes that biological reproduction has been defined narrowly by most people (feminist or otherwise). Thus, for many, “reproduction” is equated with just two female processes: pregnancy and childbirth.  While it may not have been the goal of any one person to define reproduction so narrowly, this seems to be a reality.  At various points throughout history, conception and contraception – at times, even abortion – have been added to the definition of what “reproduction” meant, or what “reproductive rights” women were owed, but “reproduction” and “reproductive health” still refers to a very short list of experiences.

I believe we should acknowledge, however, that women’s “reproductive” experiences include more than just conception, contraception, pregnancy, and birth. Reproduction includes an entire range of reproductive experiences, including: menstruation and menopause, use of and problems with contraceptives, choosing whether to become a mother/father, breastfeeding, HIV and other sexually-transmitted diseases/infections, prostate and breast cancer, awareness of and access to reproductive health care, protection against sterilization abuse, vasectomy and hysterectomy experiences, the rights of single and/or lesbian mothers, the rights of single and/or gay fathers, donor insemination, cloning and other new advancements in reproductive technology, adoption, infertility treatments and experiences, gynecological practices, alternative reproductive health movements, decisions over whether to engage in heterosexual intercourse, and making informed “choices” in any of these instances. This is just a partial list, and I could go on and on. I propose that we think of “reproduction” (and, by default, “reproductive health” experiences) as the collection of (a) biological, physiological and/or embodied processes and (b) emotional, social, economic, and political decisions and/or actions that individuals — along with their families and other social groups — participate in (either voluntarily or sometimes through some sort of coercion), as they transition in and out of certain stages of their life course, decide whether or not to be sexually-active, and/or decide whether or not to become genetic, gestational and/or social “parents” or caregivers of children.  Any one reproductive experience – for example, menstruation or menopause – can also really be a set of processes and decisions and actions that women make/take/experience/pass through over an indefinite period of time – usually not happening in just one moment. Thus, menstruation or menopause are full-fledged and complicated reproductive experiences in and of themselves, as much as pregnancy or childbirth or any other “reproductive” experiences are, that the majority of women pass through, albeit in different ways, throughout their lifetimes. So are all of the other processes and experiences I’ve named above, and more I haven’t named. “Reproductive health” would then refer to a state of physical and mental wellbeing, indeed biopsychosocial wellbeing, while experiencing any of these sets of processes or decisions or actions.

Teens Using the Rhythm Method? It’s Time for Body Literacy

June 8th, 2010 by Laura Wershler

Cycle SavvyTeen sex: More use rhythm method for birth control.

It was an odd headline for an Associated Press story on the 86 page report on teen sexual activity just released by the Centre for Disease Control and Prevention. Not all that relevant to the broader subject of the study on which the report is based: Teenagers in the United States: Sexual Activity, Contraceptive Use, and Childbearing, National Survey of Family Growth 2006-2008. If you’re interested, it is a fascinating read.

But it was the headline and this excerpt from the story that caught my attention:

About 17 percent of sexually experienced teen girls say they had used the rhythm method – timing their sex to avoid fertile days to prevent getting pregnant. That’s up from 11 percent in 2002.

They may have been using another form of birth control at the same time. But the increase is considered worrisome because the rhythm method doesn’t work about 25 percent of the time, said Joyce Abma, the report’s lead author. She’s a social scientist at the CDC’s National Center for Health Statistics.

You can’t study what you don’t understand. The study authors demonstrate their lack of knowledge about natural birth control methods by the question they asked study participants:  Have you ever used rhythm or safe period by calendar to prevent pregnancy?

There are many brands of natural birth control. Some , like the Rhythm and Calendar methods, are not effective. No proponent of Natural Family Planning (NFP) or Fertility Awareness Based Methods (FABM), which have effectiveness rates as high as 99.4 percent, would recommend them.  Yet this study does nothing to differentiate between these methods of natural birth control, thereby confusing the public, the study results and themselves.

It’s high time researchers studied up on natural birth control methods if they want to include questions about them in a study on the contraceptive practices of teens or adults.

Until they do, I suggest anyone interested in the sexual and reproductive health of teen girls start buying copies of Cycle Savvy: The Smart Teen’s Guide to the Mysteries of Her Body.  This book can help our daughters acquire the life skill of body literacy – to understand the mysteries of their menstrual cycles and how this knowledge can serve them well as they make decisions about their sexual and reproductive health and lives.

Book Review: In Our Control

May 21st, 2010 by Elizabeth Kissling

Laura Eldridge’s new book In Our Control: The Complete Guide to Contraceptive Choices for Women (Seven Stories Press, 2010) isn’t kidding with that subtitle. The last time I remember reading so much detail about contraceptive options was poring over Our Bodies, Ourselves when I was in my 20s.

Eldridge reviews every method of birth control known to modern woman–and, importantly, some that aren’t widely known. She even briefly reviews the history of contraception in 19th and 20th centuries, reminding us that birth control is not a new invention. People, especially female-bodied people, have struggled to control their fertility from pretty much the first moment humans figured out how it worked.

In Our Control differs from Our Bodies, Ourselves in offering more than just the mechanics of both hormonal and barrier methods: Eldridge provides a history of each method and analysis of the political and cultural contexts of their use in the 21st century U.S.

For example, the chapter about the morning-after pill (also known by either the brand name Plan B or as emergency contraception, EC) discusses the political battle to achieve Federal Drug Administration approval, including Susan Wood’s resignation from the FDA’s Office of Women’s Health over what she believed to be “willful disregard of scientific evidence showing Plan B to be safe.”

Eldridge extensively addresses the relationship between birth control and menstruation, focusing one chapter specifically on the use of hormonal contraception to reduce or eliminate menstrual cycles. She draws upon a wide range of resources to illustrate the cultural attitudes and contexts of menstruation, from stories of the role of birth-control pill co-developer John Rock’s Catholicism in the three-weeks-on/one-week-off dosing of the first pill to a Saturday Night Live parody of advertising schemes for menstrual suppression drugs (with Annuale, you’ll menstruate only once a year, but hold on to your fucking hat!).

The book also covers environmental impacts of contraception, the politics of HPV vaccinations, ongoing research into a birth control pill for men and natural methods of birth control such as fertility awareness–which Eldridge carefully distinguishes from the much-maligned “rhythm method.” She notes that the method approved by the Catholic church is properly called a calendar-based method and involves estimating when ovulation occurs and avoiding sex during that time. Fertility awareness, however, involves a more complex, systematic attention to physiological markers of female fertility. It requires careful monitoring of waking temperature, vaginal sensation, position of cervix and cervical fluid, as well as dates of menstrual flow and sexual activity. Eldridge cautions that fertility awareness is too complicated to be taught in a short chapter, and that observing and charting one’s cycle must be done “for a significant amount of time before you begin to rely on it for contraception.”

Laura Eldridge learned women’s health writing at the side of the late women’s health advocate and activist Barbara Seaman, and it shows. She contextualizes her work with her own experience and preferences, but provides thorough documentation so that women can more easily make their own decisions. This is women’s health activism at its best. Feminism isn’t just about choices, but about having access to information and resources to make informed, authentic choices–and that is only possible when reliable and comprehensive information is widely available.

Ultrasound Man:Birth Control Superhero

May 17th, 2010 by Laura Wershler

superheroYou know how most superheros become superheros because of exposure to some weird, intensified chemical or element? Take Peter Parker’s spider bite for example.

According to a story reported in various media, including International Planned Parenthood Federation’s website, if science can perfect the contraceptive effect of ultasound on men’s testicles, then we may be in for a new breed of superhero.  Ultrasound Man: able to bear the burden of pregnancy prevention for women everywhere. 

I joke, but for decades women have yearned for gender equality when it comes to bearing the burden of birth control. Could the promise of six months of ultrasound induced, reversible infertility in men be the answer? Well, to date, we only know it works in rats. There is a long way to go before we send the men for a bi-annual ultrasound “zap test”.

This isn’t the first male method touted over the last decade. In 2003, news out of the UK about a birth control pill for men had women nodding their heads with approval. I was immediately dubious and dashed off a commentary for the Calgary Herald that began thus:

Memo to Big Pharma: Save your money. If you think the male birth control pill is going to be a big seller, think again. Memo to women everywhere: Curb your enthusiasm. If you think it’s time men took more responsibility, you’re right — but the Pill for Bill is not going to be it.

Because of the complex hormonal action of the pill for men, I knew it wouldn’t fly. As I noted in my piece:

According to a story from the London Telegraph, because the treatment is invasive, it is likely to be used only by men in long-term relationships. Read it and weep, gals, because this is the wicked truth. It’s OK for women of any age or relationship status to ingest birth control pills or receive the Depo-Provera injection that completely shuts down their reproductive systems, but men would never do the same. It is already postulated that only men in committed relationships are likely to submit to invasive hormonal contraception. That would be supportive husbands and partners of the best kind.

Although a recent  survey by the Family Planning Association found that one third of men would definitely use a birth control pill for men if it became available, I doubt very much, once the mechanism of action were explained (full disclosure), that there would be many takers. I suspect the side effects, and concerns about synthetic testosterone, would result in a pathetic compliance rate.

Certainly the ultrasound method sounds much less invasive. Research leader James Tsuruta of the University of North Carolina said: “We think this could provide men with reliable, low-cost, non-hormonal contraception from a single round of treatment.

Happily, “the team plans to investigate the mechanism that causes temporary infertility.” I think the guys would want to know how and why it works before signing up.  But they can rest assured because Dr. Tsuruta also said: “Establishing safety, efficacy and reversability: these are our top concerns.”

As media stories proliferate documenting the growing trend among young women to eschew the Pill (et. al) in favour of non-hormonal methods, news that there may be a safe, simple method for men on the horizon is both welcome and long overdue.

What I find hard to take, however, is this suggestion expressed by Allan Pacey from the University of Sheffield:

There is certainly a place for an effective non-hormonal contraceptive in men, but whether men would find it acceptable to have their testicles scanned regularly remains to be seen.

Does your birth control method stop your cycle?

April 20th, 2010 by Chris Hitchcock

It’s starting. With the approaching 50th anniversary of the birth control pill, there will be a flood of anniversary celebrations and reviews of birth control methods. Which is good. We should have those discussions more often. Just say “no” (on the part of parents who don’t want to hear about it) is a big contributor to unwanted teen pregnancy.

Today’s Wall Street Journal is running an article called The Birth-Control Riddle. The riddle is apparently the high rate of unwanted pregnancy, despite the availability of a range of effective birth control methods. And, as befits the Wall Street Journal, each birth control method is accompanied by a price tag, so you can make an informed consumer decision.

But what I noticed was that there is no real awareness of what we at SMCR feel is an important consideration: Does your birth control method stop your cycle?

Some methods do – they deliver progestins and/or estradiol in high enough doses to act on the parts of the brain that normally make the hormones that talk to the ovaries that stimulate growth of a follicle, then trigger its release. This is a complex, whole body system, that normally we only notice because of uterine effects (that would be menstrual bleeding or pregnancy). And as a culture we have fairly casually accepted the idea that it is optional, and perhaps even optimally replaced by a pill made by a drug company.

When addressing the (no longer so) new extended use cycle-stopping contraceptive options, the WSJ glibly explains that “Experts say there is no health reason that women need to have a period if they are not ovulating or building up uterine lining each month.” In other words, so long as your uterus is not endangered (by pregnancy or endometrial cancer), there is no worry. Never mind that both estrogen and progesterone act on receptors throughout the body (bone, skin, blood vessels, brain, gut, breast), or that the synthetic estrogens and progestins don’t quite act in the same way, and we don’t quite completely understand how yet. And it’s just a change of schedule, so what difference can it make that your tissues are stimulated for 12 (or 52) weeks at a time instead of 3 before they get a break?

The problem is, with changes in the schedule of delivery and the reduction in hormone-free time, we really won’t know whether there are any consequences for a while. Oral contraceptives are taken by healthy young women, so the base rate of problems is low, and you need large numbers to measure the rates of serious side effects. I haven’t heard any further about the post-marketing surveillance studies for blood clots (venous thromboembolism) that the FDA asked Lybrel to conduct following its 2007 approval. But those 5-year followup data should be out around 2013. It will be interesting to see whether they are published, or just submitted as a report to the FDA. I’m guessing that will depend on whether the company likes the story they tell.

When new moms are sometimes forgetful or spacey, it is often attributed to ‘baby brain’ or ‘mumnesia’ or some other clever appellation that reinforces the idea that pregnancy leads to memory loss. It’s another variation on the women-are-ruled-by-hormones meme. In my humble opinion, the sleep deprivation that often accompanies late pregnancy and life with a newborn is a far more likely cause of memory loss.

While the research team at the Centre for Mental Health Research of the Australian National University didn’t investigate my theory, their research found no evidence that pregnancy or motherhood affects women’s brain power.

Professor Christensen’s team recruited 1,241 women aged 20-24 in 1999 and 2003 and asked them to perform a series of tasks. The women were followed up at four-year intervals and asked to perform the same cognitive tests. A total of 77 women were pregnant at the follow-up assessments, 188 had become mothers and 542 remained childless. The researchers found no significant differences in cognitive change for those women who were pregnant or new mothers during the assessments and those who were not.

The researchers suggest that previous findings that appear to confirm the ‘baby brain’ phenomenon are likely due to biased sampling. Their study, published in the British Journal of Psychiatry, was the first time women had been recruited from the general population before pregnancy.
