Are You Too Physically Fit for Motherhood?

September 2nd, 2010 by Elizabeth Kissling

Image of slender white woman doing bicep curls with small barbell.The headline of a story at ABC news about infertility among female athletes is “Female Athletes Are Too Fit To Get Pregnant“. Many women athletes in their 20s, at peak performance levels and peak physical fitness by most measures, may find themselves unable to conceive. This is attributed to low percentages of body fat, which essentially shut down the hypothalamus, which then fails to trigger the H-P-O (hypothalamus, pituitary, ovary) hormone sequence necessary for regular menstrual cycles. About 12% of infertile women seeking treatment are athletes.

According to the article, even women who are not professional athletes (or training at that level) can experience infertility due to physical fitness:

It noted that recreational jogging — only 12 to 18 miles a week — can result in poor follicular development, decreased estrogen and progesterone secretion and absent ovulation.

Setting aside the seriousness of infertility, I’m intrigued by the tone of the article, and especially the language of the headline. In North America today, there is a strong emphasis socially and in mass media on the importance of exercise and being physically fit, and corresponding demonization of fatness as a personal moral failing. But amenorrhea and infertility as a result of thinness is reported without judgment and body-shaming. There are no quotations from experts about women exercising too much or advice to stop working out; instead, professional athletes are advised to freeze their eggs in their early 20s. When fat* women have trouble conceiving or have difficult pregnancies, it is frequently attributed to their weight, which is presumed to be a behavioral a matter of choice.


*I am following the practice of other advocates of fat acceptance and Health At Every Size (HAES) in using the term fat as a descriptive adjective, not a pejorative.

Hold the Eggs When Ovulating

August 11th, 2010 by Elizabeth Kissling

Fascinating new research from the National Institutes of Health finds that women’s cholesterol levels correspond with cyclic changes in estrogen levels. Total cholesterol levels can vary by as much as 19% over the course of the cycle.

The researchers found that as the level of estrogen rises, high-density lipoprotein (HDL) cholesterol also rises, peaking at the time of ovulation.

In a typical cycle, estrogen levels steadily increase as the egg cell matures, peaking just before ovulation. Previous studies have shown that taking formulations which contain estrogen — oral contraceptives or menopausal hormone therapy — can affect cholesterol levels. However, the results of studies examining the effects of naturally occurring hormone levels on cholesterol have not been conclusive. According to the NIH’s National Heart, Lung and Blood Institute, high blood cholesterol levels raise the risk for heart disease.

. . . .


In contrast, total cholesterol and low-density lipoprotein (LDL) cholesterol levels — as well as another form of blood fat known as triglycerides — declined as estrogen levels rose. The decline was not immediate, beginning a couple of days after the estrogen peak at ovulation.

These findings provide another reason for girls and women to learn to track their cycles, so their blood tests can be interpreted more precisely.

It also gives more weight to the frequent assertion of members of the Society for Menstrual Cycle Research that menstruation matters — and is worthy of our study — in part because it is not an event isolated in the uterus and vagina, but a complex part of the endocrine system that has effects on health and well-being throughout a woman’s body.

Reproductive Coercion

July 29th, 2010 by Elizabeth Kissling

In our May 28 “Saturday Surfing” round-up of recommended reading, we highlighted Lynn Harris’ essay for The Nation about new research on “reproductive coercion”: the alarming frequency with which young men try to get their partners pregnant, often by sabotaging birth control methods. Yesterday, GritTV with Laura Flanders interviewed Harris and Elizabeth Miller, the researcher who conducted the study, about the phenomenon and public health responses.

Teens and the IUD

A new study published in the Journal of Obstetrics and Gynecology has found that adolescents are usually able to tolerate the Mirena® IUD rather well. The mean age of girls in this British study was 15.3 years, and they were prescribed the Mirena® for painful and/or heavy periods that did not respond to oral medications. 93.4% of girls in the study (45 young women) reported “significant improvement” within four months. The researchers conclude “that Mirena is a well tolerated and effective alternative for heavy periods±dysmenorrhoea in adolescents who do not respond to oral therapy.”


So will this finding make it easier for young women to obtain an IUD if they’d like it for birth control, now that there is evidence that it is well tolerated?

Should the pill be available over-the-counter?

June 25th, 2010 by Elizabeth Kissling

The New York Times published an op-ed piece a few days ago about making the birth control pill available without a prescription. Kelly Blanchard, president of Ibis Reproductive Health, offers the following rationale:

Women don’t need a doctor to tell them whether they need the pill — they know when they are sexually active and want to avoid pregnancy. Pill instructions are easy to follow: Take one each day. There’s no chance of becoming addicted. Taking too many will make you nauseated, but won’t endanger your life, in contrast to some over-the-counter drugs, like analgesics.

I have mixed feelings, myself. I’m in favor of just about anything that makes contraceptives more accessible to the people who need them, but I fear that the likely increase in cost of OTC pills means the availability won’t benefit those who most the need them – the young and the poor. Also, there are some contraindications for pill use, such as high blood pressure, history of migraine, and use of certain anti-seizure drugs for epilepsy. And despite the happy, shiny images of Yaz and Seasonique commercials, some women just can’t tolerate the side effects, for any number of reasons.

What do you think, re:Cycling readers?

The Disappearing Diaphragm

Did you know that last year’s combined sales of Yaz and Yasmin, the most popular oral contraceptives in the U.S., totaled $1.64 billion? Did you know the drugs are also the target of 1,100 lawsuits for potentially fatal blood clots? Did you know that an estimated 50 women have died from taking those contraceptives?

Despite such health risks,  however, oral contraceptives remain an extremely popular method of birth control in the U.S., second only to sterilization. The Guttmacher Institute reports that whether a woman prefers the Pill or sterilization is largely a function of age, with women under 30 choosing the Pill and women over 30 choosing permanent methods. These trends have been fairly stable since 1982.

None of these facts surprised me as much as the news that fewer than one percent of women in North America (and northwestern Europe) use the diaphragm–or any other woman-controlled barrier method. I’m puzzled that a safe, reliable, fairly easy-to-use (with some training and practice), inexpensive method of controlling fertility is not more widely recommended. Used correctly and consistently, the diaphragm has an effectiveness rate of 94 percent. Nevertheless, diaphragm use declined after the Pill was introduced, from 25 percent of married women in 1955 to 10 percent in 1965, and kept dropping thereafter, to just 4.5 percent of all women in 1982 and 0.2 percent today, according to the CDC [pdf].

Advanced Technology Isn’t Always Advanced Medicine

Panel from Sally Forth cartoon, "About my idea for robot monkeys...."A new report indicates that surgery for endometriosis performed by a robot is less effective than the same procedure performed by a surgeon. The mechanically assisted procedure also took longer to complete. Performing this surgery the traditional way can also help keep hospital costs down.

SMCR Bloggers Respond to ACOG’s Homage to the Pill

May 20th, 2010 by Laura Wershler

MenstruationResearch.org – Today, during an email exchange among the Society for Menstrual Cycle Research blogging team, research-advocacy experts on the menstrual cycle spoke out in response to the unbridled passion for the pill expressed by members of the American College of Obstetricians and Gynecologists at their 58th Annual Clinical Meeting. Amidst the hoopla surrounding the 50th anniversary of the pill, it must be noted that not all experts believe the pill to be an unequivocally positive contribution to women’s health and well-being that those quoted in the ACOG media release purport it to be.



“The pill has literally changed the world, and it was a primary stimulus to the women’s movement of the 60s. It has done far more for women’s rights than any legislation that has been passed and should be recognized as the great emancipator of women.”


Mark S. DeFrancesco, MD, MBA, Cheshire, CT
Secretary Elect, The American College of Obstetricians and Gynecologists

“When the pill first came out, young unmarried women had to fight for the right to take it. Now, they have to fight for the right NOT to take it. Overhyped as medicine’s gift to women’s health, by mostly male gynecologists who have never taken the drug, the pill has become an almost forced right of passage – the “standard of care” treatment for being a girl. Emancipation or subjugation? Ask the young women who face coercion and control by their doctors when they ask for support to use non-hormonal methods of birth control.”

Laura Wershler, Sexual Health and Reproductive Rights Advocate,
Executive Director, Sexual Health Access Alberta


“Birth control pills provide women with many non-contraceptive benefits, including cycle control, cancer prevention, and pain relief. They have been an integral part of women’s health.”

Scott D. Hayword, MD
Mt. Kisco, NY
Chair, District II, The American College of Obstetricians and Gynecologists

“Birth control pills provide women with many risks in exchange for contraception, including blood clots, stroke, breast, cervical, and liver cancers, diminished libido, and mood disorders. They have been instrumental in activating the women’s health movement, as feminists
demanded responses to these risks.”

Elizabeth Kissling, Ph.D.
President, Society for Menstrual Cycle Research


“I have often thought that the birth control pill should be called a hormone regulation pill because its use and impact have been so much broader than contraception alone. The pill has certainly improved reproductive control, but the impact on menstrual regulation has been very important for women, from adolescence to menopause.”


Jeanne A. Conry, MD, PhD
Roseville, CA
Chair, District IX, The American College of Obstetricians and Gynecologists

“I’m so happy to have The Pill called “a hormone regulation pill” because that is the way it is currently used by many physicians, and some women. It is used to cover up the far-apart cycles of anovulatory androgen excess (also known as PCOS) but doesn’t promote ovulation. The Pill is used to treat heavy bleeding in teenagers, but doesn’t restore her own balance of estrogen and progesterone. It is used for menstrual cramps when ibuprofen or other non-steroidal is more effective and has no suppressive effect. It is used to treat premenopausal osteoporosis when the evidence suggests it causes rather than prevents subsequent fragility fractures.

In short–the Pill has become the major non-surgical tool of gynecology.”

Jerilynn C. Prior, MD, FRCPC
Professor of Endocrinology / Department of Medicine
Centre for Menstrual Cycle and Ovulation Research
University of British Columbia

“The introduction and rapidly accepted, widespread adoption of oral contraceptives among women of reproductive age drastically reduced women’s fear of unplanned pregnancy in ways their mothers and grandmothers never knew. The pill has allowed women to take different roles in all aspects of their lives—career, education, travel, and a host of other beneficial ways.”

J. Craig Strafford, MD, MPH,
Gallipolis, OH
Vice President, The American College of Obstetricians and Gynecologists

“Women realize their full potential when they are supported in making informed decisions in all aspects of their lives. Indeed, oral contraception has enabled women to avoid unplanned pregnancies, but it has never been a risk-free option. While providers are eager to prescribe the pill, they are less eager to fully explain how hormonal contraception works and the side effects it carries. Until women have access to a full range of safe, affordable and accessible options, their freedom is compromised.”

Chris Bobel, Ph.D.
Chair and Associate Professor of Women’s Studies, University of Massachusetts-Boston

“The pill has revolutionized women’s health care. Obviously, the contraceptive benefits are paramount, but I have become a huge advocate for all of the non-contraceptive reproductive health benefits that the pill offers. Another advantage is that the pill has enjoyed incredible safety over its 50-year history.”

Douglas H. Kirkpatrick, MD, Denver, CO
Immediate Past President, The American College of Obstetricians and Gynecologists

“The Pill has its roots in a time much farther back than fifty years.
Historically the female body has been feared and the release of the
Pill fitted very easily into this history. Victorian doctors removed
women’s ovaries in response to many perceived female problems, and today doctors prescribe the Pill, shutting down ovulation. The Pill is not only prescribed for birth control – it is handed out to women with acne, PMS, irregular periods, heavy periods. Even light, regular periods are now considered enough of an inconvenience to warrant a long-term drug dependency. The Pill has developed into a medication for the disease of being female. In place of changing society, society decided to fix women. At a time when we are more concerned about what we eat, what we wear, what we use to clean the toilet than ever before, we are still celebrating millions of otherwise healthy women taking a powerful medication every day, for years.”

Holly Grigg-Spall, Journalist

“The advent of effective contraception was revolutionary, transforming, empowering, and a tremendous boost to women’s health. It continues to play a major role in the effort to achieve responsible reproductive health and choice for all women—a goal of every child being a wanted child delivered into a supportive and secure environment.”

James N. Martin, MD, Jackson, MS Secretary, The American College of Obstetricians and Gynecologists

“If the pill was as revolutionary, transforming and empowering as is suggested, then all women should be taking it from menarche to menopause, except when we are ready to have the “wanted child.” But we aren’t. Today, young women are ditching the pill in favor of non-hormonal methods, and still managing to achieve responsible reproductive health choices. As for the pill being ”a tremendous boost to women’s health” – I think not. Troublesome side effects, serious health concerns, and a growing interest in holistic approaches to health care are putting the pill in its proper place. One contraceptive choice that works for some women, some of the time.”

Laura Wershler, Sexual Health and Reproductive Rights Advocate,
Executive Director, Sexual Health Access Alberta


“The pill is probably the single biggest contribution to women’s health in our lifetime. Not only has it given women more control over their fertility, it has been successfully used to treat many gynecologic conditions such as dysmenorrhea, menometrohaggia, PMS, acne, PCOS, and endometriosis, enabling women to have a better quality of life.”


James A. Macer, MD, Pasadena, CA

Assistant Secretary Elect, The American College of Obstetricians and Gynecologists


“Long term safety data on the current patterns of use of the pill do not exist, and are not being collected. When first approved, the pill was available to married women, most of whom had children, and allowed them to space their families. Currently, the pill is most commonly used by childless young women, often during the teen years, and can extend for decades. The consequences of pharmaceutical suppression of the developing endocrine system (during the 12 years following the first period) have, to my knowledge, not been explored. For example, taking the pill interferes with bone acquisition, compromises the accumulation of bone density, and may compromise peak bone mass. Peak bone mass sets the bar for lifelong bone health. In a cohort expected to live into their 80’s, casual and enthusiastic use of the pill may be something society regrets half a century from now. There is a tendency to blame side effects on the bad old days, and to say that things are better now. But a recent large study confirmed blood clot risks with today’s “modern” formulations, and, more worryingly, these risks are amplified by obesity and smoking, both of which are more prevalent in modern populations.”


Christine L Hitchcock, PhD, Research Associate, Centre for Menstrual Cycle and Ovulation Research, and Clinical Assistant Professor, School of Population and Public Health, University of British Columbia

This ACOG statement furthers a broader message to young women that they should trust pharmaceutical menstrual rhythms over that of their own bodies and that they should trust clinical authority over their own authority. In and of itself, ceding their bodily authority, ownership and stewardship to medicine causes harm to women.

How to overcome resistance to Cycle-Stopping Contraception (a physician’s guide)

May 12th, 2010 by Chris Hitchcock

If you’re wondering why your doctor might not take you seriously when you question taking the pill to abolish your periods, you might want to look at this piece of advice.

I had a look at the Clinical Advisor magazine information – it looks like they pay for articles, help to massage them into shape, but as far as I can tell the articles are not peer-reviewed, and the editorial staff do not have any credentials after their names, so they look like non-medical people. But it is freely available on the web, and apparently gets sent to many practicing physicians and nurses. And it’s a lot more readable than other sources of medical education.

The article is framed as a doctor-to-doctor question:

What can I do to overcome patient resistance to continuous use of oral contraceptives (OCs)? So many women say it’s not natural.—SHERRY HILL, ARNP, Bothell, Wash.

And, the answer? Explain the physiology, explain that there is no build up of old blood, that menstrual flow doesn’t have any effect on infections or toxins. And, for talking points, use the educational materials about cycle-stopping contraceptives on the Association of Reproductive Health Professionals web page (coincidentally funded with unrestricted educational funds from companies who happen to make cycle-stopping contraceptive products). And use Malcolm Gladwell’s 2000 article, John Rock’s Error, to reframe monthly menstrual flow as a historic anomaly (”you don’t need that old-fashioned thing”) and help women to see their regular menstrual flow as unnatural, so that the synthetic drugs you are suggesting will seem less unnatural by comparison.

But, ultimately, “if a patient feels that a monthly withdrawal bleed suits her best, many OCs containing 21 active pills and seven inert pills are available.”

I guess the option of using non-hormonal contraception just won’t come up.

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.

Can you make a baby with a bottle of cough syrup?

April 13th, 2010 by Chris Hitchcock

In a story featuring a photo of a lovely couple holding a beautiful newborn, the Globe and Mail (a reputable Canadian national newspaper) has an article this week about using Robitussin as a fertility aid. According to the article, the TTC (trying to conceive) community is abuzz with this.

How an off-label application of over-the-counter cold medicine found a shelf life as a conception tool widely promoted online is a story marked with skepticism and disbelief. Robitussin’s effectiveness has been debated on chat forums, and references to its impact can be found in bestselling pregnancy books. In a time when fertility treatments cost thousands of dollars, it’s not surprising that a $5 solution has intrigued women for more than 20 years. But it is unusual that despite almost three decades of word-of-mouth debate, there’s little scientific evidence to prove that it works – or that it doesn’t – leaving it in a strange realm somewhere between old wives’ tale and unsung miracle drug.

The article later describes the published support for the active ingredient in aiding conception:

So the pill won’t kill me; what’s the point?

March 18th, 2010 by Laura Wershler

Women on the pill live longer. So touts a March 12, 2010 Reuters news story out of London, England reporting on a study published March 11 in the British Medical Journal (BMJ). A misleading headline if ever there was one.

The study followed 46, 000 women for up to 40 years, to see if the mortality risk among women sho have used oral contraceptives differs from that of never users. What the study actually found, according to the public release issued by BMJ on March 12 is this: “Women in the UK who have ever used oral contraceptives are less likely to die from any cause, including all cancers and heart disease, compared with never users.”

The study also found a slightly higher risk (of death, I presume) in women under 45 years old who are current or recent users of the pill.  As such, the authors assert:

Many women, especially those who used the first generation of oral contaceptives many years ago, are likely to be reassured by our results.  However, our findings might not reflect the experience of women using oral contraceptives today, if currently available preparations have a different risk than earlier products.

Readers should note that statements published in re: Cycling are those of individual authors and do not necessarily reflect the positions of the Society as a whole.
