In Parts 1 and 2, I wondered why author Ann Patchett chose not to include information about menstruation, femcare products and birth control that, logically, would have enhanced her novel’s inciting premise—lifelong menstruation and fertility—while retaining the literary integrity of State of Wonder. I believe just a few sentences could have accomplished this.
The reader learns with Dr. Marina Singh, the novel’s protagonist, that the Lakashi women continue to menstruate, ovulate, conceive and give birth into their 70s because they regularly chew the bark of Martin trees found in the Brazilian rainforest. The bark is so effective there are no post-menopausal Lakashi.
The women chew the bark once every five days except when they are menstruating and when they’re pregnant, because the bark repulses them from the moment of conception. The researchers, led by Dr. Annick Swenson who has been studying the Lakashi for decades, observe the women chewing the bark and collect cervical mucus swabs to monitor their estrogen levels. They dab the swabs on slides for “ferning.”
“No one does ferning anymore,” Marina said. It was the slightly arcane process of watching estrogen grow into intricate fern patterns on slides. No ferns, no fertility.
Dr. Saturn shrugged. “It’s very effective for the Lakashi. Their estrogen levels are quite sensitive to the intake of the bark.”
Patchett perpetuates the myth that fertility is all about estrogen. Actually, fertility is dependent upon the the cyclical ebb and flow of estrogen and progesterone. Estrogen levels build in the pre-ovulatory phase; when estrogen (and the ferning quality of cervical mucus) peaks, ovulation occurs. Estrogen drops quickly, mucus dries up (no ferns), the fertile phase ends and progesterone levels rise dramatically to act upon the endometrium in preparation for pregnancy. It would make sense for the Lakashi to chew the bark more often during the pre-ovulatory phase but be repulsed by it post-ovulation as progesterone rises. How neat would that have been? The researchers could have pinpointed ovulation in the Lakashi. Oddly, ovulation is not even mentioned.
Further, if intake of the bark raises estrogen levels, chewing the bark every five days would interfere with the post-ovulatory rise of progesterone, throwing the hormonal interplay of estrogen and progesterone required to achieve and support a pregnancy out of whack.
Another issue: Marina is told that by chewing the bark “her window for monthly fertility would be extended from three days to thirteen.” What does this really mean? According to the scientific principles underlying the fertility awareness method of achieving or avoiding pregnancy, the fertile phase starts when fertile-quality cervical mucus is first observed and ends when three dry days have passed. The bark would increase the fertile quality of the mucus and the number of days fertile mucus occurs pre-ovulation, thereby increasing the chances for conception. But sperm can only survive five days, kept viable by the mucus that locks it in the cervical crypts until an egg is released. And that egg will remain viable for only 24 hours. Timing of intercourse still matters. The extended fertility explanation in the novel does not suggest the Martin tree bark has any effect on these accepted reproductive factors.
Am I being too picky? Perhaps. State of Wonder is, after all, a work of fiction. But I expect a seasoned novelist to have researched basic menstrual cycle facts so as not to pose an explanation for extended fertility that doesn’t pass scrutiny. Had Patchett consulted with a menstrual cycle expert, perhaps an SMCR member, she might have imagined a much more plausible scenario. In the actual book I read, there were no acknowledgements to those she may have consulted on the subject.
I loved State of Wonder for all it’s literary complexity that goes far beyond the details related to the menstrual cycle that I have wondered about in this 3-part series. But it’s been fun to explore how one novelist wrote about a subject I am intimately familiar with and to suggest how she might have done it differently.
