Pushing back against the recent wave of feminist authors and activists calling on women to embrace their periods, Davis points out that periods are inconvenient and cause pain and discomfort in some women. And further, having a period every month may not be as &#8220;natural&#8221; as it seems, because in earlier days women experienced far fewer periods due to more pregnancies and breastfeeding.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">And then Davis drops a bombshell: she quotes a couple of medical doctors who suggest that 99% of women do not need to bleed and there is no health benefit to doing so. The doctors she quotes argue that hormonal contraception can be taken continuously to prevent any bleeding, with no negative consequences.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">These are glaring claims, and what&#8217;s missing is any evidence to support them. It seems it is the opinion of the few doctors interviewed that menstrual cycles are not necessary, but opinion does not equal fact. Especially when this opinion directly contravenes the endocrine society practice <\/span><a href=\"https:\/\/academic.oup.com\/jcem\/article\/102\/5\/1413\/3077281\"><span style=\"font-weight: 400;\">guidelines around amenorrhea<\/span><\/a><span style=\"font-weight: 400;\">[1].<\/span><\/p>\n<p>Bleeding itself is not a health benefit, but it is evidence that ovulation is occurring. Why does it matter that ovulation is occurring?

To argue that replacing just one or two with synthetic versions that may or may not activate receptors in exactly the same way as the natural form is going to fulfill all the same functions as those 20+ hormones is not logical.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">It is irresponsible to ignore years of medical literature and make the claim that there is no need to bleed (and by extension, no need to ovulate). It is irresponsible to gloss over side effects of hormonal birth control and make it sound like a panacea, particularly if it is taken to correct a period issue with a treatable medical underpinning.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Of course, every woman has the right to make her own choices around reproductive health care, and for many women, the hormonal birth control pill or other options that prevent ovulation and bleeding may be the best option. For other women, a non-hormonal method of birth control that ovulation intact is preferable. Importantly, making the optimal choice given needs, desires, and health, requires accurate and complete information. Medical professionals and journalists should be presenting women with a summary of ALL the evidence so they can make truly informed decisions.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Writing for the Guardian, Nicole Davis makes a strong claim: that there&#8217;s no need for
