Medicine has not taken the intricacies of the female body into account – and so “women’s health” became synonymous with reproductive organs. It was only during the 21st century that such obsolete ideas were challenged by the emergence of evidence that women experience heart attacks differently than men. The difference comes right down to the cellular levels. Research published by Israel’s Weizmann Institute of Science in 2017 found that around a third of the 20,000 genes present in a cell express themselves differently in males and females[1]. Yet, why is the unique physiology of a woman not taken into consideration? How can we as medical students change this?

One way is using an equal number of male and female mice during research. Among 1200 neuroscience papers from 2011 and 2012, only 42% reported the sex of the mice used of which only 24% were female[2]. Secondly, we need a gender specific approach to any treatment procedure. Kautzky-Willer’s research specializes in diabetes and she has found that women usually have a lower fasting glucose and HbA1C than men. She hypothesizes that a separate blood test with different cutoffs or biomarkers will be needed to diagnose diabetes in men and women[3]. Similar conclusions are occurring in varying fields of medicine; for example, women are more sensitive to antihistaminic drugs and aspirin is more effective in stroke prevention in woman but heart attacks in males etc[4].

Unfortunately, findings such as these have not had widespread impact on diagnosis and treatment. A vast majority of diagnoses, therapies and drug dosages for common conditions are still based on symptoms, responses and outcomes in Caucasian adult males.  Berga says that there are two things going on at once- “One is the urge to simplify to make things efficient, to arrive at something that’s one size fit all. The other is that if something does not work in one size fits all model, then you have to find the reason and determine what should be changed, and you run into questions about how much it will cost to do this, how long it will take and so on” [5].

The “one size fits all” theory can be disproven by having an inclusive list of participants. A 2010 study from the Duke Clinical Research Institute in the USA found that only a quarter of those involved in coronary artery disease trials are women [6]. Shockingly enough the study to demonstrate alcohol interaction with Flibanserin (a drug which was passed by the FDA for treatment of hypoactive sexual desire disorder in premenopausal women) enrolled 23 men and 2 women and thus many researchers like Dr. Mazure expressed concern over the nature of the study [7]. Medical students should also acknowledge the limitations of medicine with respect to women instead of dismissing them as “hysterical” and invalidating their negative experiences. Dr.Young reports of how women who were ineffectively treated by current medication of endometriosis were labeled as “difficult” [8].

Thankfully not all hope is lost. In 2013, the FDA applied new recommendations for lowering the dosage of drugs containing active ingredient Zolpidem[9]. In 2016 the NIH began to mandate that research should include female animals [10].
