For much of history, female reproductive anatomy has been studied only in the context of or in comparison to male reproductive anatomy. This shows in clinical trial design, in healthcare disparities, in the research questions we ask (or fail to ask), it’s even apparent in our language – the word “vagina” means “sheath”, as if vaginas only exist to sheathe penises. Only recently have researchers begun to close this gap in our knowledge when it comes to half the humans on this planet. In Vagina Obscura: An Anatomical Voyage, award-winning journalist and author Rachel Gross takes readers through the origins of this information gap, examining how preconceived notions about sex and gender underlie the bias that still exists today. She then delves into the fascinating research that seeks to confront this bias and address the vast health inequities that limit care for so many. Tune in for a truly enlightening odyssey through the only recently charted world of female anatomy.
