The size of a clenched fist and the shape of a light bulb--with no less power and potential. Every person on Earth began inside a uterus, but how much do we really understand about the womb? Bringing together medical history, scientific discoveries, and journalistic exploration, Leah Hazard embarks on a journey in search of answers about the body's most miraculous and contentious organ. We meet the people who have shaped our relationship with the uterus; doctors and doulas, yoni steamers and fibroid-tea hawkers, legislators who would regulate the organ's very existence, and boundary-breaking researchers on the frontiers of the field. With a midwife's warmth and humor, Hazard tackles pressing questions: Is the womb connected to the brain? can cervical crypts store sperm? Do hysterectomies affect sexual pleasure? How can smart tampon help health care? Why does endometriosis take so long to be diagnosed? Will external gestation be possible in our lifetime? How does gender-affirming hormone therapy affect the uterus? How does medical racism impact reproductive health care? --
