Very true! I wouldn’t have found out unless I had to go to ER and have a doctor study my medical records for a few hours before meeting with me. I’m part of an ongoing extensive study on aging and every three years I have an assortment of tests done, lung capacity, mobility, height, weight, cognitive tests, EKG, bone density and they collect nine vials of blood. This year I was there for the 1st time as a trans woman and they were delighted to be able to see what differences that would make. Evidently, because of the changes, my blood was extensively tested.
The results, the major one being that I possess what is called a micropenis, along with other more feminine physical attributes I have always had, were what the doctor based her information on.
