Following the Eve path in their GenderMap, they become sterile females. So GATE 2, Gonadal Sex, also produces some different sexual flavors. We enter GATE 3, the Sex Hormonal Gate of our gendermap in the third month of pregnancy. They all influence our physical development and our sexual behaviors, until we die. Weeks later, at GATE 4, we develop our internal sexual anatomy.
Most boys develop sperm ducts, prostates and seminal vesicles.
Most girls develop a vagina, uterus and fallopian or egg tubes. But some are born with no internal sexual organs other than their testes. These individuals have 46,XY plus a gene mutation that prevents them from producing the protein their body cells need to get testosterone out of the blood into cells. Without testosterone inside the body cells, nothing gets masculinized, and this 46,XY embryo follows the Eve path in its gendermap to become a sterile female. But there are variations of ambiguous external genitals, perhaps as many as 65,000 newborn infants a year in the United States.
