There are approximately million sperm in each human ejaculation, but only about 2 million sperm make it into the cervix. Out of the approximately 2 million sperm entering the cervix, only about 1 million make it into the uterus. The rest are stopped by gooey mucus, or swim into dead-end channels inside the walls of the cervix. Out of the approximately 1 million sperm that enter the uterus, only about 10, make it to the top of the organ.

Female sperm

The study found that one transgender woman was able to produce viable sperm after a few months of discontinuing her puberty-halting medication, whereas a different patient on hormone therapy discovered sperm production was not possible during the time she could psychologically tolerate being off her medication. The research team examined medical records of two transgender women who tried to preserve their sperm after stopping hormone therapy and compared the quality of semen against eight other transgender women who elected to preserve their sperm before beginning therapy. All of the study participants came through the Fertility Preservation Program in Pittsburgh between and as young adults. One of the patients who elected to preserve their sperm after beginning therapy had been taking the drug Lupron, a sex hormone blocker that halts puberty when taken in adolescence, for six months.
