The lifespan of sperm cells: Longevity, withdrawal, and fertility

Since the late s, scientists have explored how to produce sperm where all of the chromosomes come from a female donor. Creating female sperm was first raised as a possibility in a patent filed in [3] by injecting a woman's cells into a man's testicles, though the patent focused mostly on injecting altered male cells into a man's testes to correct genetic diseases. In , Japanese scientists partially confirmed such techniques by creating chicken female sperm in a similar manner. It is therefore concluded that most of the W-bearing PGC could not differentiate into spermatozoa because of restricted spermatogenesis. One potential roadblock to injecting a woman's cells into a man's testicles is that the man's immune system might attack and destroy the woman's cells. In usual circumstances, when foreign cells such as cells or organs from other people, or infectious bacteria are put into a human body, its immune system will reject such cells or organs.

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. The rest are attacked and absorbed by white blood cells, which start to appear in force as soon as sperm enter their defensive perimeter.
