The Sperm Cell: An Overview
You may pretty much have an idea where babies come from. (No, they’re not from the stork!) To put it bluntly, you need a sperm cell and egg cell to make a baby. During sexual intercourse, a man’s sperm, which is produced by the testes (testicles), is released into a woman’s cervix, which ?swims? to the fallopian tube. From the millions of sperm cells, one penetrates the egg in a process called fertilization. From there, a single life begins.
But where does the sperm come from? There are millions of sperm produced by your testes (testicles) everyday. Sperm cells undergo the natural cell division which inevitably leads to its maturation. Half of the sperm carries a Y chromosome (inherited from your dad) and an X chromosome (inherited from your mom). If a Y-carrying sperm fertilizes the woman’s egg, the result is a baby girl. If on the other hand, it’s the X-carrying sperm which fertilized the egg, then it’s a baby boy.
