1. Physiological characteristics of male sperm vs female egg
Spermatozoa are produced by mature male testes. It usually takes 64 days from spermatogonia to mature spermatozoa, in which there are seven divisions. Each mature sperm contains X chromosome and Y chromosome. There is no upper limit on men’s spermatogenic capacity. The concentration of sperm in each ml of ejaculated semen is more than 20 million to 100 million. Sperm after ejaculation into the female reproductive tract, the life span of 1-3 days, if not with the egg, then slowly lose the ability to conceive. However, studies have shown that fresh sperm can be preserved for a long time without losing energy.
The egg is produced by ovary, which is the largest cell in human body. The diameter of mature follicle is about 18mm. When a baby girl is born, there are as many as 450000 eggs in the womb, but many of them die almost immediately during childbirth, and the remaining eggs decrease regularly with the age of the woman. About 400 eggs are released within a few years of a woman’s fertility. Generally, this period of time refers to from the arrival of menarche to the arrival of menopause.
