Does a sperm count of 38 million is sufficient to get pregnant
Answers
Sperm are constantly in danger. Inside the testicle it takes a sperm about 72 days to go from a germ cell to a fully mature sperm cell capable of fertilizing an egg. During that time, it needs proper nutrition and temperature to develop normally. Once mature, sperm are stored in a long tube called the epididymis where they wait to be ejaculated. Like tiny engines, mature sperm cells produce a form of exhaust known as reactive oxygen species that can damage the cell’s membranes. After about a week in the epididymis, sperm cells that haven’t been ejaculated begin to die.
For the lucky sperm that make it into the female’s body, it’s a whole new world of danger. Vaginal walls tend to be acidic to protect women from potential infections. During the fertile window, the female creates a sperm friendly fluid that enables sperm to swim up towards the egg. Sperm are not that smart. Many of them get lost in the cervix. Those who do make it into the uterus are greeted by white blood cells that see the sperm as invaders and attack them. These sperm swim like crazy to try to find the Fallopian tube while avoiding white cells. Finding the fallopian tube is like finding a needle in a haystack. Of the millions of sperm released upon ejaculation, only a handful make it to the fallopian tube where the egg is released. There, the sperm must survive long enough to meet and fertilize the egg.
So, for men, fertility is a number’s game. The more healthy swimmers you send in, the better your chances are that one of them will find the egg. However, it is very hard to precisely correlate sperm count to chances of pregnancy. A man that has a low sperm count with healthy sperm may have a better monthly chance of conceiving than a man who has a higher sperm count but the sperm are unhealthy. Several large scale studies have analyzed the relationship between semen quality and how long it took a couple to get pregnant. Thnx
