Unlike a woman who will have around mature eggs throughout a lifetime, which can be released from the follicles in the ovaries and potentially be fertilized, a healthy man will produce billions of sperm in his entire lifetime. All the sperm production and maturation take place in the lumen of the seminiferous tubules of the testis as shown in figure 1. Within the walls of these tubules the sperm cells are produced and matures. Also, in the tubes, there are many different cells of which the most important is the Sertoli cells.

Mike Leahy - writing with Hilary McQueen - gets to grips with the numbers behind the man's part of the reproductive system - sperm. Although I'm a biologist, I rarely think much about what the cloudy white stuff contains, but in fact semen is far more complex than my endearing childhood image of mini tadpoles swimming around in thin wallpaper paste. There are many features of human semen that are very familiar to most people, but their importance isn't appreciated. For a start, the ejaculate isn't of a uniform consistency. As the man ejaculates, the first 'spurt' contains far more sperm than subsequent spurts.

The good news, there are some very tangible lifestyle changes that men can make to improve their sperm health and overall fertility. It is generally known that most men produce millions of new sperm every day. You also might not realize that when sperm are initially formed within the testicles, they lack the ability to swim forward or fertilize an egg until they make their way through the reproductive tract. Sperm are living cells within the male body and are subject to whatever conditions the rest of the body is exposed to throughout their development cycle. Extreme temperatures, smoking, drug use, and poor diet can all impact the quality of sperm.

On average, it takes a male around 74 days to produce new sperm from start to finish. Although the average time is 74 days , the actual time frame for an individual to make sperm can vary. The body produces an average of around 20— million sperm cells per milliliter of semen.
