The male reproductive system

Male fertilityThe normal sperm production

The sperm cells are produced in the testicles. At the ejaculation the sperm cells run through the epididymis, here the sperm cells are mixed with liquid from the prostate and the seminal vesicle and are then ejected through the urethra. One single ejaculation normally contains approx. 4 millilitre yellow-white thick liquid. This liquid is called the sperm or the semen. Normally, one ml semen will contain approx. 50 millions sperm cells.

The quantity of semen does not necessarily tell anything about the quality of the sperm cells. A man with a large quantity of semen might have a poor sperm quality, and vice versa a man with a small quantity of semen might have a good sperm quality. The quantity of semen can vary between 2 to 8 millilitre and is still considered normal.
