Can A Man Ever Run Out of Sperm?

What a nightmare. The well running dry. Could it be possible?


The answer is no, but there is some bad news.


A woman is born with all the eggs she will ever have, but a man’s supply of sperm is
renewed throughout his life. This sounds great, but researchers have found that men over thirty-five have more abnormalities in sperm movement and sperm with more seriously damaged DNA than younger men. It also has been found that over time, average sperm counts have been decreasing.

 

The World Health Organization guidelines say a normal sperm count consists of twenty million sperm per ejaculate, with 50 percent motility and 60 percent normal morphology. This is different than twenty-five years ago when the normal count was near one hundred million.
