Things men should know: Will sperm run out?

Although men are more lustful, very few of them really understand sex knowledge. After all, sex education has not been fully popularized in our country. Some men believe that one drop of semen is equal to ten drops of blood, and a man's sperm will eventually run out. From a medical point of view, is this really the case?

Can sperm really run out?

Running dry is a terrible nightmare. Is it possible? The answer is no, but there is some bad news. Women carry all the eggs they need for their whole lives from birth, while men must continue to produce sperm. This sounds good. But researchers have found that after men turn 35, sperm activity becomes abnormal and their DNA is somewhat damaged. According to WHO research, the number of sperm a man ejaculates now is about 20 million, and the sperm activity rate is 50%; this is a big difference compared to 25 years ago, when the number of sperm could be as many as 100 million. So if you want to have a baby, hurry up.

Does underwear really affect fertility?

Everyone has their own preferences. For example, Clinton once said that he likes to wear boxer briefs. Berlusconi likes sexy briefs. It was originally believed that wearing tight underwear would lead to male infertility because tight underwear would increase the temperature of the testicles and interfere with sperm production. A recent study in the Journal of Urology showed that there was actually no significant difference in sperm count, sperm concentration and motility when men wore tight underwear and loose underwear. This is thanks to the scrotum, whose function is to maintain the temperature of the testicles. No matter what you wear or not, it will do its job. So you can choose the underwear you like, and your sperm will not feel the difference at all.
