Mild COVID Cases May Affect Men’s Fertility: Study Finds Long-Term Decline in Semen Quality

Men Infected with Even Mild COVID Cases Experience Long-Term Decline in Semen Quality


A recent study presented at the 39th annual meeting of the European Society of Human Reproduction and Embryology (ESHRE) has revealed that even mild cases of COVID-19 can affect a man’s semen quality months after infection.

The Study

The study, conducted on 84 men between the ages of 22 and 54, found that 60% of them had a decline in semen quality after contracting COVID-19. The decline was measured by a decrease in sperm concentration, motility, and morphology.

How COVID-19 Affects Semen Quality

It is believed that COVID-19 can affect semen quality in a number of ways. The virus can cause inflammation in the testicles, which can lead to a decrease in sperm production. It can also affect the blood vessels that supply the testicles, which can cause damage to the sperm.

The Long-Term Effects

The long-term effects of COVID-19 on semen quality are still unknown. However, the study found that even mild cases of the virus can have a lasting impact on a man’s fertility. It is recommended that men who have recovered from COVID-19 and are planning to have children should have their semen quality checked.


In conclusion, the study has shown that COVID-19 can have a significant impact on a man’s semen quality. It is important for men who have recovered from the virus to have their semen quality checked if they are planning to have children. The long-term effects of COVID-19 on fertility are still unknown, but the study highlights the need for further research in this area.
