Study on how coronavirus can affect fertility in men

COVID could damage the testicles, reduce libido and affect fertility in men, a recent study by a group of scientists from the University of Hong Kong has revealed. The study was based on testicular and hormonal changes in hamsters infected with the coronavirus. Omicron and Delta can cause such complications, he also said.

Hamsters infected with the virus showed a sharp drop in sperm count as well as serum testosterone in just 7 days. There was a reduction in the size and weight of the testicles, the study showed.

Acute inflammation of the testicles, hemorrhages as well as tissue death in the seminiferous tubules (responsible for sperm production) were also observed, he also revealed.

“The virus can also reduce libido, as well as subfertility in men.”

The study was led by Professor Yuen Kwok-yung and his team at HKU, as reported by the South China Morning Post.

The researchers also claimed that these changes – degeneration, inflammation as well as death of testicular tissue – were observed within 7 days to 4 months after contracting the infection. The omicron and delta variants can cause these changes.

However, such complications could be avoided through vaccination.

Should we be worried?

A recent Japanese laboratory study on hamsters revealed that Omicron BA.2 can cause serious infections. However, looking for severity signals in humans, in terms of increased risk of hospitalization in people who have been infected with BA.2 compared to BA.1, it was observed that no no greater severity in humans. Both subvariants cause a similar level of severity.

According to officials of the World Health Organization (WHO), these studies are very important in the search for signals of gravity. But the level of severity in the lab and in the real world may be different.

Similarly, for the study relating to how the coronavirus affects fertility in men, it remains to be determined.
