Omicron may affect the fertility of boys, but there is no relevant evidence that it necessarily does. According to current clinical studies, some men may experience reduced sperm count and decreased sperm viability even after recovering from omicron infection, and some patients may also experience severe impairment of testicular function, which further affects sexual function and may also have an impact on fertility, but it is not a 100% threat to fertility. Most of the patients infected with Omicron can be controlled through regular treatment, and this group of patients generally does not affect fertility. If you have been infected with Omicron and are concerned that it may affect sperm quality and threaten fertility, regular monitoring of sperm viability and other tests are recommended.
