Will getting the vaccine make men sterile?

COVID-19 vaccines don’t cause sterility: The COVID-19 vaccine will not make you sterile. Some people (about 16%) get a mild fever for a day or two – and any fever will temporarily reduce sperm count.

On the other hand, men are more likely to get COVID-19, more serious cases, and die more often than women.

A serious case of COVID-19 can reduce fertility. According to the Journal of the Society for Fertility and Reproduction “Current studies confirm that SARS-CoV-2 can affect the male reproductive system. Abnormal levels of sex hormones and declining sperm quality were observed in patients during and after recovery from COVID-19.” The worse the case, the worse the impact. 

COVID-19 vaccines protect fertility. There’s no evidence that the vaccines harm fertility, but there’s a lot of evidence that the disease does. So if you’re worried about fertility – get vaccinated. 

Being alive is sexy.
