NS pfizer According to the first Israeli study of its kind, the coronavirus vaccine has no effect on sperm.
The team compared the sperm of each male subject individually before and after vaccination.
“We did not see any difference in sperm parameters for all groups,” explained Safari. Jerusalem Post.

The researchers also ran a sub-analysis, specifically examining whether the vaccine had a potentially greater effect on men whose sperm were already considered “weak” or impaired: there were none.
In contrast, several studies have found a significantly negative effect of the virus on sperm parameters.
“We know that 25% of men with the coronavirus will also have sperm deficiency,” Safrai said. “Couples who want to conceive – we need to vaccinate them more.”
He said a separate study he conducted earlier showed that the vaccine also did not impair female fertility.
There’s a lot of misinformation about vaccinations, Safari said. “It is important to share the data and confirm for the population that there is no reduction in fertility.”
