In a retrospective, longitudinal, multicentre study published in Andrology, the effects of the COVID-19 BNT162b2 vaccine on semen parameters were assessed in 37 semen donors at different time points before and after vaccination. A selective decrease in sperm concentration and total motile count was reported 75–125 days after vaccination (P = 0.01 and P = 0.007, respectively) compared with pre-vaccination levels. However, normal levels of these parameters were recovered ≥145 days post-vaccination, and no changes in semen volume and sperm motility were observed.
