Sperm quality is not affected by the BNT162b2 mRNA SARS-CoV-2 vaccine: results of a 6-14 months follow-up.

ABSTRACT:

Purpose

We aimed to investigate the possible effect of SARS-CoV-2 vaccination on sperm quality by evaluating semen analyses of men prior to vaccination and 6-14 months after vaccination.

Methods

This was a retrospective cohort study, conducted in a university-affiliated in vitro fertilization center between October 2021 and March 2022, including men not previously infected with the SARS-CoV-2 virus who received at least 2 doses of the Pfizer-BioNTech (BNT162b2) SARS-CoV-2 vaccine. Semen analyses of samples given pre-vaccination and 6-14 months post-vaccination were analyzed for the parameters of volume, concentration, motility, morphology, and total motile count (TMC) and compared. These parameters were also compared separately for men who received a third (booster) dose and
