The conspiracy realists were right again.
The development of covid-19 vaccinations represents a notable scientific achievement. Nevertheless, concerns have been raised regarding their possible detrimental impact on male fertility
To investigate the effect of covid-19 BNT162b2 (Pfizer) vaccine on semen parameters among semen donors (SD).
Thirty-seven SD from three sperm banks that provided 216 samples were included in that retrospective longitudinal multicenter cohort study. BNT162b2 vaccination included two doses, and vaccination completion was scheduled 7 days after the second dose. The study included four phases: T0 – pre-vaccination baseline control, which encompassed 1–2 initial samples per SD; T1, T2 and T3 – short, intermediate, and long terms evaluations, respectively. Each included 1–3 semen samples per donor provided 15–45, 75–125 and over 145 days after vaccination completion, respectively. The primary endpoints were semen parameters. Three statistical analyses were conducted: (1) generalized estimated equation model; (2) first sample and (3) samples’ mean of each donor per period were compared to.
Repetitive measurements revealed −15.4% sperm concentration decrease on T2 (CI −25.5%–3.9%, p = 0.01) leading to total motile count 22.1% reduction (CI −35% – −6.6%, p = 0.007) compared to T0. Similarly, analysis of first semen sample only and samples’ mean per donor resulted in concentration and total motile count (TMC) reductions on T2 compared to T0 – median decline of 12 million/ml and 31.2 million motile spermatozoa, respectively (p = 0.02 and 0.002 respectively) on first sample evaluation and median decline of 9.5 × 106 and 27.3 million motile spermatozoa (p = 0.004 and 0.003, respectively) on samples’ mean examination. T3 evaluation demonstrated overall recovery without. Semen volume and sperm motility were not impaired.
