Pfizer mRNA Coronavirus Vaccine “Temporarily” Decreases Male Fertility

by Chris Black

Now we have a study that claims the mRNA gene therapy provokes male infertility.

Who could have predicted this?

At this point, they are letting these studies happen, because it doesn’t matter anymore, the harm has been done already and there’s nothing you can do about it.


Here’s the abstract of the study:


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 TMC reductions on T2 compared to T0 – median decline of 12 million/ml and 31 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. Semen volume and sperm motility were not impaired.

This longitudinal study focused on SD demonstrates selective temporary sperm concentration and TMC deterioration three months after vaccination followed by later recovery verified by diverse statistical analyses.


Systemic immune response after BNT162b2 vaccine is a reasonable cause for transient semen concentration and TMC decline. Long-term prognosis remains good.

Adults “recover” when it’s about time for their next booster, but what’s the damage to the developing testicles of males going through puberty?

 What’s the damage to little kids? 

What are the long term effects of repeating doses?
