COVID-19 vaccines may reduce women’s lifelong supply of eggs, drastically reducing their fertility, according to a new study.
The study, conducted by Turkish researchers, investigated the effects of the mRNA and non-mRNA vaccines on female reproductive health.
Female rats were given COVID vaccinations and their ovarian tissue was harvested and analysed.
The results showed that administration of the both kinds of vaccines reduced the number of primordial follicles, which go on to become eggs and are limited in number.
The potential implications for women are serious.
“If these findings indeed apply to humans, the implications for global fertility rates are profound,” wrote epidemiologist Nic Hulscher on Substack.
He added, “This kind of damage—to a woman’s lifelong egg supply—is biologically irreversible. The loss of primordial follicles is permanent—they do not regenerate. If this applies to humans, it means early menopause, infertility, and plummeting birth rates.”
The new study also showed other worrying reproductive changes in the ovarian tissue of the female rats.
Levels of a crucial hormone decreased, which is indicative of reduced reproductive health, and an enzyme associated with a variety of conditions including fibrosis and follicle damage was increased.
These changes were particularly marked in rats that were administered mRNA vaccines.
Another recent study showed that Czech women who received COVID-19 vaccines had roughly 1/3 fewer successful pregnancies than unvaccinated women.
The total fertility rate in the Czech Republic decreased 21% during the period of the study.
