The biological mechanism are complex, and since it is described by Dr Sonia Elijah in a discussion with Dr Naomi Wolf, is best viewed as there was no written transcript to ponder, by a non-scientist like me, but still the issues are important. The simple take home message from the discussion of the effects of the Covid mRNA vaxxes upon women's fertility, is primarily negative. It seems that scientists, the few working in the area of vaccine harms and women's reproductive health, have found that there is a mechanism that can produce infertility. The mRNA vaxxes produce a chemical which affects the regulation of the woman's fallopian tubes releasing the ovum for fertilisation. It is not known the extent of the vax/fertility problem, but Dr Elijah, notes that there is, along with the excess deaths issue, a statistically significant rise in fertility issues beginning at the precise time of the Covid vax rollout, which has not decreased.
Dr Wolf has been presenting evidence of the harmful effects of the Covid vaxxes upon women's health since June 2012, which led to her global cancellation and deplatforming. Note as well that she is a feminist coming from the Left. It did not make any difference at all; attack the sacred vax and you will be shredded if a public figure. If not a public figure, then it may just be a visit from the "friendly" neighbourhood police.

"It's abundantly confirmed now that the mRNA injections destroy women's sexual health, a story Dr Wolf broke in June 2021, that led to her global deplatforming. In this important interview, Sonia Elijah explains a major study that has identified the mechanism whereby this suffering and infertility is being caused. The injections actually dysregulate the chemicals needed for the fallopian tubes to release the ovum for fertilization. This is a tragic and historic interview, which shows the way, we hope, toward treatment."
