The spike protein generated endogenously by the vaccine could also negatively impact the male testes, as the ACE2 receptor is highly expressed in Leydig cells in the testes (Verma et al., 2020). Several studies have now shown that the coronavirus spike protein is able to gain access to cells in the testes via the ACE2 receptor, and disrupt male reproduction (Navarra et al., 2020; Wang and Xu, 2020). A paper involving postmortem examination of testicles of six male COVID-19 patients found microscopic evidence of spike protein in interstitial cells in the testes of patients with damaged testicles (Achua et al., 2021) https://ijvtpr.com/index.php/IJVTPR/article/view/23/51
A Pfizer Confidential study performed in Japan showed that "modRNA encoding luciferase formulated in LNP comparable to BNT162b2′′ injected intramuscularly concentrated in many or-gans/tissues in addition to the injection site [53]. The main organs/sites identified were adrenal glands, liver, spleen, bone marrow, and ovaries. While damage to any of these organs/sites could be serious (if real for humans), adverse effects on the ovaries could be potentially catastrophic for women of child-bearing or pre-childbearing age. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8437699/pdf/main.pdf
