Sometime between June of 2021, and early 2022, Moderna vaccination resulted in permanent damage to my reproductive system. Tests done in 2022 and 2023 have shown that there are no sperm cells seen in the samples. Before vaccination, semen tests (done in 2015 and June 2021) have shown normal amount of motile sperm cells. The detailed timeline of semen tests performed is shown on the next page. There were no other events or problems (no health problems, no injuries) that would explain that sperm cells stopped generating in my reproductive system, pointing to vaccination as the reason of the problem. (See next page) Timeline of tests done for semen analysis before and after vaccination: Oct 20, 2023 Lab test of semen no sperm cells seen Feb 17, 2023 – test of semen no sperm cells seen Feb 10, 2023 test of semen no sperm cells seen During 2022 self-tests with microscope, seen gradual decrease of moving sperm cell numbers, and moving cells seen not on every try Dec 12, 2021 Moderna 60H21A mRNA booster June 29, 2021 Lab test of semen and count normal results and good motility (12×10^6) May 16, 2021 Moderna 014C21A mRNA vaccination Apr 18, 2021 Moderna 046B21A mRNA vaccination Jan 2015 Lab test of semen and count normal results and good motility (14×10^6) Another troubling fact is that my wife, who received the same Moderna vaccinations, have lost ability to remember any new information sometime in summer of 2021, and after that her brain degeneration was developing exponentially. Please see report VAERS ID: 2822907, E-Report Number: 1050478 for wife’s case. In addition to this permanent damage to reproductive system, I have also started to notice, since August 2021, heart palpitations. I never had any problems with heart before. I have followed with cardiologist. Ultrasound tests haven’t shown any specific issues in the heart. After about two years, palpitations were gone. However, reproductive system was damaged permanently, as confirmed by periodic tests done in 2024 and 2025. Seeing that two people who received same vaccinations had damaging impacts, one can conclude that either a) it is possible that these specific batches of vaccines are in particular damaging; or b) patient and I were both damaged by vaccine because we came from a very similar ethnic group. Hope science research on these questions will be launched, helping people in the future.
