Clinical narrative: PRIVATE & CONFIDENTIAL   (This is my second language and I try to make it as clear as I can)  1.First two doses of Moderna (4/16/2021 & 5/14/2021) I received a total of three doses of covid-19 Moderna vaccine. Sometime right after the first two doses on 4/16/2021 and 5/14/2021, I found my sexual function was abruptly and significantly decreased and I do not remember the exact day I found it. The adverse event was strange and unexpected as it had never happened before. I had had very normal and healthy function for decades since my puberty to the time I received the vaccine in 2021. (See the continuation page) I was looking for the cause in my mind and thought it might just be temporary whatever the cause. At the time, I did not connect the adverse event with the vaccine. All public information says the vaccine is safe.   The symptoms after 1st and 2nd doses: 1) When ejaculation/orgasm, the nerves/neural system's ability to feel sexual pleasure was abruptly and significantly decreased to a lower level, probably decreased by half maybe more;  2) Erectile quality abruptly and significantly decreased to a lower level.    2.The third dose Moderna (booster shot) (11/23/2021)      The function remained at a decreased level for about half year until the third dose on 11/23/2021. Right after the 3rd dose, my sexual function further abruptly and significantly decreased from the already decreased level in the same way I had experienced after the first two doses.   The symptoms after 3rd dose:   1) When ejaculation/orgasm, the nerves/neural system's ability to feel sexual pleasure completely disappeared;  2) Erectile quality got worse.   The process of erection and ejaculation is still can be completed but with poor quality. Also, the decreased function and the symptoms etc. resulted in decreased desire or low libido.   This time, I started to realize the connection between the adverse event and the vaccine. There was no other obvious reason other than the vaccine can explain it.   I went to see doctors in 2022 and 2023 after the symptoms of the adverse event appeared to be permanent with no sign of recovery. I had a couple of tests including UA etc. and the results were fine. Given the root cause of the adverse event, it is a new issue to everyone doctor, so there were no effective solutions from doctors.           The doctors suggested that might be because of aging. However, the way and the timing that my function abruptly and significantly decreased after receiving 1st, 2nd doses vaccine and decreased again after the 3rd dose vaccine indicates that aging was not the cause because is vastly different from the way of natural and very slow declining due to aging, for example, my function at the age of 40s is slightly declined than it was the age of 30s, which was also slightly declined than it was at the age of 20s. Put it in another way, the damages of a piece of furniture broken by a hammer are different from the damages of a piece of decades old, but still fully functional, furniture only with signs of cosmetic wear due to its age.                     I hope this report can be bought to medical researchers' attention regarding the side effect of the vaccine. More specific symptoms of the adverse event could be provided if necessary for medical research purposes.
