Many people seek out unvaccinated sperm due to concerns about the effects of COVID-19 vaccines on fertility and genetics. They may believe, despite scientific evidence to the contrary, that mRNA vaccines could alter DNA or have unknown long-term consequences on reproductive health. This skepticism is often fueled by misinformation circulating online, leading some individuals to view unvaccinated sperm as “pure” or free from potential risks associated with vaccination. Their decision is often based on a desire to avoid any perceived interference with natural conception and future offspring.

Others are driven by broader ideological beliefs, including distrust of pharmaceutical companies and government-mandated medical interventions. People who oppose vaccines on political or personal grounds may seek unvaccinated sperm as part of their lifestyle choices, similar to preferring organic or non-GMO foods. They may believe that remaining unvaccinated is a marker of health or natural immunity, leading them to prioritize sperm from unvaccinated donors. This preference aligns with a general trend of individuals wanting more control over their reproductive choices and the genetic factors influencing their children.

Additionally, some people are drawn to unvaccinated sperm because of fears related to vaccine side effects, even though studies have shown that COVID-19 vaccines do not negatively impact sperm quality or fertility. Concerns about myocarditis, blood clots, or other reported side effects make some individuals hesitant to conceive with sperm from vaccinated donors. In some cases, people are simply following trends promoted by alternative health communities, influencers, or social media echo chambers. While medical experts largely dismiss these fears as unfounded, the demand for unvaccinated sperm has nonetheless grown within certain groups who prioritize personal beliefs over mainstream scientific consensus.
