Pfizer, Moderna COVID-19 Vaccines Do Not Lower Sperm Count: Study

Study On Pfizer, Moderna Covid Vaccine Effect On Male Fertility: The study, published on Thursday in the journal JAMA, recruited 45 healthy male volunteers aged 18 to 50 years scheduled for mRNA COVID-19 vaccination by Pfizer-BioNTech and Moderna.

COVID-19 vaccines by Pfizer and Moderna do not harm male fertility, suggests a study which found the levels of sperm in participants remained at healthy levels after they got two doses of the mRNA preventive. The study, published on Thursday in the journal JAMA, recruited 45 healthy male volunteers aged 18 to 50 years scheduled for mRNA COVID-19 vaccination by Pfizer-BioNTech and Moderna. The participants were pre-screened to ensure they had no underlying fertility issues. Those with COVID-19 symptoms or a positive test result within 90 days were excluded. The men provided a semen sample after two to seven days of abstinence, prior to receiving the first vaccine dose and approximately 70 days after the second shot.
