Pfizer, Moderna COVID-19 vaccines don't lower sperm count, study says

Meanwhile, average sperm counts increased from 36 m/ml to 44 m/ml, a 22 percent increase

COVID-19 vaccines do not reduce the sperm count or quality of men. Vaccines may even increase the amount of semen they produce, a new study suggests.


The study, published in JAMA. The team of researchers at the University of Miami recruited 45 men aged 18 to 50 years old, all of whom had no previously known case of COVID-19 and did not exhibit symptoms of the virus to analysis.


The researchers analysis semen before receiving their first vaccine dose. Their sperm counts were analyzed once again 70 days after they received the second dose of either of the vaccine.


The median sperm count increased from 26 million cells per milliliter of fluid (m/ml) to 30 m/ml, a 15 percent increase. Meanwhile, average sperm counts increased from 36 m/ml to 44 m/ml, a 22 percent increase.


So the researchers did not find any sperm count reductions for men who had received either one or two doses of the Pfizer-BioNTech or Moderna vaccine, and the final mean and median sperm counts even increased.


The findings will help counter to false narrative on social media pages and anti-vaccine that the COVID-19 vaccines affect fertility.
