Cannabis Use Doesn’t Affect Sperm Quality, New Study Finds

A study from Boston University suggests that cannabis use does not significantly affect sperm quality.

A recent study from the Boston University School of Public Health indicates that cannabis use does not significantly impact sperm quality. Researchers analysed semen samples from 921 men, assessing semen volume, total sperm count, concentration, and motility. The findings revealed no substantial differences between cannabis users and non-users in these parameters.

These results align with a 2018 study led by Professor Lauren Wise, which found that marijuana use by either partner did not reduce a couple’s chances of conceiving. The study, part of the Pregnancy Study Online (PRESTO), surveyed over 4,000 women and 1,100 of their male partners in the U.S. and Canada. Approximately 14% of male participants reported marijuana use in the two months before the study, yet conception rates remained consistent regardless of cannabis use.
