Marijuana Use May Lower Sperm Counts 'Quite a Lot' | Live Science

The prevalence of marijuana use among males of reproductive age has never been higher, while male factor infertility is also on the increase. Researchers believe that the spread of legal medical and recreational marijuana use in the U. Marijuana contains the cannabinoid drug THC tetrahydrocannabinol , its primary psychoactive chemical, as well as other cannabinoids. Several studies have linked marijuana usage and male infertility but how the use of the drug affects infertility has been attributed to a variety of reasons.

The findings are "not consistent" with previous research, which has suggested that marijuana has a harmful effect on men's testicular function, the researchers said. However, the study, published in the Feb. The findings are far from conclusive, and more research is needed to understand whether smoking marijuana could indeed, at certain levels, have a positive effect on sperm production.
