If you've been confused about whether or not smoking weed affects sperm count, you're not alone. Here's what experts are saying. New OHSU research follows the university's earlier findings: chronic cannabis use reduces male fertility in animal models; will help inform ongoing studies on the topic. Marijuana's impact on men's sexual health is the focus of a study by Omer Raheem, MD, who is heading up University of Chicago Medicine's new research project. For immediate release: February 5, 2019. Boston, MA – Men who have smoked marijuana at some point in their life had significantly higher concentrations of sperm. The investigators also observed that among marijuana smokers, only 5 percent had sperm concentrations below 15 million sperm per milliliter of fluid. In short, yes — cannabis use does seem to affect the overall health of sperm. Although more research on cannabis and sperm health is needed, ongoing studies are shedding light on the topic.
Research on pot and sperm quality, gene expression, and child development. The research builds on previous discoveries made by OHSU, indicating that persistent use of cannabis could potentially impair male fertility in animal models. As more states legalize marijuana, a new study by a Tulane University researcher has a warning for would-be dads. Smoking weed regularly may have negative effects on sperm health and fertility. While the exact mechanisms by which cannabis affects sperm are still being studied, the evidence so far suggests a correlation between marijuana use and decreased sperm count and quality.
