New Study Says Pot May Boost Sperm Count

Forget everything you thought you knew about marijuana and a man’s seed. A new study from Harvard University claims pot may actually increase male sperm counts, contrary to decades of popular thought.

The study was conducted between 2000 and 2017. Researchers examined sperm counts for 662 men at the Massachusetts General Hospital Fertility Center. What they found was shocking. The 365 men who had smoked marijuana at some point in their lives had 63 million sperm per milliliter of semen, compared to an average of 45 million sperm per millimeter for the group that had never smoked.

Testosterone levels were also higher among men who had smoked recently. But in terms of sperm count, the study found no discernible difference between men who had recently smoked or not.

The study suggests that years of conventional wisdom about pot’s destructive effects on sperm may be overblown — and that there may even be some reproductive benefits to trying weed.
