Marijuana use may boost sperm count, Harvard study claims

- Wannabe dads now have high hopes.

A new study from Harvard University researchers found men who smoke marijuana have significantly higher sperm counts than non-tokers.

The findings, published Wednesday in the journal Human Reproduction, fly in the face of previous studies that suggest smoking pot can adversely affect male fertility.

The team at Harvard tested 662 men who were enrolled at the Massachusetts General Hospital Fertility Center between 2000 and 2017. From the pool, they collected 1,143 semen samples.

The 365 men who reported having ever smoked pot had “significantly higher sperm concentration” — precisely 63 million sperm per milliliter of semen — compared to the 297 who have never taken a hit, which averaged 45 million/mL.
