A new study out of Harvard may negate the idea that marijuana is harmful to reproductive health in men.
Harvard researchers found that men who smoked marijuana had a higher sperm count than non-smokers.
The study, published Wednesday, collected 1,143 semen samples from 662 men between 2000 and 2017.
They found that 365 men in the group that smoked marijuana in the past had higher amounts of sperm than the remaining 297 men in the study who had never used marijuana before.
Recent studies in the past claimed that marijuana potentially caused genetic changes in sperm and affect male fertility.
Researchers say it’s too early to determine if smoking marijuana can have a positive effect on sperm count.
