Surprisingly a new study has found that smoking marijuana can lead to a better sperm count for men.
The study, which was published this month in the journal Human Reproduction, found that men who smoke marijuana have higher sperm counts than those who have never used the drug.
The researchers have pointed out that the findings are not “consistent” with previous research that has been done. The findings are also far from conclusive.
Study senior author Dr. Jorge Chavarro, an associate professor of nutrition and epidemiology at the Harvard T.H. Chan School of Public Health in Boston, stated, “We know a lot less than we think we know.”
As part of the study, the researchers analyzed information from 662 men. The men and their partners were evaluated for infertility from 2000 to 2017 at the Massachusetts General Hospital Fertility Center. The men offered blood samples and answers questions about how often they smoked marijuana or used other drugs.
55% of the men reported ever smoking marijuana in their lifetimes, and 11% said that they currently smoked marijuana.
Men who had reported ever having smoked marijuana had an average sperm concentration of 63 million sperm per milliliter of semen, compared with 45 million sperm per milliliter of semen among those who had never used marijuana.
“Our findings were contrary to what we hypothesized at the start of the study,” stated study lead author Feiby Nassan, a postdoctoral research fellow at the Harvard T.H. Chan School of Public Health.
