New Report Says That Marijuana Can Help Treat Male Infertility

Turns out weed can help with a lot of reproductive issues. In research that will appear in this month’s issue of The FASEB Journal, scientists show how a cannabinoid receptor called “CB2” helps regulate the creation of sperm, Top Science reported.

This suggests not just that the drug can disrupt fertility in males, but also that it might help treat male infertility.

To make their discovery, researchers at the University of Rome treated three groups of mice with different agents for 14 to 21 days, according to a release. It added:

“The first group was treated with a specific activator of the CB2 receptor. The second group was treated with a specific inhibitor of the CB2 receptor. The third group received only a saline solution and served as the control group. The group treated with the CB2 activator showed an acceleration of spermatogenesis, while the group treated with the inhibitor displayed a slower rate of the process. This suggests that a tight balance of CB2 activation is required for the proper progression of spermatogenesis.”

In other words, adjusting CB2 can lead to changes in sperm generation, and potentially help treat male infertility. “The possibility to improve male fertility is one of the main focuses of this study, since infertility is a worldwide problem that affect up to 15% of couples in which male factors account for almost 20-70%,” researcher Paola Grimaldi said.
