usage of THC affects sperm

Similarly to previous research where the scientists showed that tobacco smoke, pesticides, flame retardants and even obesity can alter sperm, the new study demonstrates THC also affects epigenetics, triggering structural and regulatory changes in the DNA of users' sperm.

Scott Kollins, Ph.D., professor in psychiatry and behavioral sciences at Duke and senior author of the study, explains: “What we have found is that the effects of cannabis use on males and their reproductive health are not completely null, in that there's something about cannabis use that affects the genetic profile in sperm. We don't yet know what that means, but the fact that more and more young males of child-bearing age have legal access to cannabis is something we should be thinking about.”
