A new study from Duke Health finds that THC affects epigenetics changing the DNA of sperm in men of child-bearing age.
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.”
A new research from the United Kingdom finds that going for a walk three times a week can boost men’s fertility.
For their study, the researchers took 261 healthy men aged from 25 to 40 who previously performed some exercise. The first group performed moderate exercises (walking or jogging on a treadmill for 25-30 minutes per day, 3-4 times a week) over 24 weeks. The scientists compared this group to two other groups that were exercised more intensively, and to one that didn’t perform any physical activity.
The findings of the research show that all men who exercised had improved sperm but those who were in a group with moderate exercises, showed the best results. Their volume of sperm rose by 8.3% compared to men who didn’t exercise.
