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 Spanish study that eating a handful of nuts, such as almonds, hazelnuts, and walnuts, improves the sperm count by 16%. Also, nuts boost sperm movements by 6%, its survival by 4% and shape by 1% that are all related to male fertility.
For the study, a team of researchers from the University Rovira I Virgil, Tarragona, Spain, analyzed 119 healthy men aged between 18 and 35 years for 14 weeks. The results of the analysis showed that a handful of nuts on a daily basis reduces sperm’s DNA damage.
Author of the study Dr. Albert Salas-Huetos says: “Evidence is accumulating that healthy lifestyle changes such as following a healthy dietary pattern might help conception and of course, nuts are a key component of a Mediterranean healthy diet.”
The findings of the study were presented at the European Society of Human Reproduction and Embryology in Barcelona, Spain.
A new study from Denmark shows that such widespread painkiller as ibuprofen can have a significant negative effect on male fertility affecting testicular health, altering hormone production and inducing compensated hypogonadism.
For the research, the scientists recruited 31 men aged between 18 and 35 half of whom received a moderate dose (600 mg, or three tablets) of the drug daily during six weeks. The other group received placebo. Within 2 weeks, the men who were taking ibuprofen on a daily basis demonstrated an increase in luteinizing hormones.
The team writes in their paper: “It is also of concern that men with compensated hypogonadism may eventually progress to overt primary hypogonadism, which is characterized by low-circulating testosterone and prevalent symptoms including reduced libido, reduced muscle mass and strength, and depressed mood and fatigue.”
