A new mice study shows that chronic exposure to CBD resulted in DNA fragmentation and motility impairment in the animals’ sperm.
Investigators point out, however, that both groups of mice experienced slower average path velocity of the sperm.
“Chronic exposure to CBD changed the dynamics of spermatogenesis,” the study notes, adding that chronic exposure “induced DNA fragmentation and impairment of motility” in mice sperm.
All that said, “the weight of reproductive organs, sperm count and hormone levels were not affected by CBD treatment,” study authors write.
A study published in June suggests that using weed “may have a detrimental effect on semen quality, particularly morphology and volume.” That being the case, researchers noted THC “can alter signalling pathways within spermatozoa, affecting spermatogenesis and fertility.”
And another study out of Duke University found that sustained cannabis abstinence could significantly lower its negative effects
