Effects Of Cannabinoids On Sperm Morphology

Retrieved March 5, from They responded to questionnaires including information on marijuana and recreational drug use during the past 3 months no use, use once per week or less, or use more than once per week. Our findings are of public interest as marijuana use is common and may be contributing to recent reports of poor semen quality. Sperm take about 70 days to mature and then, if not ejaculated, will die shortly after that and be reabsorbed into the body. Materials provided by Duke University Medical Center.

Marijuana use is linked to lower sperm concentrations

And a new study finds regular marijuana may — similar to alcohol and tobacco — affect a man's sperm count and vitality. The study defined regular users as those who smoked marijuana at least weekly for the previous six months. THC is the compound in marijuana responsible for the drug's high. The participants delivered a semen sample, had a blood sample drawn, and underwent a physical examination. THC appeared to impact hundreds of different genes in rats and humans, but many of the genes did have something in common -- they were associated with two of the same major cellular pathways.

Description: As with sperm count, the higher the concentration of THC in the men's urine, the more pronounced the epigenetic changes to their sperm were. Previous studies have hinted that smoking marijuana can lower sperm count, that is, the number of sperm in semen when ejaculated. On average, the sperm concentration in the semen of the 12 non-smokers in the study was about twice as high as it was in the 12 smokers, the study revealed. THC appeared to impact hundreds of different genes in rats and humans, but many of the genes did have something in common -- they were associated with two of the same major cellular pathways. The study was a starting point on the epigenetic effects of THC on sperm and is limited by the relatively small number of men involved in the trial, Murphy said. They also hope to test the umbilical cord blood of babies born to fathers with THC-altered sperm to determine what, if any epigenetic changes, are carried forward to the child. Nevertheless, damaged sperm from marijuana use could theoretically adversely affect the offspring, "assuming that said sperm is viable, capable of fertilization and results in a viable embryo," Murphy added. Marijuana smokers had higher levels of testosterone within the same range as cigarette smokers.
