If you've been confused by the facts surrounding the impact smoking weed can have on a man's sperm count, you're not alone. Here's what experts are saying. Marijuana use in America is clearly booming—10 states have made its use legal, and 9 more states projected to make it legal in With its popularity gaining, research on marijuana's health benefits and risks have become robust. And when it comes to fertility, it's become a hotly debated and studied topic to learn about its impacts on sperm and sperm health. Is marijuana use good or bad for sperm?
Marijuana Use May Lower Sperm Counts 'Quite a Lot' | Live Science
The prevalence of marijuana use among males of reproductive age has never been higher, while male factor infertility is also on the increase. Researchers believe that the spread of legal medical and recreational marijuana use in the U. Marijuana contains the cannabinoid drug THC tetrahydrocannabinol , its primary psychoactive chemical, as well as other cannabinoids. Several studies have linked marijuana usage and male infertility but how the use of the drug affects infertility has been attributed to a variety of reasons. One study found that men who smoke marijuana frequently have significantly less seminal fluid, a lower total sperm count and their sperm behave abnormally. All of these factors could adversely affect fertility. The University at Buffalo study was the first to exam marijuana's effects on the specific swimming behavior of sperm from marijuana smokers and to compare the results with sperm from men with confirmed fertility.
Does Marijuana Affect Sperm Count and Male Fertility?
The unexpected finding that men with a history of cannabis smoking had higher sperm counts has been widely reported after it was published in a leading fertility journal. Around half of men had tried, or currently used, cannabis and the researchers found just 5 per cent had clinically low sperm counts, compared to 12 per cent of those who had never tried it. The authors suggest that this could be a result of cannabis on the body's endocannabinoid system which sends chemical messages in the brain and has been associated with regulating fertility. Professor Sheena Lewis, from Queen's University Belfast, said her lab had studied the effects of cannabis use at similar levels reported by the Harvard team. However, he said he was "unconvinced" by the prospect of cannabis being a pancea for male ferility problems.
Men who smoke marijuana may have higher sperm counts than those who have never used the drug, a surprising new study suggests. The findings are "not consistent" with previous research, which has suggested that marijuana has a harmful effect on men's testicular function, the researchers said. However, the study, published in the Feb. The findings are far from conclusive, and more research is needed to understand whether smoking marijuana could indeed, at certain levels, have a positive effect on sperm production. But the study does highlight how little researchers know about the effects of marijuana on reproductive health, study senior author Dr.
