Smoking weed could be bad for your sperm. Or, if you’re the proud owner of a vagina, smoking weed could be bad for your boyfriend’s sperm.
According to a recent study by lab-coat-wearing scientists at the University of Sheffield, smoking marijuana can lead to sperm abnormalities that hinder male fertility.
So what does abnormal sperm actually look like? They’ve got oddly shaped heads and poorly developed tails. These guys find it hard to swim upstream, which reduces the odds of making a baby.
Doctor Allan Pacey, the guy in charge, reckons that they didn’t begin the study with a cannabis focus, but the results stood out from the rest. “We were interested in trying to best define the risks of sperm quality. We recruited guys, who gave us a sperm sample and allowed us to investigate aspects of their lives,” he said. “It was just one of the things we asked if they did; it was no more detailed than that.”
The study found that men who were under 30 and fell into the abnormal sperm category were more likely to have smoked pot than their friends with normal sperm. “We found that cannabis doubled the risk of men under 30 having poor sperm," said Pacey. "Statistically it jumped out of the analysis. I think it’s a real effect, and it’s not been shown before in such a robust way.” There is no doubt that marijuana use has an effect on sperm, however the study was unable to pinpoint exactly why.
