There’s certainly no Harvard-approved medical recommendation to smoke weed as a fertility treatment but this study, at least, suggests that a little marijuana doesn’t hurt.
Researchers at Harvard University have found evidence that marijuana, which was once demonised for causing negative effects on male fertilityas, is actually associated with higher sperm counts. The finding contradicts all conventional mainstream thinking on how weed affects sperm.
The study, which was published in the journal Human Reproduction analysed 1,143 semen samples from 662 men collected between 2000 and 2017 at the Fertility Clinic at Massachusetts General Hospital. They found that those who had smoked weed at some point in their life had a mean sperm concentration of 62.7 million sperm per milliliter (mL) of ejaculate, while men who’d avoided marijuana entirely had mean concentrations of 45.4 million/mL.

Although this may be great news for weed smokers, the participants are not necessarily representative of the general population. Further research must be conducted and include a wider variety of the population. Those involved in this particular study were predominantly white, college educated men, all seeking treatment for fertility at a centre.
The authors of the study do have some theories behind the increased sperm count of marijuana users. One is that low levels of marijuana could have a positive effect on the endocannabinoid system, the neurotransmitters in the nervous system that bind to cannabinoid receptors, and are known to affect fertility. Again, without further research, this is just a theory at the moment.
As more and more people are coming to realise the benefits associated with the plant, we can see more research being conducted that supports what smokers have been telling us for years – “its all good maaan”.
