Your parents may have given you many reasons not to try the drug. Most of them are likely to be very wise and should be listened to carefully. But an old excuse has just been broken. A new Harvard study has shown that smoking marijuana increases sperm count in men.

The team of researchers led by the Harvard T.H. School of Public Health Chan collected sperm samples of 662 men between 2000 and 2017, an average age of 36 years. Volunteers were asked if they had ever smoked more than two joints or as much marijuana in their lives and they were smokers.
Smokers have higher sperm counts
Fifty-five per cent of men reported having smoked marijuana, of which 44% in the past and 11% among current consumers. The surprising results of the study indicated that marijuana smokers had a higher sperm count than men who had never used this drug.
Drug users recorded an average of 62.7 million spermatozoa per millimeter, compared to 45.4 million sperm for sober men. In addition, only 5% of marijuana smokers had a sperm count below the level deemed healthy by the World Health Organization, compared with 12% of non-smokers.
More testosterone related to drug use
Blood tests of subjects were also recorded, with smokers recording higher testosterone levels than their counterparts. Researchers are quick to point out that, despite seemingly clear results, research has its limits and that smoking should not be used as a fertility aid. There is other research that has shown that drug use is related to infertility.
"These unexpected discoveries show how little we know about the effects of marijuana on reproductive health, and indeed, on its effects on overall health," said the study's co-author. , Jorge Chavarro. "Our results should be interpreted with caution, and they emphasize the need to further study the effects of marijuana use on health."
The study has flaws but provides a starting point
A key aspect of the study is that men reported their drug use, which makes it difficult to understand the doses. The men used in the study were also enrolled in fertility clinics and were all white men graduating from the university. The study should be redone using a larger sample of participants to achieve truly scientifically sound results.
"Our findings are contrary to our original badumptions," said lead author Feiby Nbadan. , which is known to play a role in fertility, but these benefits are lost with higher levels of marijuana use. "
"An equally plausible interpretation is that our findings may reflect the fact that men with higher testosterone levels are more likely to engage in risk-seeking behaviors, including smoking marijuana," she said. he continued.
The team summarizes their research by claiming that it may be true that moderate marijuana use may improve testicular function, but that any benefit may disappear at higher doses. In conclusion, smoking pot will not make you a machine to make babies, but a little bit could help you get started.
