Smoking Marijuana Linked to Better Sperm Counts in Surprising Study

'Moreover, nor does it give support to any apparent fertility benefits of smoking marijuana.

A 2015 study found that Danish men who smoked marijuana a couple of times a week had lower sperm counts.

Whether those changes can be passed on to a child remains unknown, but for now, some researchers are warning that men in their childbearing years should consider how weed might impact their fertility and possibly their offspring.

Nevertheless, because much of this research is based on animal models and those with histories of drug abuse, the average pot smoker still can't be sure there's anything sinister to worry about.

However, it's unclear whether using cannabis helps or hinders a man's chances of conceiving.

The results were surprising - and show how much more there is to learn about the link between marijuana use and fertility, the scientists said.

The researchers have cautioned that there are limitations to the findings, as some of the participants may have under-reported their cannabis use.

The researchers also took blood samples from 317 of the men to assess their hormone levels and found that marijuana smokers had higher levels of testosterone.

Just over 50 per cent of the men reported using cannabis; half of these men reported using it in the past, while 11 per cent said they were current users.

In addition, Gianluca de Ficchy added that uncertainty over Brexit has not helped the firm "plan for the future". Nissan had been making the cars in sunderland since 1986 and it has nearly 7,000 people employed there.

As the researchers hypothesized that marijuana smoking would be associated with poorer semen quality, they were surprised to find that men who had smoked marijuana at some point in their lives actually had a higher average sperm concentration - 62.7 million sperm per ml of ejaculate - than men who had never smoked, who had an average concentration of 45.4 million sperm per ml of ejaculate.

Researchers have investigated whether using cannabis affects a man's fertility.

Jorge Chavarro, study author and associate professor of nutrition and epidemiology at Harvard Chan School, commented: "These unexpected findings highlight how little we know about the reproductive health effects of marijuana, and in fact of the health effects of marijuana in general".

He said: "These unexpected findings from our study highlight that we know too little about the reproductive health effects of cannabis".

There's definitely a few caveats to take into account here. Or maybe the relationship between the two is more complicated than it looks on the surface.

"The relations we see between cannabis smoking, sperm counts and testosterone levels are because men with higher testosterone, within normal levels, have higher sperm counts and are more likely to smoke cannabis", she said.

Lawmakers have become a lot more chill about marijuana recently.

What's more, those who had never smoked pot were more likely to fall into the extremes. So the comparison in sperm counts between reported users and non-users isn't necessarily 100 per cent accurate.

None of these limitations or considerations invalidate study's findings, it's just a sign, as Chavarro said, that we need to study cannabis more (the fact that cannabis is still considered more unsafe than opioids by the USA government remains a roadblock to that research, incidentally).
