Lately, there was an growing curiosity among the many scientific neighborhood to clarify how cannabis impacts male fertility.

This has to do with the truth that the dominant group of cannabis customers continues to be younger and middle-aged males. Principally, males of their reproductive years.

With the legalization of leisure marijuana use in some American states and Canada, there’s a justified assumption that the variety of male pot people who smoke will solely rise within the close to future.

So, what’s the true correlation between cannabis and male fertility? Is weed good or unhealthy for males’s reproductive well being?

Restricted analysis and no straightforward reply

We already know that authorized substances like tobacco and alcohol (and a few unlawful ones, e.g. medicine) have a detrimental impact on each female and male reproductive well being.

One other disturbing truth is that over the previous 40 years, sperm rely per milliliter of semen has declined for an astonishing 40%, or 1% for each passing yr. In the present day’s males are half as fertile as their grandfathers had been.

On this alarming epidemic of male infertility, the place does marijuana stand?

The reply shouldn’t be a straightforward one.

Whereas research about marijuana results on sperm and male fertility have been restricted, some earlier research counsel that cannabis has a damaging influence on sperm high quality.

The outcomes of these research present that cannabis reduces the quantity of seminal fluid, complete sperm rely, and even point out the irregular movement habits amongst remaining sperm cells.

Final yr we wrote about this matter and coated a few of the most distinguished analysis papers that had been out there for the time being. The overall conclusion was that there’s a damaging impact of cannabis use on sperm manufacturing, however solely within the brief run.

In different phrases, weed ought to solely be averted if a person is planning to start out a household. That’s as a result of it takes about three months for every sperm cell to be created. If a person undergoes cannabis abstinence for 3+ months, his new sperm cells shouldn’t be affected by earlier cannabis consumption.

2019, and sudden new findings

Now let’s placed on maintain all that we’ve talked about up to now. In February this yr, a brand new examine by the Harvard T. H. Chan College of Public Well being in Boston was printed within the journal Human Copy. Their findings had been shocking, to say the least.

Opposite to their unique speculation, scientists found that males who smoked cannabis in some unspecified time in the future of their lives had considerably greater sperm concentrations than those that had by no means used marijuana earlier than.

The researchers performed a examine amongst 662 males who had been sufferers on the Massachusetts Normal Hospital Fertility Heart within the interval between 2000 and 2017. All males belonged to {couples} that had an issue with conception and had been in search of assist at a fertility clinic.

On common, the boys had been 36 years previous, non-smokers, largely Caucasians, with a university diploma. All of them offered a complete of 1143 semen samples, whereas 317 males additionally offered blood samples that had been used for the evaluation of the reproductive hormones.

With the intention to collect info on the historical past of marijuana consumption, members had been requested to fill in a self-administered questionnaire.

Greater than half (55%) of the boys reported having smoked marijuana (a minimum of 2 joints) in some unspecified time in the future of their lives. Amongst these members, 44% mentioned that they’d used cannabis up to now, whereas 11% of them categorized themselves as present cannabis customers.

Earlier than conducting an in-depth evaluation, researchers hypothesized that marijuana consumption could be related to worse semen high quality. This was primarily based on earlier analysis findings, though most of these research had been performed on animal fashions or on males with lengthy histories of medication, tobacco, and alcohol use.

Larger sperm rely, decrease FSH

Evaluation of the semen pattern confirmed that males who had smoked marijuana in some unspecified time in the future had notably greater sperm focus and decrease serum FSH focus than males who had by no means used marijuana.

FSH (Follicle-stimulating hormone) is a reproductive hormone that regulates testosterone ranges and helps within the manufacturing of the Sertoli cells which can be important for sperm manufacturing (spermatogenesis) and proper perform of the testicles.

This hormone at elevated ranges could possibly be linked to infertility, so decrease FHS focus typically means an excellent factor for spermatozoids (if not too low).

Jorge Chavarro, affiliate professor of diet and epidemiology at Harvard Chan College of Public Well being and one of many coauthors of this examine, admitted that his staff was actually shocked by the outcomes they bought.

“We spent an excellent two months redoing every little thing, ensuring that there wasn’t any error within the knowledge. We had been very, very shocked about this.” Chavarro mentioned in an interview with Time journal.

Stunning because the outcomes could also be, plainly scientists nonetheless don’t know what to make of them. They’re fairly positive that smoking marijuana shouldn’t be going to treatment your infertility, however it seems that low ranges of marijuana consumption can enhance the perform of the testicles and result in higher sperm and reproductive hormone manufacturing.

In terms of greater doses, marijuana has the utterly reverse impact. This has been supported by all of the earlier research on the subject of marijuana results on sperm.

Probably the most believable clarification of those sudden outcomes is that males who’ve greater testosterone ranges are extra susceptible to risk-seeking habits, which incorporates smoking cannabis for its psychoactive results.

Principally, this could imply that males who have already got higher sperm high quality are likely to smoke extra pot, not the opposite approach round.

No common consensus

Complicated as it could be to have two completely different interpretations of the identical outcomes, the impact of marijuana consumption on male fertility (and physique on the whole) continues to be unclear and there’s no proof that the final consensus might be reached within the foreseeable future.

This simply proves how advanced cannabis and its well being results are, and the way little we find out about this unbelievable plant.

Perhaps it’s higher to depart the ultimate phrase to aforementioned Jorge Chavarro when he says: “We might have discovered what we thought we had been going to search out, and perhaps wouldn’t have been as shocked and would have ended up writing a really completely different paper. However the truth that we confirmed the precise reverse compelled us to look very, very deeply into the marijuana well being results literature. There’s not that a lot. We’re working totally on assumptions and good intentions and hunches.”

Weed and sexual want – the constructive hyperlink all of us knew was there

One other attention-grabbing analysis has been getting nods amongst cannabis customers, and it’s a few constructive hyperlink between weed and sexual want. What many people knew has now been scientifically confirmed. Weed does make you are feeling sexy, and intercourse whereas excessive is usually higher than common one!

A population-based examine, performed by the Stanford College of College Medication, has been printed within the Journal of Sexual Medication (JSM). They used self-report questionnaires to collect knowledge of 28,176 ladies and 22,943 males, all aged between 25 and 45 years previous.

The outcomes confirmed that girls who didn’t use cannabis reported that they’d intercourse six occasions on common up to now 4 weeks. However, ladies who consumed cannabis every day had intercourse 7,1 occasions in the identical timeframe.

The development is comparable for males. Those that don`t smoke weed had intercourse 5,6 occasions within the four-week interval, whereas that determine goes to six,eight for day by day cannabis customers.

What these numbers are actually telling us is that marijuana customers have extra intercourse than those that don`t smoke the plant. And the identical habits goes for all pot customers, no matter their age, intercourse, race, well being, marital or parental standing.

Weed and erectile perform

The same examine was printed in the identical journal in February final yr. Researchers had been looking for the affiliation between marijuana use amongst younger males and their erectile perform.

They performed a survey amongst 1265 sexually lively younger males and located that there’s a statistically important, constructive impact of cannabis use on males’s erectile perform.

However that’s not all. Additionally they found that weed will increase males’s sexual want, orgasmic perform, intercourse satisfaction and their satisfaction on the whole.

Conclusion

Though our present understanding of how marijuana impacts a person’s fertility potential is much from being conclusive, there appears to be sufficient proof to construct a pro-marijuana case in relation to enhanced sexual pleasure.

Figuring out that intercourse could be very useful for total well being, we are able to counsel some average cannabis smoking earlier than intercourse, and you’ll resolve for your self whether or not it’s making you extra relaxed and aroused.
