Smoking marijuana may not affect mens fertility: Study | #98365

He said: "These unexpected findings from our study highlight that we know too little about the reproductive health effects of cannabis". He's an associate professor of nutrition and epidemiology at the Harvard T.H. Chan School of Public Health in Boston.

"We spent a good two months redoing everything, making sure that there wasn't any error in the data", Cahvarro was quoted by Bloomberg.

Men who smoke marijuana may have higher sperm counts than those who have never used the drug, a surprising new study finds.

The findings are far from conclusive, and more research is needed to understand whether smoking marijuana could indeed, at certain levels, have a positive effect on sperm production.

"An equally important limitation is the fact that most of the data were collected while cannabis was illegal in MA, so it is hard to know to what extent men may have under-reported use of cannabis because of social stigma or potential consequences related to insurance coverage for infertility services", said Dr. Nassan. Since marijuana was still illegal in MA at that time, it's possible that many test subjects under-reported or even lied about their cannabis consumption during the trial.

Dr Chavarro said: "It is well-documented that within normal ranges, high testosterone levels are associated with greater engagement in risk-seeking behaviors, including drug use". For men who smoke marijuana and are planning on having children, the advice keeps getting more confusing. The researchers are quick to point out that despite the seemingly clear results, the research does have its limitations and that smoking pot shouldn't be used as a fertility aid.

For this study, researchers collected 1,143 semen samples from 662 men between 2000 and 2017. In comparison, non-cannabis consuming men averaged sperm concentrations of 45.4 million per milliliter. They provided semen and blood samples, which the researchers analysed for information on sperm and reproductive hormones. The findings held even after the researchers took into account some factors that could have affected sperm concentration, such as age, cigarette smoking and alcohol use. "Secondly, the study is a great opportunity to spark interest on investigating the health effects of marijuana particularly with the backdrop of increasing legalization of recreational use in the US coupled with a greater perception that marijuana poses no health risks".

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 risky than opioids by the USA government remains a roadblock to that research, incidentally).

WEDNESDAY, Feb. 6, 2019 (HealthDay News) - Forget the mellow slacker image - pot smoking might actually make men more potent. It's possible that low levels of marijuana could boost sperm quality, they say, while higher levels and repeated use could have a negative effect. In addition, a study from a year ago found that marijuana's active ingredient, THC, can change the structure and development of a sperm's DNA.

Only five per cent of cannabis smokers had estimated sperm concentrations below 15 million/mL - the World Health Organisation's threshold for "normal" levels.

"An equally plausible interpretation is that our findings could reflect that men with higher testosterone levels are more likely to engage in risk-seeking behaviours, including smoking marijuana", Nassan explained.
