However, that doesn't mean that smoking weed can help couples get pregnant. Men concerned about their fertility are often warned away from marijuana use, which has been linked to lower sperm counts in previous research. The study also found that there was no significant difference in sperm concentrations between current and former marijuana smokers, and that—among marijuana smokers—greater use was associated with higher testosterone levels in the blood.
Men who have smoked marijuana may be more fertile than those who have never touched it, suggests a new study published in the journal Human Reproduction. While research about marijuana and fertility is limited, some past papers have suggested that it might harm semen quality. Cigarette smoking is also known to be a risk factor for both female and male infertility.
A total of 1, young Danish men aged 18—28 years were recruited between and when they attended a compulsory medical examination to determine their fitness for military service. The participants delivered a semen sample, had a blood sample drawn, and underwent a physical examination. They responded to questionnaires including information on marijuana and recreational drug use during the past 3 months no use, use once per week or less, or use more than once per week.
Just a couple of joints a week could be enough to lower sperm counts by almost a third, even when accounting for other lifestyle factors, recent research shows. The weight of the evidence is that mar is probably a negative impact not only for sperm counts but sperm function. After a slew of headlines this summer about the decline in sperm counts and Western fertility, there has been much handwringing over lifestyle factors.
We know about the harmful effects of drinking while pregnantbut what about drinking before pregnancy? And how does drinking affect male fertility? Is it a big deal?
Evidence suggests the psychoactive ingredient in the cannabis plant— tetrahydrocannabinol THC —activates cannabinoid receptors in a system in the body which includes the internal reproductive organs, explained scientists who presented existing studies on potential harm caused by the drug in the Canadian Medical Association Journal. Using weed is thought to reduce sperm count, for instance. One study involving 1, men found that individuals who smoked marijuana more than once a week in the past three months saw a cut in production of the total sperm count of 29 percent.
If you've been confused by the facts surrounding the impact smoking weed can have on a man's sperm count, you're not alone. Here's what experts are saying. Marijuana use in America is clearly booming—10 states have made its use legal, and 9 more states projected to make it legal in
The prevalence of marijuana use among males of reproductive age has never been higher, while male factor infertility is also on the increase. Researchers believe that the spread of legal medical and recreational marijuana use in the U. Marijuana contains the cannabinoid drug THC tetrahydrocannabinolits primary psychoactive chemical, as well as other cannabinoids.
As recent research shows, men in Western countries are facing a fertility crisis. Sperm count in males of reproductive age more than halved between and For this reason, researchers have been looking at how different modifiable factors, such as lifestyle choices, might affect male fertility.
Literature research results are available from the authors on reasonable request. In recent decades, the decline in human fertility has become increasingly more worrying: while therapeutic interventions might help, they are vexing for the couple and often burdened with high failure rates and costs. Prevention is the most successful approach to fertility disorders in males and females alike.
