Does Marijuana cause Erectile Dysfunction?

The facts and myths

Marijuana lowers hormone levers:  Unclear

Studies have shown booth positive and negative results. A Buffalo study showed marijuana causing harm to sperm and a University of Iowa study showed no harm.  At this point it seem that it may depends on an individuals own body and his reaction to the chemicals in Marijuana.

According to the report made by Buffalo University scientists, men who smoke weed have much less seminal fluid than those who don’t use drugs.

Researchers suggest that marijuana is doing something to sperm that have a lower count and swim way too fast burning out before reaching the egg. It is known that marijuana contains different chemicals that can affect human physiology. This drug has an impact on tetrahydrocannabinol or THC that can disrupt the way sperm goes.

Men’s sperm has receptors which can be stimulated by THC. Tests have revealed that sperm influenced by smoking marijuana swims in a strange fashion. It is less able to attach to the egg.

More than 20 men who had used cannabis twice a day for at least 5 years in a row participated in the research. Their sperm samples were tested. It turned out that the sperm swam too fast too soon. And this reduced the chances of sperm reaching the testicles.

A permanent use of marijuana can burnout your sperm before it reaches the egg. As the result men’s capability of fertilization might be impossible.

Dr. Robert Block at the University of  Iowa disputes the myth.  The U. of Iowa study found that chronic marijuana use had no effect on testosterone, luteinizing hormone, follicle stimulating hormone, prolactin and cortisol in men or women. Noting that six other studies had failed to show lowered testosterone levels in men, Dr. Block concluded: “It appears that marijuana, even heavy use of the kind that’s typical in the United States, doesn’t alter testosterone levels.” However, he cautioned that heavy use might have other adverse effects, including “possible effects on reproductive function and mild, selective cognitive impairments associated  with heavy, chronic use.” Block’s study is published in Drug and Alcohol Dependence, Vol. 28: 121-8 (1991)

A animal studie of cannabinoids in male mice: effects on fertility and spermatogenesis. By S Dalterio, F Badr, A Bartke, and D Mayfield (1982)  showed that oral administration of THC (delta 9-tetrahydrocannabinol) had a biphasic effect on plasma testosterone concentrations in male mice, causing rapid sustained increases at low doses and subsequent decreases at higher doses. In hypophysectomized and intact mice receiving gonadotropins (human chorionic gonadotropin), treatment with delta 9-tetrahydrocannabinol maintained higher plasma testosterone concentrations. Thus, this cannabinoid may interact with gonadotropin and directly influence testicular steroidogenesis in vivo

In 1974, researchers reported diminished testosterone, reduced sexual function and abnormal sperm cells in males identified as chronic marijuana users. 34 In a laboratory study, the same researchers reported an acute decrease in testosterone, but no chronic effect after nine weeks of smoking; they did not evaluate sperm volume or quality. 35 In other laboratory studies, researchers have been generally unable to replicate these findings, 36 although by administering very high THC doses – up to 20 cigarettes per day for 30 days – one study found a slight decrease in sperm concentrations. 37 In all studies, test results remained within normal ranges and probably would not have affected actual fertility.


One response to “Does Marijuana cause Erectile Dysfunction

  • Reggie Lebold

    Of all conditions affecting today’s male, erectile dysfunction or impotence is the one of the commonest and yet most discreet. No man will ever tell you that he is suffering from erectile dysfunction. Why? A man’s masculinity is usually determined by his success, potency and virility. Erectile dysfunction is thought to be a hindrance to all three since it affects his ability to have children and to perform. Shame and inadequacy overshadows his logic and become his constant companions. Man feels incomplete if he cannot even produce an erection..
