Sperm From Marijuana Smokers Move Too Fast Too Early, Impairing Fertility

Men who smoke marijuana (cannabis) frequently have significantly less seminal fluid, a lower total sperm count and their sperm behave abnormally, all of which may affect fertility adversely.

The Study was first conducted at the department of reproductive physiology at the University at Buffalo 2003.

Marijuana contains the cannabinoid drug THC (tetrahydrocannabinol), which is its primary psychoactive chemical, as well as other cannabinoids.

 “The bottom line is, the active ingredients in marijuana are doing something to sperm, and the numbers are in the direction toward infertility,” said Lani J. Burkman, Ph.D., lead author on the study. Burkman is assistant professor of gynecology/obstetrics and urology and head of the Section on Andrology in the UB School of Medicine and Biomedical Sciences. UB’s andrology laboratory also carries out sophisticated diagnosis for infertile couples.

Men involved in actively trying to concieve a child should avoid THC, probably for at least a month prior to TTC.
