Marijuana use—by either men or women—does not appear to lower a couple’s chances of getting pregnant, according to a new study led by Boston University School of Public Health (BUSPH) researchers.
The study, published in the Journal of Epidemiology and Community Health (JECH), was the first to evaluate the link between fecundability—the average per-cycle probability of conception—and marijuana use.
About 15 percent of couples experience infertility. Infertility costs the US healthcare system more than $5 billion per year, and thus identifying modifiable risk factors for infertility, including recreational drug use, is of public health importance. Marijuana is one of the most widely used recreational drugs among individuals of reproductive age. Previous studies have examined the effects of marijuana use on reproductive hormones and semen quality, with conflicting results.
