Invited Commentary: The Association Between Marijuana Use and Male Reproductive Health.

Abstract

Approximately 15% of all couples are unable to conceive after a year and are labeled infertile. In recent years, increasing attention has been given to lifestyle factors that may impact fertility. In the United States, it is estimated that there are more than 17 million current users of marijuana with 4.6 million using marijuana almost daily. Although common, to date, little data exist on the impact of marijuana use on male fertility. In the current issue of the Journal, Gundersen et al. (Am J Epidemiol. 2015;182(6):473-481) provide data examining the relationship between marijuana use and semen quality from young men recruited out of the general Danish population. Men who reported daily marijuana use displayed significant lower sperm concentration and sperm counts compared with nonusers, while testosterone levels were higher. The current report provides important information for patients and providers regarding the negative association of marijuana use on semen quality. Although the benefit of marijuana cessation on recovery is uncertain, further study on the impact of marijuana use on male reproductive health is warranted as more states explore marijuana legalization.
