Rogers ML, et al. - A systematic review is performed to survey and synthesize the current literate pertaining to male infertility and cannabis use. There is limited information on the clinical effects of cannabis utilization and the effect on male factor infertility. The small amount of information available suggests that cannabis has a negative impact on male reproductive health. Given the current climate where marijuana is becoming increasingly legalized and the paucity of data of its effects on reproductive health, it is important future research concentrates on this clinical question and that providers and societies actively engage in disseminating this data to the public.
