A history of marijuana use among men and women is not associated with compromised effects on IVF (in vitro fertilization) outcomes, according to data published in the Journal of Cannabis Research.

A team of researchers from Canada and Israel assessed IVF treatment outcomes among male-female, non-donor IVF patients that were either cannabis users or non-users.

Authors reported: “Our study did not show any detrimental impact of current cannabis use on any of the measured IVF outcomes. … All the reproductive outcomes of cannabis users and non-users in our study were comparable. These parameters included measures of ovarian response, sperm quality, efficiency of fertilization, early embryonic development, and implantation. In fact, the ongoing pregnancy rate per cycle start trended higher for the group of cannabis users (35.2 percent vs. 29.1 percent). This could partially relate to the female participants in the user group being younger than the non-user counterparts.”

They concluded, “The results of this study are in line with the newer studies suggesting that the use of cannabis is not associated with a compromised outcome for couples undergoing IVF.”

Other recently published studies have affirmed that a history of cannabis use does not negatively impact fertility rates in either men or women, nor does it adversely impact overall reproductive health in men.
