Cannabis use medically and recreationally has grown significantly over these last 20 years and researchers felt it was important to find out if using cannabis has any impact on a man or woman's fertility. The recent study involved over 4,000 woman and 1,000 men between the ages of 21 and 45 who were not using contraception. After 12 months of follow ups the amount of participants who used cannabis and those who did not remained at similar rates of conception, meaning cannabis was not a factor in the ability to get pregnant.
The researchers found that during the period from 2013 through 2017, approximately 12 percent of female participants and 14 percent of male participants reported marijuana use in the two months before completing the baseline survey. After 12 cycles of follow-up, conception probabilities were similar among couples that used marijuana and those that did not.
