Cannabis and Sperm


Despite the age-old rumor cannabis does not hinder sperm activity.

Currently, 1 in 6 Canadian couples experiences issues with infertility according to the Government of Canada. With national legal cannabis quickly approaching in the country, it is important that we further understand any possible connection with our ability to conceive children and smoking or ingesting cannabis. That being said, there is a long-standing rumor that cannabis use can decrease sperm count or fertility in some way.

But a new study led by researchers at the Boston University School of Public Health (BUSPH) discovered that cannabis use, both by women and men, doesn’t lower a couple’s chance of getting pregnant. The study was published in the Journal of Epidemiology and Community HealthΒ and is the first of its kind to study a possible connection between cannabis use and fecundability.

The research team focused on 4194 women, 1125 of whose male partners also enrolled. Those surveyed were in monogamous relationships and not using contraception or fertility treatments. They were monitored for a period of three years (between 2013 and 2016). Just 12% of women and 14% of the men surveyed admitted to being cannabis users. After twelve cycles of follow-ups, couples that used cannabis showed the same probability of contraception as those who didn’t use cannabis.

These results should help Canadian legislators understand the effects cannabis may have on the healthcare system by way of fertility treatments. With more scientific research we can hopefully drive more intelligent cannabis legislation across the globe.
