Male cannabis use before conception could double the risk of miscarriage, according to Boston University School of Public Health (BUSPH) research presented at the 75th Scientific Congress of the American Society for Reproductive Medicine on October 14.
The research is pending peer review and publication, but is the first study to link male cannabis use and pregnancy issues. Previous research has suggested that frequent cannabis use reduces semen quality.
“This is just one study, and more research is needed before any concrete recommendations for couples are made,” says BUSPH doctoral candidate Ms. Alyssa Harlow, who led the study. “It’s important that we continue to do research that helps us better understand the health impact of cannabis, including on our reproductive health, so that couples can make informed decisions.”
Ms. Harlow and colleagues used data from the BUSPH-based Pregnancy Study Online (PRESTO) of over 1,400 couples throughout North America. Couples who are trying to conceive answer a variety of questions as part of PRESTO — including questions about behaviors such as cannabis use — every two months until conception and then at various stages of pregnancy.Friday Letter Submission, Publish on November 01
