Previous research has shown that marijuana has negative effects on reproductive hormones, ovulation, and semen quality, which was believed to make it harder to conceive. But the new study, which was one of the first to actually test conception rates, found no significant difference among users and non-users.
Many states are legalizing marijuana and it has become less taboo, which has likely influenced people to smoke pot while they’re trying to conceive or during pregnancy, says study author Lauren Wise, Sc.D., a professor in the department of epidemiology at the Boston University School of Public Health. Wise and her team asked people to report how often they’d used marijuana during the two months before conception. But, they didn’t ask about participants' prior smoking habits. So, researchers aren’t sure if chronic use has a different effect on conception compared to acute use.
