Investigators at Boston University's School of Public Health evaluated the association between female and male use of marijuana and fecundability (the probability of conception) in 1,125 couples over a period of four years.
Researchers reported that conception probabilities did not differ among couples who used cannabis versus those who did not. "In this preconception cohort study, there was little overall association between female or male marijuana use and fecundability," authors concluded.
