Marijuana Use and Time to Pregnancy

Fertil Steril; ePub 2018 Mar 16; Kasman, et al

Neither marijuana use nor frequency of marijuana use is associated with time to pregnancy for men and women, a recent study suggests. The retrospective review of cross-sectional survey data included male and female respondents aged 15 to 44 years who participated in the 2002, 2006-2010, and 2011-2015 National Survey of Family Growth. The primary outcome was estimated time to pregnancy. Researchers found:

  • 758 males and 1,076 female participants responded that they were actively trying to conceive.
  • Overall, 16.5% of men reported using any marijuana while attempting to conceive vs 11.5% of women.
  • The time ratio to pregnancy for never smokers vs daily users of marijuana in men was 1.08 and in women 0.92, which was not statistically significant.
