Can smoking marijuana affect female fertility?

Yes: Research shows that steroid hormones, cytokines, and the endocannabinoid system (ecs) in the central nervous system are closely related in female fertility. Any disruption in this system (like from external smoked thc, stored in fat) can result in fetal loss. Use of marijuana is associated with implantation failure, spontaneous miscarriage, fetal growth restriction and premature birth in humans.
