Just about now...: Some studies have shown decreases in the amount of semen, abnormal swimming in sperm, lower testosterone levels, and higher estrogen levels in marijuana users. The studies are not big, so more research is needed. Smoking (inhaling smoke, which is full of lung irritants and cancer-causing chemicals) of any kind is unhealthy but it is unknown if pot users actually have fewer children than non-users.
