Can marijuana cause fertility problems?
According to the National Academy of Sciences’ Institute of Medicine’s 1999 report, Marijuana and Medicine: Assessing the Science Base: “[T]he effect of cannabinoids on the capacity of sperm to fertilize eggs is reversible and is observed at [concentrations] which are higher than those likely to be experienced by marijuana smokers … The well-documented inhibition of reproductive functions by THC is thus not a serious concern for evaluating the short-term medical use of marijuana or specific cannabinoids.”
