The use of marijuana's by couples, or any one partner before fertility treatment could greatly reduce the success of the procedure. This was found according to new studies when compared to couples that did not use it, marijuana is also popularly called as grass.
Dr Hillary Klonoff-Cohen of the University of California stated that if the studies were confirmed with further investigations then they would recommend that the doctors advice the couples not to have marijuana for atleast one year before starting the treatment.
The doctor and her colleagues investigated the effects of grass on 221 couples that underwent in vitro fertilisation (IVF) or gamete intrafallopian transfer (GIFT) treatment for infertility. The study showed that 10% of men and women smoked marijuana in the year before the fertility procedure, and 3% of women and 0.5% of men reported smoking it the day before the procedure.
The group also found that if the man or the woman had ever used marijuana, their infant had a significantly lower birth weight, as compared with couples that had never used marijuana. This effect seemed to increase with higher or more recent marijuana use. Marijuana has been implicated with low birth weight, although the results are inconsistent, she stated. However, she also said that this are the initial reports and that their findings need to be verified by larger studies.
