Fewer bubs for potheads: "The use of marijuana by either the man or woman before fertility treatment could reduce the likelihood of success, a study suggests. "If these study findings are confirmed by additional research, we would recommend that physicians tell couples to not use marijuana for at least one year before starting fertility treatment," says Dr Hillary Klonoff-Cohen of the University of California. With colleagues, she investigated the possible effects of marijuana use on the outcomes of 221 couples who underwent in vitro fertilisation (IVF) or gamete intrafallopian transfer (GIFT) treatment for infertility. The findings are published in the American Journal of Obstetrics and Gynecology. At least 10 per cent of men and women smoked marijuana in the year before the fertility procedure, the authors report, and 3 per cent of women and 0.5 per cent of men reported smoking marijuana the day before the procedure. Longer marijuana use over a woman's lifetime reduced the number of eggs that could be retrieved and the number of embryos that could be transferred, the results indicate. Compared with women who didn't smoke marijuana, the researchers note, women who smoked marijuana during the year before the procedure had 25 per cent fewer eggs and about one less embryos transferred."
