Cigarette smoking has been shown to impair fertility in both women and men. Women who smoke have a lower fertility rate, higher miscarriage rates, and deliver smaller weight babies. Data also show that women who smoke while pregnant will affect the fertility of their children. In one study, women who smoke while carrying a female child doom their daughters by lowering their fertility by as much as 50%!
Other studies in women seeking IVF treatment show that women who smoke while undergoing an IVF cycle have a 50% decrease in their chances at getting pregnant compared to age-matched non-smoking women. A decrease is also noted in passive smokers (i.e. if your husband smokes and you do not). Women who do not smoke but cohabit with a partner who does should encourage their partners to start smoking outside the house.
