Smoking

Most smokers know that tar, nicotine and the more than 100 other chemicals in cigarettes present a formidable threat to overall health, but scientists now believe that smoking may impair fertility by as much as 30%. Though some of the fertility-related effects of smoking are irreversible, the good news is that "kicking the habit" now can prevent further reproductive damage. 

If you're a smoker who's trying to conceive, you're not alone. Research indicates that, worldwide, about one-third of reproductive age women are smokers. According to the American Society for Reproductive Medicine, nicotine and other toxic chemicals in cigarettes impede fertility by interfering with the body's ability to make estrogen, a hormone integral to regular ovulation, and can make women's eggs more vulnerable to genetic abnormalities. Health care professionals say the degree of reproductive damage caused by smoking appears to be related to the amount and length of time a woman has smoked. 

Some of the ways smoking can undermine female fertility:
  • Restricted blood flow to the genitals, contributing to vaginal dryness and other sexual problems.
  • Decreased egg counts due to destruction of eggs in the ovaries before the eggs reach maturity.
  • Alterations in the release of hormones.
  • Decreased fallopian tube motility and tubal disease.
  • Decreased ability of an embryo to implant.     
Women who want to maximize their overall health while they're trying to conceive can choose from a variety of smoking cessation methods, including support groups, acupuncture, hypnotherapy, nicotine patches and chewing gum. Your fertility specialist can help you choose the method most compatible with your course of treatment. Your effort to conceive should work as an extra incentive to stop smoking before you become pregnant.
