Smoking and reproduction

Abstract

In the Netherlands, approximately 30% of all women of reproductive age smoke, compared with 36% of men.Cigarette smoking is associated in women with a dose-related reduction in fecundity and fertility and in men with a reduction in semen quality. Smoking has a negative effect on pregnancy: increased rates of antepartum bleeding and placenta praevia have been described. Smoking is also associated with increases in the rates of spontaneous abortion, low birth weight and perinatal death. Some tobacco-related perinatal deaths are due to an increased risk of serious malformation. Children of mothers who smoke are admitted twice as often to hospital for pulmonary problems. However, studies on maternal smoking and childhood cancer have proved inconclusive.
