As it is known not only cigarette smoking harm the health the pregnant women’s health but also second-hand smoking. But a new study shows that women who have been around smokers may have more difficulty getting pregnant than those who have not. A lot of studies have shown that pregnancy complications are common for women who smoke during pregnancy, but less is known about the dangers of second-hand smoke to women who may become pregnant.

In a new study, scientists found that women who had been raised in smoking households were more likely to report having difficulties becoming pregnant. The scientists analyzed nearly 4,800 women who’d visited the University of Rochester’s Roswell Park Cancer Institute between 1982 and 1998 for a health screening, and had been pregnant at least once. At the end of the study they found that women who had been exposed to second-hand smoke during childhood and into adulthood were 39 percent more likely to suffer a miscarriage, and were 68 percent more likely to have problems becoming pregnant. The risk of these problems was tied to the number of hours per day that a woman was exposed to second-hand smoke.

Luke J. Peppone, lead researcher from the University of Rochester, New York, said: "We all know that cigarettes and second hand smoke are dangerous. Breathing the smoke has lasting effects, especially for women when they're ready for children."
