From the article:

“The effect of cigarette smoking on the ovaries has been known for a while, she said. “There’s often ovulatory dysfunction in heavy smokers, and they tend to have menopause at an earlier stage,” Wu noted.The authors of the study looked retrospectively at 741 non-heavy smokers (under 10 cigarettes a day) and 44 heavy smokers (over 10 cigarettes a day). All of the women had received oocyte donations as part of in vitro fertilization (IVF) between January 2002 and June 2005.

None of the women’s partners smoked and none of the oocyte donors were heavy smokers.

According to the study, the lighter smokers had a significantly higher pregnancy rate (52.2 percent) than the heavy smokers (34.1 percent).

The fact that the oocytes were donated means the problem lies with the uterus, not the ovaries, the researchers noted.”
