We analyzed the relation between lifetime ovulatory cycles, anovulatory factors, and ovarian cancer risk, using data from 2 Italian studies, including 1822 histologically confirmed cases and 4631 controls. Lifetime ovulatory cycles were inversely related to ovarian cancer risk. Pregnancy and oral contraceptive use had a stronger protective effect than other anovulatory factors.

Abstract
We analyzed the relation between lifetime ovulatory cycles, anovulatory factors, and ovarian cancer risk, using data from 2 Italian studies, including 1822 histologically confirmed cases and 4631 controls. Lifetime ovulatory cycles were inversely related to ovarian cancer risk. Pregnancy and oral contraceptive use had a stronger protective effect than other anovulatory factors.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
