UCLA researchers Martie Haselton and Christina Larson review their study that identifies ways in which women's behavior toward their mates changes as they approach ovulation.

Long after women have chosen Mr. Stable over Mr. Sexy, they struggle unconsciously with the decision, according to a new study by UCLA researchers who look at subtle changes in behavior during ovulation.

At their most fertile period, these women are less likely to feel close to their mates and more likely to find fault with them than women mated to more sexually desirable men, the research shows.

"A woman evaluates her relationship differently at different times in her cycle, and her evaluation seems to be colored by how sexually attractive she perceives her partner to be," said Martie Haselton, a professor of psychology and communication studies at UCLA and senior author of the study.

Nevertheless, the negative feelings appear fleeting, and they don't seem to affect a woman's long-term commitment to her romantic relationship, the study found.
