Physiological Signs of Ovulation and Fertility Readily Observable by Women

Induction of fertility in disorders of ovulation.

Ovulation as a male mating prime: subtle signs of women's fertility influence men's mating cognition and behavior.

Women's reproductive fertility peaks for a few days in the middle of their cycle around ovulation. Because conception is most likely to occur inside this brief fertile window, evolutionary theories suggest that men possess adaptations designed to maximize their reproductive success by mating with women during their peak period of fertility. In this article, we provide evidence from 3 studies th...

Physiological predictors of leptin vary during menses and ovulation in healthy women.

Although research has shown interactions between the reproductive system and energy homeostasis, it is not clear how environmental or behavioral factors may factor into these associations. Here we aimed to determine how changes in reproductive state (i.e., phase of the menstrual cycle) and other behavioral and physiological factors may influence leptin levels in healthy women, as well as how se...

Induction of ovulation and fertility in prepuberal gilts.

This study was conducted to evaluate fertili ty in 160 day-old gilts. In Experiment 1, 28 gilts in the following five groups were injected with (1) vehicle, (2) 500 /ag of a synthetic gonadotropin releasing hormone (GnRH) anal ogne [ D-Ala 6-des-Gly-NH2101 LH-RH-ethylamide (AY 25205), (3) a cbmbination of 400 IU of pregnant mares' serum gonadotropin and 200 IU of human chorionic gonadotropin (4...

Induction of Estrus, Ovulation and Fertility in Prepuberal Gilts

Induction of synchronized estrus and ovulation in prepuberal gilts is utilized in our laboratory to study factors influencing fertility and early embryonic development. Prepuberal females provide an inexpensive source of fertilized eggs, and they are not complicated by the presence of estrous cycles. Thus, estrus inducing treatments can be applied at any time. In the first of four experiments r...
