In this paper, we propose for the existence of synchronous pregnancies, which may be analogous to menstrual synchrony. Menstrual synchrony is a well studied topic, whereas synchronous pregnancies among friends or family members is an overlooked area of investigation. In this exploratory study of 81 pregnant women, we hypothesize that women's pregnancies are…

The goal is to provide a review of the ways in which both types of behavior enhance a mother’s reproductive success, and ultimately, show that the most beneficial strategy is integrate both cooperative and competitive behavior.



Menstrual synchrony under optimal conditions: Bedouin families.

Menstrual data were collected prospectively for 3 months from 27 Bedouin nuclear families living under conditions optimally conducive for synchrony: a highly sexually segregated society, standard living conditions, and minimal use of oral contraceptives.

Can Men Detect Ovulation?

In contrast to our closest cousin, the chimpanzee, humans appear at first to lack cues of impending ovulation that would mark the fertile period in which a female can become pregnant. Consequently,
