Document Summary
The exact timing of female ovulation is unknown to both the male and female species. Marked by increases in female sexual behavior (proceptivity) and attractiveness at the period of highest fertility just before ovulation. Period of pronounced genital swelling/ in heat . Readiness to copulate when solicited by a male. No difference in receptivity between humans and primates. The younger males with higher levels of testosterone constantly solicit females (even without signs of estrus) Similar to humans in that there is more of a constant receptivity. Active encouragement and solicitations by females to copulate. This behavior is more limited in primates to times during estrus. Proceptive actions peak during periovulatory period of maximum swelling. During estrus males find females sexually attractive, thus initiating copulations. Most of the female primate menstrual cycle is characterized by sexual disinterest from males until estrus. Show 94-96% increase in mating during estrus. Genital swellings are visual in nature and attract males.
