Document Summary
Hormones not always enough to stimulation copulation. Influences from environment: social cues very important (affect engagability, arousal, etc; pei shortens is male put with a new female. 1) coolidge effect: enhanced mating in sated males if new female presented. In wild pacing is better because they can run around/ hide. Pacing helps the female in higher chances of getting pregnant. Males cant corner the female like in lab experiments. 3) stimulus value (attractivity) of females differ depends on age, hormonal status: males like females that are younger then themselves, with an older female, male will less likely engage in copulation. Once thought that it was due to differences in t. Castrated and retested: low t group stopped mating first. All given back same dose of t: behavior went back to original levels, not the same level. Animals do not differ because of differences in t differences reflect differences in target tissue sensitivity: ar/er content in mpoa.
