At A Glance
The Reproduction Collaboratory has made significant discoveries about sexual behavior in five major areas: the medial amygdala, estrogens, energetics, steroid responsiveness and sex differences. Discoveries include:
- Phytoestrogen supplements, an increasingly popular
soy-derived alternative to estrogen replacement
therapy, do not produce the same molecular and
behavioral effects on the brain as endogenous estrogen
and can actually have anti-estrogenic effects on
female sexual behavior.
- Medroxyprogesterone acetate, a synthetic form
of the naturally occurring steroid hormone progesterone
widely used in contraceptives and hormone replacement
therapy, increases aggression and anxiety and reduces
sexual activity in female monkeys.
- Caenorhabditis elegans, a hermaphroditic
self-fertilizing nematode, produces a pheromone
that appears to regulate the male sex drive.
- Food restriction significantly suppresses both
reproductive and maternal behaviors in rodents.
- Visual sexual stimuli produce much higher levels
of activation in the amygdala of the male brain
than the female brain.
