abstract：:Activation of mu-opioid receptors is critical to steroid regulation of female sexual behavior, lordosis, in rodents. Estrogen treatment activates mu-opioid receptors in the medial preoptic area inhibiting lordosis, but ultimately appears important for progesterone facilitation of lordosis. We investigated the role of ...
