| Abstract: | Crystalline prostaglandin E2 (PGE2) induced high levels of sexual receptivity when stereotaxically implanted into the anterior-basal hypothalamic and preoptic regions of estrogen-primed, ovariectomized rats. Anterior- as well as medial basal hypothalamic implants of PGE2 induced a significant elevation of rectal body temperature, but had no effect on open-field activity scores. The possibility that PGE2 exerts its facilitatory effects upon sexual receptivity via an LHRH mechanism is discussed. |
