Abstract

The effect of progesterone (P4) on estradiol (E2)-induced sexual behaviors in ovariectomized French-Alpine goats, during both the breeding (fall) and the nonbreeding (spring) seasons, was examined. Progesterone facilitated E2-induced attractivity and receptivity in the nonbreeding season when P4 treatment occurred 48 or 72 hr prior to treatment with E2. During the breeding season, P4 facilitated attractivity when treatment occurred 72 hr prior to E2 injection. In contrast, P4 inhibited all sexual behaviors when treatment occurred 12 or 24 hr prior to injection of E2. Progesterone did not facilitate E2-induced proceptivity in either the breeding or the nonbreeding seasons. These findings demonstrate that both season and temporal sequence of P4 and E2 administration affect sexual behavior in ovariectomized French-Alpine goats.
