abstract
Progesterone is necessary in males for spermiogenesis and testosterone biosynthesis. The current study tested the hypothesis that progesterone is also a crucial modulator of sexual behavior in rams. Intact domestic white-faced rams (n = 8) and rams gonadectomized (GNX; n = 6) at 6 – 7 mo of age were exposed to ewes in estrus at 18 mo of age. Only intact rams exhibiting behavior toward estrous ewes and GNX rams showing an absence of reproductive behaviors were used to evaluate effects of progesterone. Expressed reproductive behaviors were categorized as investigatory (investigatory sniffs, flehmen, foreleg kicks, nudge, vocalization) or consummatory (mount attempts, mounts, ejaculations). Effect of progesterone was determined using a complete block randomized design with treatments separated by 14 d. GNX rams implanted with 4 doses of Synovex-h (testosterone + estradiol) were behavior tested following progesterone or vehicle treatment. Intact rams were behavior tested following treatment with the specific progesterone receptor antagonist, mifepristone (RU486) or vehicle. Behavior was monitored for 30 min twice during the vehicle and treatment period. note
