TI  - Gonadotropin antagonist modulates courtship behavior in male red-sided garter 
      snakes, Thamnophis sirtalis parietalis.
PG  - 137-43
AB  - Behavioral studies were used to investigate the central effects of chicken-I 
      GnRH, chicken-II GnRH, and D-Phe2,6,Pro3-GnRH, a GnRH antagonist, on the 
      courtship behavior of male red-sided garter snakes, Thamnophis sirtalis 
      parietalis. Intracerebroventricular (i.c.v.) injections of chicken-I or 
      chicken-II GnRH had no effect on time spent courting or latency to court when 
      experimental males were exposed to unmated females, or when experimental males 
      were exposed to the female sex attractiveness pheromone. I.c.v. injections of 
      D-Phe2,6,Pro3-GnRH caused a significant decrease in latency to court when 
      experimental males were exposed to unmated females. When males injected with 
      D-Phe2,6,Pro3-GnRH were exposed to the female sex attractiveness pheromone, it 
      caused a significant increase in time spent courting compared to that in 
      saline-injected controls. D-Phe2,6,Pro3-GnRH was not able to initiate courtship 
      behavior during the nonbreeding season, indicating that courtship behavior is 
      dependent on the interaction of multiple components. This study does demonstrate 
      that a hormone or neuropeptide can modulate sexual behavior in garter snakes.
