✦ Synopsis
Adult female green iguanas (Iguana iguana) were treated with repetitive pulses of chicken gonadotropin (d-Arg' chicken 10 releasing hormone (GnRH) delivered by interperitoneal osmotic pumps. Total estrogen levels in serum decreased from 37.3 f 18.0 pg/ml to 5.4 + 4.6 pg/ml 9 days after the pump was implanted. Estrogen levels returned to pre-implant levels 5 days after the end of the treatment period. The behavior of male iguanas, housed with the treated females, was influenced while the pumps were functioning. The frequency of assertive displays between males increased threefold after 7 days of GnRH treatment. Males actively interposed themselves between "their" female and other males during the same period.
