Abstrakt

Conventionally housed 130-160 g adult male Japanese quail were given gossypol acetic acid (gossypol) im at 25 mg/kg in 0.5 ml of 10% EtOH for 12 and 24 days (Groups 1 and 2), respectively. One day after treatment was terminated they were allowed to mate with laying females individually for 20 days. Fertility was 0% from mating of the Group 1 birds on days 1-2 and increased to 25, 35, 55 and 65% on days 3-6 after cessation of gossypol treatment. At day 11, fertility was 80 vs 84% in controls, whereas hatchability was 70% for both. By comparison, eggs from Group 2 mated quail were infertile for up to 20 days after the termination of gossypol treatment. In a parallel experiment, the percent testes to body weight ratio in control and 7, 14, 21, and 28-day gossypol-treated quail was 2.5, 2.2, 1.8, 0.5, and 0.2%, respectively. In 12 vs 24-day treated birds, 7, 14, 21, and 28 days after gossypol treatment, the ratios were 1.0 vs 0.5%, 2.0 vs 0.8% and 2.8 vs 1.9%, respectively. The decreased fertility and hatachability, and testicular atrophy resulting from gossypol given to male quail was dose-time related. Furthermore, the androgen-dependent cloacal gland was drastically reduced in size by the treatment with gossypol. The mode of action of gossypol in male quail is different than it is in mammals in that the testicular size of mammals remains unchanged with long-term gossypol treatment. It is concluded that quail may be a useful avian animal model for investigating the antifertility effects of gossypol.
