Fertile semen from 9-week-old chicks treated with tamoxifen.
White Leghorn male chicks were injected with 1 mg/kg BW of tamoxifen (an anti-estrogen) on alternating days between 2 and 9 wk of age. This treatment increased testes weight and induced semen production in response to the abdominal massage procedure. Insemination of laying hens with this semen resulted in hatching of live chicks from their eggs.
