Use of estrogens or antiandrogens for reversal of male sexual phenotype in poultry

摘要

Fertilized poultry embryos are treated with estrogens or antiandrogens or estrogens in combination with antiandrogens during a period of embryonic development when the gonads are bipotential. This treatment causes genetic males to exhibit a female phenotype. When sex reversed male birds are crossed with normal male birds all offspring will be genotypically male.
