[Decrease in the secretion of anti-Müllerian hormone by the chick testis during development].
At the end of embryonic life the chick embryonic testis possesses a low anti-Müllerian activity, as evidenced by the grafting method to female hosts. The percentage of grafted embryos presenting a Müllerian duct regression is not increased by administration of an anti-estrogenic drug (tamoxifen). This observation does not favour the hypothesis according to which the low percentage of regression could be due to a protection of Müllerian ducts by estrogens from the host ovary. It shows rather that the anti-Müllerian hormone secretion actually decreases during development.
