[The effect of the testicular mullerian-inhibiting hormone on ovarian development in the chick embryo].

In female chick embryos grafted with embryonic testis, it is a correlation between the effects of the graft on the mullerian ducts and on the ovary. Indeed, when the graft causes retrogression of the ducts, it induces an ovarian atrophy also. These facts lead to think that these two activities are due to the same substance, the mullerian inhibiting hormone of the testis.
