SYNERGISM OF ESTROGENS WITH PITUITARY GONADOTROPINS IN HYPOPHYSECTOMIZED RATS1

Abstract
The synergic action of stilbestrol with chorionic gonadotrophin in bringing about development of the ovaries of hypophysectomized rats was confirmed. Two hypophyseal gonadotrophic fractions (FSH and ICSH) were tested for this synergic action with stilbestrol and the synergism was shown to exist in the case of stilbestrol and FSH.
