title: Biological and immunological studies of a placental gonadotropic protein.
abstract: Precocious sexual maturity, ovarian weight increase and stimulation of the sex accessory organs in impuber female mice, was induced by a partially purified protein fraction obtained from human placenta. The relationship between this biologically active protein and HCG was studied by a comparative immuno-double diffusion technique (Ouchterlony) and two agglutination inhibition tests. Results showed that this protein with gonadotropic activity is neither immunologically related to HCG nor contaminated with this hormone.
