title: [The content of gonadotropic hormones in commercial immunoglobulin preparations].
abstract: The authors carried out a comparative quantitative and biological determination of gonadotropins in 32 batches of immunoglobulin preparations made of the abortive, placental, and donor blood sera. The maximal amounts of gonadotropins were contained in preparations obtained from the abortive blood serum. It was shown that purification by Kohn's method (variant B) led only to the partial purification of immunoglobulins from the gonadotropin admixtures.
