title: Effect of LHRH and its analogues on the progesterone secretion of human granulosa cells in vitro.
abstract: Progesterone secretion of cultured human granulosa cells treated with LHRH or its analogues was measured. Granulosa cells were also stimulated with LH, FSH, cAMP or forskolin. No differences could be observed in the progesterone basal secretion of cultures treated with or without LHRH or its analogues and after the various stimulations. It was concluded that the clinical experience that the sensitivity of ovaries for gonadotropins after LHRH desensitization is decreased could not be explained with the peripheral effects of LHRH on the granulosa cells. From the data obtained, the lack of LHRH receptors in the ovaries are suggested in humans.
