摘要: Publisher Summary This chapter discusses the production and activity of placental releasing hormones. The human placenta produces a number steroid protein Some these have been chemically defined—for example, progesterone, chorionic somatomammotropin (hCS), gonadotropin (hCG). There is also evidence for presence other pituitary hormone–like activities in placenta, such as thyrotropin, adrenocorticotropic, melanocyte-stimulating hormone. factors involved control hormones are not known. However, few agents shown to be effective stimulating or inhibiting release contains hormones, gonadotropin-releasing hormone, thyrotropin-releasing somatotropin-releasing factor. In addition gonadotropin–releasing hormone (hCGnRH) has detected placenta. describes findings related chemical nature hCGnRH its possible action during pregnancy. hCGnRh present primarily cytotrophoblast total content concentration vary with gestational age.
