Endocrine

Protein and steroid hormones.

  • Human chorionic gonadotrophin (hCG) - like leutenizing hormone, supports corpus luteum in ovary, pregnant state rather than menstrual, maternal urine in some pregnancy testing
  • Human chorionic somatommotropin (hCS) - or placental lactogen stimulate (maternal) mammary development
    • rise through pregnancy, stimulates maternal metabolic processes, breast growth
  • Human chorionic thyrotropin (hCT)
  • Human chorionic corticotropin (hCACTH)
