Options

B. Estrogen, progesterone, hCG
C. Cortisol, prolactin, thyroxine
D. Prolactin, progesterone, hCG

Answer

A

Explanation

hPL (= human placental lactogen) has lactogenic properties, thus supporting prolactin from mother's pituitary during pregnancy. hCG (= human chorionic gonadotrophin) stimulates corpus luteum of pregnancy to continue secrete progesterone. Relaxin, secreted by corpus luteum, facilitates parturition by softening the connective tissue of public symphysis.
