Solution

$hPL$ (= 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.
