normal
Which of the following groups of hormones are produced in women only during pregnancy?
A
$hCG, hPL$, relaxin
B
Estrogen, progesterone, $hCG$
C
Cortisol, prolactin, thyroxine
D
Prolactin, progesterone, $hCG$
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.
