The placenta secretes numerous hormones both protein and steroid. Which of the following hormones is not secreted by the placenta?

Explanation:
Placental hormones include substances like hCG, estrogens (mostly estriol during pregnancy), and human placental lactogen, all secreted to support pregnancy and modulate maternal physiology. LH, on the other hand, is produced by the anterior pituitary gland and stimulates the ovaries to develop and ovulate an egg, as well as support the corpus luteum. After implantation, the placenta does not produce LH, though hCG from the placenta can mimic LH activity to help maintain early progesterone production by the corpus luteum. Therefore, LH is not secreted by the placenta.
