The Placenta is a Source of All of the Following

Question

The placenta is a source of all of the following hormones, except
A) hCG.
B) relaxin.
C) placental lactogen.
D) progesterone.
E) luteinizing hormone.

Accepted Answer

The placenta does not secrete luteinizing hormone (LH), which is produced by the anterior pituitary gland in the brain. LH plays a role in stimulating ovulation during the menstrual cycle. The other hormones listed (hCG, relaxin, placental lactogen, and progesterone) are all secreted by the placenta.
