Which of the following hormones is not secreted by human placenta?
Show Hint

Updated On: Mar 29, 2025
- Progestogen
- HCG
- Estrogen
- LH
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The hormone not secreted by human placenta is LH (Luteinizing Hormone).
(A) Progestogen - Incorrect: Placenta secretes progesterone to maintain pregnancy.
(B) HCG - Incorrect: Human Chorionic Gonadotropin is the key placental hormone detected in pregnancy tests.
(C) Estrogen - Incorrect: Placenta produces estrogens (estriol) during pregnancy.
(D) LH - Correct: LH is secreted by the anterior pituitary, not placenta.
The correct answer is (D) LH, as this gonadotropin is exclusively of pituitary origin.
