Which of the following hormones is not secreted by human placenta?
Show Hint
During pregnancy, high levels of placental hormones actually suppress LH and FSH from the pituitary to prevent further ovulation.
Updated On: Apr 26, 2026
- Progestogen
- hCG
- Estrogen
- LH
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
The placenta acts as a temporary endocrine gland during pregnancy. it secretes several hormones essential for maintaining the pregnancy and supporting fetal development.
Step 2: Detailed Explanation:
1. hCG (Human Chorionic Gonadotropin): Produced early by the placenta; it's what pregnancy tests detect. 2. hPL (Human Placental Lactogen): Produced by the placenta to regulate metabolism. 3. Estrogens and Progestogens: The placenta takes over the production of these from the corpus luteum to maintain the uterine lining. 4. LH (Luteinizing Hormone): This hormone is secreted by the Anterior Pituitary Gland, not the placenta. Its primary role is to trigger ovulation in a non-pregnant cycle.
Step 3: Final Answer
LH is the hormone not secreted by the human placenta.
