Several hormones like hCG, hPL , estrogen, progesterone are produced by

Options

A. Ovary
B. Placenta
C. Fallopain tube
D. Pituitary

Answer

**Step-by-Step Solution:**

1. **Identify the Hormones**: The question mentions four hormones: hCG (human chorionic gonadotropin), hPL (human placental lactogen), estrogen, and progesterone.

2. **Understand the Source of Each Hormone**:
- **hCG**: This hormone is produced during pregnancy and is crucial for maintaining the corpus luteum, which in turn produces progesterone.
- **hPL**: This hormone is also produced during pregnancy and plays a role in regulating maternal metabolism and fetal growth.
- **Estrogen and Progesterone**: These hormones are primarily produced by the ovaries but are also secreted by the placenta during pregnancy.

3. **Recognize the Role of the Placenta**: The placenta is an organ that forms during pregnancy and serves as an interface between the mother and the fetus. It is responsible for the production of hCG and hPL, as well as contributing to the production of estrogen and progesterone.

4. **Eliminate Incorrect Options**:
- **Ovary**: While the ovary produces estrogen and progesterone, it does not produce hCG or hPL.
- **Fallopian Tube**: The fallopian tubes do not secrete any hormones.
- **Pituitary Gland**: The anterior pituitary secretes LH and FSH, which stimulate the ovaries but do not produce hCG or hPL.

5. **Conclusion**: The correct answer is that all four hormones (hCG, hPL, estrogen, and progesterone) are produced by the placenta during pregnancy.

**Final Answer**: The hormones hCG, hPL, estrogen, and progesterone are produced by the placenta.
