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

Options

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

Answer

To answer the question about which structure produces several hormones like hCG, hPL, estrogen, and progesterone, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the hormones mentioned**: The hormones in question are hCG (human chorionic gonadotropin), hPL (human placental lactogen), estrogen, and progesterone.

2. **Understand the function of each hormone**:
- **hCG**: This hormone is crucial for maintaining the corpus luteum during early pregnancy, which in turn supports the production of progesterone.
- **hPL**: This hormone plays a role in regulating maternal metabolism and promoting fetal growth.
- **Estrogen**: This hormone is involved in the development of female secondary sexual characteristics and plays a vital role in the menstrual cycle and pregnancy.
- **Progesterone**: This hormone is essential for maintaining the uterine lining for a potential pregnancy.

3. **Determine the source of these hormones**:
- **Ovary**: Produces estrogen and progesterone but not hCG or hPL.
- **Placenta**: Produces hCG, hPL, estrogen, and progesterone during pregnancy.
- **Fallopian Tube**: Does not produce these hormones.
- **Pituitary Gland**: Produces other hormones but not these specific ones.

4. **Conclude the correct answer**: Since the placenta is responsible for the production of all four hormones mentioned, the correct answer is the placenta.

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