The human placenta does not secrete which of the following hormone?

Options

A. Human chorionic gonadotropin (hCG)
B. Human placental lactogen (hPL)
C. Androgens
D. Progestogens

Answer

To solve the question "The human placenta does not secrete which of the following hormones?", we will analyze the options provided and determine which hormone is not secreted by the placenta.

### Step-by-Step Solution:

1. **Identify the Hormones**: We need to look at the hormones mentioned in the options. Common hormones associated with the placenta include:
- Human Chorionic Gonadotropin (HCG)
- Human Placental Lactogen (HPL)
- Progesterone
- Androgens

2. **Analyze HCG**:
- HCG is secreted by the placenta and is crucial for maintaining the corpus luteum during early pregnancy. It is often referred to as the "pregnancy hormone" because its presence can indicate pregnancy.

3. **Analyze HPL**:
- Human Placental Lactogen is also secreted by the placenta. It plays a role in fetal growth and helps regulate maternal metabolism during pregnancy.

4. **Analyze Progesterone**:
- Progesterone is a hormone that is vital for maintaining pregnancy. While it is produced by the corpus luteum initially, the placenta takes over its production as pregnancy progresses.

5. **Analyze Androgens**:
- Androgens are male hormones, and while they can be present in females, they are not secreted by the placenta. Instead, they are produced mainly by the adrenal glands and gonads.

6. **Conclusion**:
- Based on the analysis, the hormone that is not secreted by the human placenta is **Androgens**. Therefore, the correct answer is option 3.

### Final Answer:
The human placenta does not secrete **Androgens**.
