Which hormone helps in detection of pregnancy?

Options

A. hCG
B. hPL
C. Prolactin
D. Progesterone

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which hormone is responsible for the detection of pregnancy. This implies we need to identify a hormone that is specifically associated with confirming pregnancy.

2. **Identifying the Hormones**: The options provided are:
- Option 1: HCG (Human Chorionic Gonadotropin)
- Option 2: HPL (Human Placental Lactogen)
- Option 3: Prolactin
- Option 4: Progesterone

3. **Analyzing Each Hormone**:
- **HCG**: This hormone is produced by the placenta shortly after a fertilized egg attaches to the uterine lining. It is the hormone that pregnancy tests detect to confirm pregnancy.
- **HPL**: This hormone is involved in metabolic regulation during pregnancy but is not used for pregnancy detection.
- **Prolactin**: This hormone is primarily responsible for milk production and is released from the anterior pituitary gland, not directly related to pregnancy detection.
- **Progesterone**: This hormone is crucial for maintaining pregnancy but is not the hormone used for detecting pregnancy.

4. **Conclusion**: Based on the analysis, the hormone that helps in the detection of pregnancy is HCG (Human Chorionic Gonadotropin). It is specifically produced by the placenta and is the hormone detected in pregnancy tests.

5. **Final Answer**: The correct answer is HCG.
