Which among the following hormoes is not secreted by adenohypophysis

Options

A. FSH
B. ICSH
C. LH
D. hCG

Answer

To determine which hormone is not secreted by the adenohypophysis (anterior pituitary gland), we can analyze the hormones listed in the options.

1. **Identify the Adenohypophysis**:
- The adenohypophysis is the anterior lobe of the pituitary gland. It is responsible for secreting several important hormones.

2. **List the Hormones Secreted by the Adenohypophysis**:
- The adenohypophysis secretes several hormones including:
- FSH (Follicle Stimulating Hormone)
- LH (Luteinizing Hormone)
- ICSH (Interstitial Cell Stimulating Hormone, which is essentially LH in males)
- ACTH (Adrenocorticotropic Hormone)
- TSH (Thyroid Stimulating Hormone)
- Prolactin
- GH (Growth Hormone)

3. **Analyze Each Option**:
- **Option 1: FSH** - This hormone is secreted by the adenohypophysis, so this option is incorrect.
- **Option 2: ICSH** - This is another name for LH in males, and it is also secreted by the adenohypophysis, so this option is incorrect.
- **Option 3: LH** - This hormone is secreted by the adenohypophysis, so this option is incorrect.
- **Option 4: HCG** - Human Chorionic Gonadotropin is not secreted by the adenohypophysis; it is secreted by the placenta during pregnancy. Therefore, this option is correct.

4. **Conclusion**:
- The hormone that is not secreted by the adenohypophysis is **HCG (Human Chorionic Gonadotropin)**.

### Final Answer:
The hormone that is not secreted by the adenohypophysis is **HCG (Human Chorionic Gonadotropin)**.
