Read the given statements that define functions of a particular hormone.
(i) Regulates the development, maturation and functions of epiddymis, vas deferens, seminal vesicle, prostrate gland, urethra, etc.
(ii) Stimulates muscular growth of facial and axillary hair, aggressiveness, low pitch of voice, etc.
(iii) Stimulates spermatogenesis.
(iv) Act on CNS and sexual behaviour (Libido).
(v) Produce anabolic (synthetic) effect on protein and carbohydrate metablosim.
(vi) The Leydig,s cells/intestitial cells (present in interbular space). Secrete this hormone under the influence of LH.
Which of the following hormones is referred here?

Options

A. FSH
B. Progestrone
C. Androgen
D. Melatonin

Answer

To determine which hormone is being described in the statements provided, we can analyze each statement step by step:

1. **Statement Analysis**:
- **Statement (i)**: "Regulates the development, maturation and functions of epididymis, vas deferens, seminal vesicle, prostate gland, urethra, etc."
- These are all male reproductive organs, indicating that the hormone in question is likely a male hormone.

2. **Statement (ii)**: "Stimulates muscular growth of facial and axillary hair, aggressiveness, low pitch of voice, etc."
- These characteristics are typically associated with male secondary sexual characteristics, further suggesting that the hormone is related to male physiology.

3. **Statement (iii)**: "Stimulates spermatogenesis."
- Spermatogenesis is the process of sperm formation, which is a function of male reproductive hormones.

4. **Statement (iv)**: "Act on CNS and sexual behaviour (Libido)."
- This indicates that the hormone has effects on the central nervous system and influences sexual behavior, which is again consistent with male hormones.

5. **Statement (v)**: "Produce anabolic (synthetic) effect on protein and carbohydrate metabolism."
- Anabolic effects are often associated with hormones that promote muscle growth and overall physical development, which aligns with male hormones.

6. **Statement (vi)**: "The Leydig's cells/interstitial cells (present in intertubular space) secrete this hormone under the influence of LH."
- Leydig cells are known to produce testosterone, which is a type of androgen, in response to luteinizing hormone (LH).

Based on the analysis of all six statements, the hormone being referred to is **androgen**.

### Final Answer:
The hormone referred to in the statements is **androgen**.
