Which one is a gonadotrophic hormone ?

Options

A. Collip's hormone
B. Prolactin
C. Oxytocin
D. Luteinizing hormone.

Answer

**Step-by-Step Solution:**

1. **Identify the Options**: The question asks for a gonadotrophic hormone among the given options: colipsal hormone, prolactin, oxytocin, and luteinizing hormone.

2. **Understand Gonadotrophic Hormones**: Gonadotrophic hormones are those that stimulate the activity of the gonads (testes in males and ovaries in females). The primary gonadotrophic hormones are Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH).

3. **Analyze Each Option**:
- **Colipsal Hormone**: Not recognized as a gonadotrophic hormone.
- **Prolactin**: Primarily involved in milk production and not classified as a gonadotrophic hormone.
- **Oxytocin**: Involved in childbirth and lactation, but not a gonadotrophic hormone.
- **Luteinizing Hormone (LH)**: Known to stimulate gonadal activity, making it a gonadotrophic hormone.

4. **Conclusion**: Among the options provided, Luteinizing Hormone (LH) is the correct answer as it is a gonadotrophic hormone.

5. **Additional Information**: LH is released by the anterior pituitary gland and plays a crucial role in both male and female reproductive systems. In males, it stimulates testosterone production, while in females, it triggers ovulation and supports the corpus luteum.

**Final Answer**: Luteinizing Hormone (LH) is a gonadotrophic hormone.
