Lutenising hormone is

Options

A. Lactotropic
B. Mammotropic
C. Non-mammotropic
D. Both A and B

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the classification of luteinizing hormone (LH) among the given options: Lactotropic, Mammotropic, Non-Mammotropic, or both A and B.

2. **Defining Lactotropic and Mammotropic Hormones**:
- **Lactotropic Hormones**: These hormones are primarily involved in lactation, which is the process of milk production. The main lactotropic hormone is prolactin, which promotes milk synthesis.
- **Mammotropic Hormones**: These hormones also relate to mammary gland function, including the development of mammary glands and the ejection of milk. Oxytocin is an example of a mammotropic hormone.

3. **Identifying the Functions of Luteinizing Hormone**:
- Luteinizing hormone is secreted by the pituitary gland and plays a crucial role in the reproductive system.
- Its primary functions include stimulating ovulation (the release of an ovum from the ovary), promoting the formation of the corpus luteum (a structure that develops from the follicle after ovulation), and inducing the secretion of progesterone from the corpus luteum.

4. **Analyzing the Options**:
- Since luteinizing hormone does not have any functions related to lactation or mammary gland development, it does not fit the definitions of lactotropic or mammotropic hormones.
- Therefore, it is classified as a **Non-Mammotropic** hormone.

5. **Conclusion**: The correct answer is that luteinizing hormone is a **Non-Mammotropic** hormone (Option C).
