Identify the hormone that stimulates the formation of corpus luteum.

Options

A. Thyroid stimulating hormone
B. Follicle stimulating hormone
C. Luteinizing hormone
D. Prolactin hormone

Explanation

**Step-by-Step Solution:**

1. **Understanding Corpus Luteum**: The corpus luteum is a temporary endocrine structure in the ovaries that plays a crucial role in the menstrual cycle and early pregnancy. It forms after ovulation from the remnants of the follicle.

2. **Role of Hormones in Corpus Luteum Formation**: The formation of the corpus luteum is primarily stimulated by certain hormones released during the menstrual cycle.

3. **Identifying the Relevant Hormones**:
- **Thyroid Stimulating Hormone (TSH)**: This hormone is secreted by the pituitary gland and primarily stimulates the thyroid gland to produce thyroid hormones. It does not play a role in the formation of the corpus luteum.
- **Follicle Stimulating Hormone (FSH)**: This hormone is involved in the regulation of the menstrual cycle and the growth of ovarian follicles but does not stimulate the formation of the corpus luteum.
- **Luteinizing Hormone (LH)**: This hormone is crucial for the ovulation process and is responsible for triggering the formation of the corpus luteum after ovulation occurs.
- **Prolactin**: This hormone is primarily involved in milk production and the development of mammary glands, not in the formation of the corpus luteum.

4. **Conclusion**: Among the hormones discussed, luteinizing hormone (LH) is the one that stimulates the formation of the corpus luteum.

5. **Final Answer**: The hormone that stimulates the formation of the corpus luteum is **Luteinizing Hormone (LH)**.
