The growth and maturation of Graafian follicle is caused by :

Options

A. FSH-LH
B. FSH-LTH
C. ACTH-LH
D. GH-ADH

Answer

To answer the question regarding the growth and maturation of the Graafian follicle, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Menstrual Cycle**:
- The menstrual cycle is divided into several phases, with the follicular phase occurring from day 1 to day 13.
- During this phase, follicles in the ovaries begin to develop.

2. **Role of Hormones**:
- The growth and maturation of the Graafian follicle are primarily influenced by hormones secreted by the anterior pituitary gland.
- The two key hormones involved in this process are Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH).

3. **Function of FSH**:
- FSH is crucial for the growth and maturation of ovarian follicles, including the Graafian follicle.
- It stimulates the follicles to grow and produce estrogen.

4. **Function of LH**:
- LH also plays a role in the menstrual cycle, particularly in triggering ovulation.
- However, its primary action occurs later in the cycle, specifically around day 14 when ovulation occurs.

5. **Conclusion**:
- Since the question specifically asks about the growth and maturation of the Graafian follicle, the correct answer is FSH.
- Therefore, the growth and maturation of the Graafian follicle is primarily caused by Follicle Stimulating Hormone (FSH).

### Final Answer:
The growth and maturation of the Graafian follicle is caused by Follicle Stimulating Hormone (FSH).
