Mesntrual cycle is controlled by

Options

A. Estrogen and progesterone of ovary
B. FSH and LH of pituitary
C. Both A and B
D. FSH of pituitary.

Answer

**Step-by-Step Solution:**

1. **Understanding the Menstrual Cycle**: The menstrual cycle is a complex process that prepares the female body for potential pregnancy. It involves various hormones that regulate the cycle.

2. **Identifying Key Hormones**: The two main types of hormones involved in the menstrual cycle are:
- **Estrogen and Progesterone**: These are produced by the ovaries and play crucial roles in regulating the menstrual cycle.
- **FSH (Follicle-Stimulating Hormone) and LH (Luteinizing Hormone)**: These hormones are produced by the pituitary gland and are essential for the maturation of eggs and the regulation of the menstrual cycle.

3. **Role of FSH**: At the beginning of the menstrual cycle, FSH is released from the pituitary gland. It stimulates the ovaries to mature the follicles, which contain the eggs.

4. **Role of Estrogen**: As the follicles mature, they produce estrogen. This hormone is responsible for the thickening of the uterine lining and plays a role in the regulation of the menstrual cycle.

5. **Role of LH**: Following the increase in estrogen, there is a surge in LH, which triggers ovulation, the release of the egg from the follicle.

6. **Role of Progesterone**: After ovulation, the ruptured follicle transforms into the corpus luteum, which produces progesterone. This hormone helps maintain the uterine lining for a potential pregnancy.

7. **Conclusion**: Both the hormones from the ovaries (estrogen and progesterone) and the hormones from the pituitary gland (FSH and LH) are crucial for controlling the menstrual cycle.

8. **Final Answer**: Therefore, the menstrual cycle is controlled by both A (Estrogen and progesterone of ovary) and B (FSH and LH of pituitary), making the correct answer option C (Both A and B).
