A female undergo hysterectomy, which one of the following event will not occur ?

Options

A. Formation of Graafian follicle
B. Ovulation
C. Menstruation
D. Completion of meiosis - I and formation of secondary oocyte

Answer

**Step-by-Step Solution:**

1. **Understanding Hysterectomy**: Hysterectomy is a surgical procedure that involves the removal of the uterus. This procedure can affect various physiological processes in a female's reproductive system.

2. **Identifying the Functions of the Uterus**: The uterus plays a crucial role in the menstrual cycle and pregnancy. It is the site where a fertilized egg (zygote) implants and develops into a fetus. Additionally, the uterus is involved in the menstrual flow, which occurs when there is no fertilization.

3. **Effects of Hysterectomy on Menstruation**: After a hysterectomy, the uterus is no longer present, which means that the menstrual flow will cease. Menstruation is directly linked to the presence of the uterus, as it involves the shedding of the uterine lining.

4. **Ovarian Function Post-Hysterectomy**: The ovaries continue to function normally after a hysterectomy. They will still produce eggs (ova) and release them during ovulation. The hormonal regulation by the pituitary gland remains intact, so processes like the formation of Graafian follicles and ovulation will continue.

5. **Completion of Meiosis**: The completion of meiosis and the formation of secondary oocytes occur in the ovaries, which are not removed during a hysterectomy. Therefore, these processes will not be affected by the removal of the uterus.

6. **Conclusion**: Given the options provided (formation of Graafian follicles, ovulation, menstruation, completion of meiosis 1, and formation of secondary oocytes), the event that will not occur after a hysterectomy is **menstruation**.

**Final Answer**: The event that will not occur is **menstruation**.
