If both ovaris are removed from pregnant human femle in first trimester of pregnacy then it will lead to

Options

A. Abortion
B. Normal development
C. Irregular ovulation no fixed time interval
D. Menarche

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks what happens if both ovaries are removed from a pregnant human female during the first trimester of pregnancy.

2. **Identifying the Role of Ovaries**: The ovaries are responsible for producing hormones, particularly progesterone, which is crucial for maintaining pregnancy. During the first trimester, the corpus luteum (which forms from the ovulated follicle) is active in the ovaries and secretes progesterone.

3. **Impact of Ovarian Removal**: If both ovaries are removed, the production of progesterone will cease. This hormone is essential for maintaining the endometrial lining of the uterus, which supports the developing embryo.

4. **Consequences of Hormone Withdrawal**: Without progesterone, the endometrial lining cannot be maintained. This leads to the shedding of the lining, resulting in the termination of the pregnancy.

5. **Conclusion**: Therefore, if both ovaries are removed during the first trimester, it will lead to abortion, as the pregnancy cannot be sustained without the hormonal support provided by the ovaries.

### Final Answer:
The correct answer is **abortion**.
