Progesterone pill helps in preventing pregnancy by not allowing

Options

A. Ova formation
B. Fertilization
C. Implantation
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding Progesterone Pills**: Progesterone pills, such as Saheli, are a form of hormonal contraception used to prevent pregnancy.

2. **Mechanism of Action**: These pills work primarily by affecting the reproductive system in several ways:
- **Thickening of Cervical Mucus**: The pills increase the thickness of the cervical mucus, which creates a barrier that sperm cannot easily penetrate. This prevents sperm from reaching the uterus.

3. **Inhibition of Ovulation**: Progesterone pills also inhibit ovulation, which is the release of an egg (ovum) from the ovary. If ovulation does not occur, there is no egg available for fertilization.

4. **Prevention of Fertilization**: Since there is no ovum released, fertilization cannot take place as there is no egg for the sperm to fertilize.

5. **Prevention of Implantation**: If fertilization were to occur, the pills would also prevent implantation of a fertilized egg into the uterine lining. However, since ovulation is inhibited, this step is not necessary for preventing pregnancy.

6. **Conclusion**: Therefore, the correct answer to the question is that progesterone pills help in preventing pregnancy by not allowing ovum formation (ovulation).

**Final Answer**: Progesterone pills help in preventing pregnancy by not allowing ovum formation.
