Which of the following contraceptive method make the uterus unsuitable for implantation?

Options

A. Condom
B. Mala-D
C. Diaphragms
D. IUD

Answer

To determine which contraceptive method makes the uterus unsuitable for implantation, we can analyze each option provided:

1. **Condom**:
- Condoms are barrier methods used by males to prevent sperm from entering the female reproductive tract.
- They do not alter the uterine environment, so implantation can still occur if sperm is present.
- **Conclusion**: Condoms do not make the uterus unsuitable for implantation.

2. **Malady (Contraceptive Pills)**:
- Contraceptive pills contain synthetic hormones that regulate the menstrual cycle and prevent ovulation.
- While they alter hormone levels, they do not directly change the uterine environment to prevent implantation.
- **Conclusion**: Contraceptive pills do not make the uterus unsuitable for implantation.

3. **Diaphragms**:
- Diaphragms are also barrier methods that prevent sperm from reaching the egg.
- Similar to condoms, they do not affect the uterine environment, allowing for the possibility of implantation.
- **Conclusion**: Diaphragms do not make the uterus unsuitable for implantation.

4. **IUD (Intrauterine Device)**:
- IUDs are devices placed inside the uterus that change the intrauterine environment.
- They create a spermicidal environment, increasing phagocytosis of sperm and preventing implantation.
- **Conclusion**: IUDs make the uterus unsuitable for implantation.

Based on the analysis, the correct answer is **IUD**.
