Which of the following is natural method of contraception ?

Options

A. Sterilization
B. IUD
C. Diaphragm
D. Periodic abstinence

Answer

To determine which of the following is a natural method of contraception, we will analyze each option provided:

1. **Sterilization**:
- Sterilization is a surgical procedure aimed at making an individual incapable of reproduction. This method is not natural as it involves surgical intervention. Therefore, this option is incorrect.

2. **IUD (Intrauterine Device)**:
- An IUD is a small device inserted into the uterus to prevent pregnancy. It is a medical device and involves a procedure to place it inside the body. Since it is not a natural method, this option is also incorrect.

3. **Diaphragm**:
- The diaphragm is a barrier method of contraception that is placed inside the vagina to block sperm from entering the uterus. It is used in conjunction with spermicide. As it is a mechanical barrier and not a natural method, this option is incorrect as well.

4. **Periodic Abstinence**:
- Periodic abstinence refers to the practice of refraining from sexual intercourse during the fertile period of a woman’s menstrual cycle. This method relies on the natural understanding of the ovulation cycle and does not involve any medical procedures or devices. Therefore, this is considered a natural method of contraception.

**Conclusion**: The correct answer is **Periodic Abstinence**.
