Contraceptive Failure Rate List
1. Calculating ovulation period
Failure rate: 2-20%
Calculating women’s ovulation period is a natural contraceptive method without using any contraceptive measures. The advantage is that it will not create any impression and side effects on the body, but the failure rate is very high. First, because women’s ovulation period will often be different, it is difficult to accurately calculate the ovulation period. Second, it is necessary for couples to cooperate fully and establish regular sexual life.
2. Condoms
Failure rate: 2-15%
Most people choose condoms as a method of contraception, but they are eager to purchase and use them easily.
