With the development of society, teenagers nowadays are increasingly exposed to sexual activity at an early age and do not understand anything, resulting in pregnancy. This summer vacation is coming to an end, and it is said that summer vacation is almost like maternity leave. Many hospitals can see the presence of middle school students. Mature women may still become pregnant without proper measures, so what is the probability of successful contraception during the safe period?
Probability of successful contraception during the safe period
According to the World Health Organization, in an ideal state, the annual failure rate of safe period contraception is about 5%, which is less reliable than condoms and oral short acting contraceptives.
However, in reality, achieving an ideal failure rate of 5% is also difficult. If simple calculation methods are used or if one's own physiological cycle is irregular, the failure rate will greatly increase. The clinical tracking annual failure rate can reach over 25%.
A 25% failure rate means that if 100 adult women use this method for contraception, 25 women will become pregnant within one year. The word 'safety' in the name has confused many people, but in fact, the risk is very high.
Precautions for contraception during the safe period
Due to the influence of emotions and diseases on women's menstrual cycle, the failure rate of contraception based solely on the calculation of the safe period is relatively high. Therefore, it is recommended to use it in combination with other contraceptive methods. The calculation of safe period contraception is not applicable to women with a period of less than 21 days, more than 35 days, or postpartum or breastfeeding. Before using safe period contraception, it is recommended that you record your cycle in the second half of the year to understand the regularity.
In addition to calculating the safe period, the ovulation date should also be determined by measuring basal body temperature and observing changes in vaginal discharge, in order to better determine the safe period of contraception.
The probability of successful contraception during the safe period has been introduced by the editor above. The probability of pregnancy during the safe period is very small, and having one's own measures will make it safer. Women should know when their cycle is. Ovulation period is usually around 14 days before the next menstrual period. To avoid pregnancy, sexual activity can avoid this time period.
