In order to avoid the impact of condoms on men's pleasure and women's health, many people choose to use the method of calculating the safe period for contraception during sexual intercourse, believing that they can freely let go of sex during the safe period. There are at least 13 million induced abortions in China every year, and the number of failed cases of using safe period contraception is very small, so using the method of calculating safe period contraception is not safe.
The Best Date for Pregnancy
Women of normal childbearing age have one menstrual cycle per month. From this menstrual cycle to the first day of the next menstrual cycle, it is the menstrual cycle. The ovulation period is generally around 14 days before the onset of the second menstrual cycle. Therefore, in clinical practice, the first 5 days and the last 4 days connecting ovulation days are considered ovulation days, also known as the critical period. Generally speaking, the discharged eggs can survive for about 24 hours. After entering the female reproductive tract, sperm can maintain fertilization ability for 1-3 days. Therefore, from the first 3 days of female ovulation to the last 1 day of ovulation, the husband can conceive in the same room.
Safe period contraception
Safe period contraception refers to using contraception tools only during ovulation and not using contraception methods on other days. The failure rate of contraception during the safe period is very high, reaching 14.4% -47%. Long Yanqing said that the menstrual cycle of women remains unchanged, and many people's ovulation is not so correct, which is influenced by various factors and has undergone changes.
For example, due to excessive excitement, sometimes women may ovulate early or incorrectly. Women may ovulate twice during their menstrual cycle by taking drugs containing sex hormones, healthy foods, etc. Adolescent and work-related women often experience irregular menstruation, early or delayed menstruation, and lack a safe period. In theory, safe period contraception is only suitable for couples with very regular menstrual cycles, low life pressure, and long-term living together. In addition, they also need to be able to calculate correctly. However, there are too few such people.
Condoms are the most reliable
Even during the safe period, contraception is necessary. The use of condoms is the most ideal method of contraception, which is simple, easy to master, and does not require special guidance. The contraceptive effect is reliable. As long as condoms are used correctly and consistently, their success rate is higher than that of an intrauterine device.
The Durex condom is a barrier contraceptive device that allows men to engage in sexual intercourse on the penis. Semen can only flow inside the condom and cannot enter the female vagina, blocking the opportunity for sperm and eggs to meet, preventing fertilization and pregnancy, achieving contraceptive purposes.
