In addition to keeping yourself away from possible diseases, safe sex is also a plan for future life. To avoid unintended pregnancy disrupting the rhythm of life, sexual health managers share eight contraceptive methods to protect their reproductive health. Women generally have a childbearing period of about 30 years. Unexpected pregnancy not only causes distress for young girls, but also changes the lives of families and individuals in the future. The choice of abortion has great sequelae for female reproductive health. Therefore, “contraception” is not only a multiple-choice question related to the succession of the ancestors, but also an important decision for women to protect their own reproductive health and to take ownership of their own lives. Generally, to achieve the purpose of pregnancy, the following three steps must be taken: (1) normal ovulation (2) fertilization of spermatozoa (3) implantation in the uterus, and the method of contraception is to interfere with one of the above steps to complete. There are many methods of “contraception”. The application varies from person to person and is closely related to the physical function of each person. Let the sexual health manager arrange the way to prevent pregnancy. Vasectomy and tubal ligation (successful contraception 99. 999%): Does not affect the endocrine and nervous system, nor does it affect sexual desire and sexual function. Condoms (99% of successful contraception): At the same time, it achieves the purpose of contraception and prevention of sexually transmitted diseases. There are no side effects of any damage mechanism. It is divided into male (penis) and female (vaginal). Otherwise, there may still be a risk of conception or sexually transmitted diseases. Oral contraceptives (more than 90% of successful contraception): Contraceptive effect is good, but as soon as you stop taking it, you will resume fertility. So once you start taking oral contraceptives, use your mobile phone or electronic alarm reminder to remind yourself to take it at a fixed time. The downside is that it can cause side effects. After-the-fact contraceptives (successful contraception 75%): The first dose is taken within 72 hours after the house, and the second dose is taken after about 12 hours. It should be noted that taking a contraceptive pill can only provide protection for the next sexual act. If there is sexual activity afterwards, the contraceptive effect is unreliable. Vaginal septum – uterine cap (98% of successful contraception): has no effect on women’s hormone metabolism, easy to use does not interfere with sexual intercourse, and may also reduce the incidence of cervical cancer. The disadvantage is that it may be allergic to latex material, or cause bladder infection and urethritis. Intrauterine device (50% for successful contraception): It is best to install the intrauterine device for the week after the menstruation. Usually, the cervix is opened at this time, and the possibility of pregnancy can be more clearly ruled out. If you are pregnant, you should take out the contraceptive immediately. Calculate the safety period and the dangerous period (the lowest rate of contraceptive success): the most unreliable method of contraception! From the beginning of follicular formation, ovulation after maturity, the egg begins to degeneration without fertilization within 24 to 36 hours, degeneration to form menstruation, this time to pay attention to contraception is about 10 days, commonly known as the dangerous period. Because the survival time of sperm is about 24 to 72 hours, the chance of conception is highest on the 4th to 7th day of the dangerous period. So how can women know that they are in a dangerous period? (1) If the menstrual cycle is very stable, you can use the calendar to record well. If you know the next time, you can calculate the dangerous period. note! As long as it is not an absolutely stable menstrual cycle, and even has many experiences of ovulation or ovulation, this method is completely ineffective. (2) The basal body temperature is the lowest temperature of the body in the state of complete relaxation, so it should generally be performed immediately after waking up to avoid any body movement before. It is recommended to continue measuring for one month, and then start to calculate, the days when the body temperature is high is the ovulation period. note! Climate change and physical and emotional fluctuations may affect body temperature, and there are still saliva measurements on the market. Thermometers, you must ask for accurate numbers. (3) Observing changes in vaginal secretions. Generally speaking, the increase of leucorrhea due to estrogen increase during follicular development, and gradually decrease after estrogen decline after ovulation, but endocrine changes are susceptible to various factors, so the calculation period is safe. Contraceptive success rate is the lowest, and no rules can be applied to everyone. 8. Spermicide: used to kill sperm, in order to ensure the effect, should be placed in the vagina for 4-5 hours, should not be washed away immediately after sexual intercourse. The above eight methods of contraception are for readers’ reference, but there are some wrong contraceptive methods that should never be tried, such as in vitro ejaculation (or sexual intercourse interruption), safety period (7 before and after menstruation), cleaning the vagina after sex, etc. The network has no scientific evidence. Sex education should begin before sexual activity has been carried out, in addition to teaching women to maintain sexual autonomy in the face of voluntary or involuntary sexual behavior. Men should not refuse to use condoms on the grounds that they are not comfortable enough or reduce their sexual pleasure. Women should also insist on using condoms. It is also necessary to rule out the concept of shame behavior when buying condoms. It is also necessary to learn to use condoms correctly and make condoms truly An important guardian of sexual health and prevention of unwanted pregnancies.
