From pregnancy to contraception, from ancient and modern contraceptive methods to scientific contraceptive advice, as well as abortion on women’s health hazards and a series of issues to do a detailed introduction. First, the three top contraceptive methods Many people ask me, in the end, what contraceptive methods are the most safe and reliable, in fact, contraceptive methods are good and bad, respectively, is the failure rate of contraception, I summarized the following three kinds, they are the failure rate of less than 3 (100 women, one year, the failure rate of contraception with this method is less than 3 times) so that is already a very successful contraceptive methods. They are: 1, male and female ligation I hope more men will hear this program, male ligation can not be recovered this statement is widely circulated, may be due to the high social status of men for a long time, so the physical risks and contraceptive responsibility are transferred to women, in fact, male ligation is the safest of all the top contraceptive methods, the smallest side effects and can be recovered at a high rate! Female ligation is also one of the top contraceptive methods, the recovery rate is 80-90%, but the recovery rate is less than that of male, so male ligation is actually a better choice. Female ligation is done by cutting off half to one centimeter of the fallopian tube from the “braid” position where my finger is pinched, or by injecting some “plugging agent” from the vagina to block it, these different methods are called female sterilization. These methods are called female sterilization. 2, contraceptive ring As we mentioned in the last issue, the contraceptive ring is placed in the uterine cavity, the normally closed uterus will be wrapped around the contraceptive ring, and the position of the contraceptive ring is fixed in the uterine cavity. 3, the implant (skin buried) This is generally used for women, in the figure of a small syringe, thin white material, which contains some contraceptive pills, usually buried in the upper limbs, tube 3-5 years, the expiration date of the need to take out. Second, the second level of contraceptive methods There are also some of the failure rate in 3 to 9 (that is, 100 women, the failure rate of contraception with this method in a year is 3 to 9 times) method is also good. 1, oral contraceptives: every day to take, as long as it is standardized to take, the safety index of 99.99% or more! 2, hormonal vaginal built-in ring Hormonal drugs, placed in the vagina, once a month to take. 3, paste the skin on the contraceptive pill Like a plaster on the skin, a week to take off once, but this is not easy to buy. So relatively speaking, oral contraceptives, from easy to get and the effect is very good. Third, tertiary contraceptive method Tertiary contraceptive method includes contraceptive tools and safe period contraception, its failure rate of 10 to 20 (i.e., 100 women, the failure rate of contraception in a year with this method is 10 to 20 times). 1, instrumental contraception condom condom effective rate of more than 95%, the problem of contraceptive failure with condoms is mainly due to the lack of reasonable and effective use of it, there are the following precautions: a, buy good quality; b, condoms should be used throughout the whole process, rather than only in the ejaculation before wearing; c, choose the right size for yourself. The female contraceptive pad is placed inside the female vagina. The uterine cap is similar to a female condom and is placed at the top of the vagina before sex, which is very inconvenient and can also fall off and shift. Vaginal diaphragm placed throughout the vagina. 2, safe period contraception We often say that 7 days before menstruation or 8 days after menstruation is the safe period, in fact, this is considered very unreliable.
