What is the principle of contraceptive thread embedding

In order to achieve better contraception, some female friends will choose the thread embedding method of contraception. This method is not rational at all and may lead to contraception failure. It is better to choose a better contraceptive method. The best is condom contraception, which is just to make contraception more successful. Basically, the success rate is above 95%, and contraceptive failure will not easily occur.

1. Safe period contraception method

Safe period contraception is a contraceptive method that stops sexual intercourse during the ovulation period. The key to using safe period contraception is to determine the woman's ovulation date. A woman's ovulation date is generally about 14 days before the next menstrual period. It is easy to get pregnant through sexual intercourse in the five days before and four days after ovulation, so it is also called the danger period.

For people with regular menstruation, it is relatively simple to determine the ovulation period. You can calculate the ovulation period based on the menstrual cycle, which is the 14th day before the next menstrual period. However, menstruation will change with the health of the body, environmental changes, and mood swings. The ovulation period calculated according to the menstrual cycle is not accurate enough, so the contraceptive failure rate is very high. Usually this method is only suitable for people with normal menstrual cycles, couples living together for a long time and who can correctly calculate the safe period. It is not recommended as the first choice method of contraception.

2. Condom contraception

Condoms, also known as safety condoms, are safe in two aspects. On the one hand, compared with the rhythmic period contraceptive method, their contraceptive success rate is high. If used correctly, their contraceptive rate can reach more than 95%. Compared with oral contraceptives and other methods, the use of condoms has almost no side effects. In addition to preventing pregnancy, it can also prevent sexually transmitted diseases such as trichomoniasis vaginitis, candidal vaginitis, bacterial vaginitis, genital herpes virus, genital warts, syphilis, and AIDS.

3. Oral contraceptives

The main ingredients of oral contraceptives are synthetic combined estrogen and progestin. According to the duration of contraceptive effect, it can be divided into three types: long-acting, short-acting and rapid-acting (for visiting relatives). The most commonly used one at present is the combined short-acting oral contraceptive.

Combined short-acting oral contraceptives are easy to take, have reliable contraceptive effects, are harmless to the human body, and do not affect future fertility. Generally, take the medicine after dinner before going to bed on the 5th day of menstruation, one tablet a day for 21 consecutive days, and stop taking the medicine for 7 days. Start the next cycle of contraception.

Contraceptive pills for visiting relatives are suitable for those who stay with relatives for more than 10 consecutive days. They can be taken after intercourse and are not restricted by the menstrual cycle. If you are visiting relatives for more than two weeks, you should take birth control pills instead.

For long-acting oral contraceptives, the first dose is 1 tablet after lunch on the 5th day of menstruation, and the second dose is taken 20 days later. Thereafter, the second dose day will be used as the monthly dose date, and one tablet will be taken each month.

4. Contraceptive injection

The progestin-only contraceptive injection is given once on the 5th day of menstruation and then once every 3 months thereafter. After using the pregnancy injection alone, about 2/3 of women experience irregular bleeding. Can be used in breastfeeding women.
