In addition to men's use of condoms, contraceptive methods based on calculating the safe period and external ejaculation are widely discussed. However, the former is difficult to accurately predict "safe days" because women's ovulation period is easily affected by emotions or other physical conditions, while the latter is due to Before men ejaculate, or a small amount of secretion will be discharged together with sperm, which may lead to pregnancy, so neither is a good method of contraception.<\/p>\n
There are currently two types of contraceptive pills. One is a mixed hormonal contraceptive that contains estrogen and progesterone, which can inhibit ovarian ovulation and thicken cervical mucus to prevent sperm from approaching; the other only contains The progesterone component is mainly provided to women who are not suitable for using estrogen. Some people may experience symptoms such as nausea, vomiting, headache, breast tenderness, slight weight gain, and slight dizziness at the beginning of taking the medicine, which usually disappear after a few weeks.<\/p>\n
Birth control injections are a more convenient option. Women only need to inject the first dose of contraceptive injection within the first 5 days of menstrual cramps, and then inject regularly. The hormone components in the injection can inhibit ovulation and achieve contraception. Basically, as long as you receive injections on time, the success rate of contraception can be as high as 99.7%. However, it should be noted that more than 60% of women will experience menstrual disorders during the injection period; .<\/p>\n
An IUD is ideal for couples who need long-term contraception. After the doctor evaluates the case, he will choose the suitable intrauterine ring according to the individual situation. The placement process is simple, no anesthesia and pain relief are required, the success rate of contraception is as high as 98% to 99%, and it does not affect sexual life. However, women may have slight vaginal bleeding and more secretion for a few days after wearing it, and the first few menstrual periods will also have more flow and mild menstrual pain. These phenomena will gradually dissipate afterward.<\/p>\n
When it comes to permanent birth control, it's female sterilization. The principle is to cut off the bilateral fallopian tubes through surgical operation to achieve the purpose of permanent contraception, and the effect is almost 100%. Unless there is another operation to connect the fallopian tubes, the chance of pregnancy is very small, so if there is any doubt, it is not advisable to undergo surgery, so as to avoid unnecessary troubles in the future.<\/p>\n
