Now contraception has become a high concern, especially before unmarried must take preventive measures. The following friends to introduce the method of contraception

Methods/Steps
1

A, the most unsafe way of external ejaculation: success rate < 30% Which man can control the outbreak and migration of sperm? Almost nothing. A small amount of semen usually exits the urethral opening before ejaculation, and each drop contains about 50,000 sperm, which is enough to fertilize a woman's egg. In the sprint to the most intense stage, the time to pull out may be too late because of the man's attachment pleasure, and the ejaculation of semen you may not be able to feel. Safe period contraception: success rate < 30% Generally speaking, ovulation women, each menstrual cycle around ovulation there are 9 to 15 days is easy to conceive days, in addition to the days are relatively not easy to conceive, that is, people often say "safe period". Many women seem to trust the safe period as a pure "natural" method of contraception, but before that you must first understand your ovaries, that is, fully understand your ovulation cycle, know how to calculate the safe period, and make sure you have a lot of patience and no sex in the days outside the safe period, otherwise the "safe period" is just empty talk for you. Moreover, many factors can interfere with our bodies, such as emotional tension, environmental changes, stress, etc., and the failure rate of contraception during the safe period is particularly high. Recent studies in the West have found that sperm can survive up to eight days in the vagina. The survival time of eggs varies from 3 to 10 days depending on the individual. That is to say, in fact, there is a possibility of pregnancy from 8 days before ovulation to 10 days after ovulation, but the probability is low. Therefore, it is not possible to use contraception by calculating the safe period. The use of safe period contraception can not only be based on the day of the last menstrual cycle for reference, it is recommended that you record the menstrual cycle for half a year in order to understand the regularity of their menstruation. The vague concept of "one week before and after menstruation" cannot be trusted. The safe period method alone should not be used in the short term after the use of emergency contraceptives. When you decide to use the safe period of contraception, you must also insist that you do not have sex during the vulnerable pregnancy. Calculated safe period contraception is not suitable for women with a menstrual cycle of less than 21 days, more than 35 days, and postpartum or breastfeeding.

B, the most unhealthy way abstinence: success rate 100% success rate is high, but the loss of all the fun, is not necessarily beneficial to health. Menstrual contraception: Success rate < 30% Perhaps most people will not get pregnant during their period, but if you are that rare? And don't forget, sperm can live in the vagina for up to eight days. Another reason experts disapprove of menstruation is that it increases the incidence of endometriosis. In addition, the incidence of ectopic pregnancy is also related. In addition, menstruation may also make women lose more blood, which increases the likelihood of anemia. Moreover, if the sexual intercourse movement is too intense, it may also cause abdominal pain. Lactation: Success rate < 90% After birth, the baby's sucking action can reflexively inhibit the mother's hypothalamus, thus inhibiting ovarian ovulation. But this method is also not possible *, because if the baby sucking the nipple is reduced, the milk secretion is reduced, the milk concentration is reduced, or the mother is affected by the environment, climate, mood changes and sexual life, the inhibition of lactin on gonadotropin is weakened, the ovary will recover from the static state during breastfeeding and release mature eggs. Gradually resume the menstrual cycle. According to the survey, 5% to 10% of pregnant women are inexplicably conceived during lactation. "Whispers" reminds you that even during breastfeeding, you should pay attention to contraception, especially when there are the following unsafe factors: (1) breastfeeding less than 6 times a day; ② In half a year of lactation, the milk is thin and the milk volume is insufficient; ③ lactation period of more than half a year.

C, the most fashionable way of contraceptives: the contraceptive rate of 92% to 99.7% This is a preparation of contraception through skin absorption, the use of pharmaceutical control and release system to play the role of contraception. Its biggest advantage is that it is more convenient to use, and the concentration of drugs in the body is controlled at a relatively low and stable level, so as to avoid the side effects of too high concentration of drugs that many women worry about, such as weight gain, gastrointestinal reactions, and can achieve the purpose of long-term contraception. Menstrual modifiers and menstruation: contraceptive rate 99.7% Menstrual modifiers break the tradition that pregnancy is an absolute contraindication of contraceptives. When a woman's period expires a few days later, a take of this drug can induce menstruation, even if pregnant can also make the very early embryo natural abortion. The main components of seasonal menstruation are small doses of estrogen and progesterone. Just take the pink active pill for 84 days, and then take a placebo for menstrual purposes. In this way, in addition to contraception, women's menstruation can be changed to four times a year. This is undoubtedly a good news for women who suffer from dysmenorrhea and anemia due to excessive menstrual blood volume.

D, the most widely used way intrauterine device: success rate of 94% ~ 99% At present, more than 100 million women in the world use Iuds for contraception, 70% of women of reproductive age use Iuds. This is because the IUD is a long-acting contraceptive method, and the operation is simple, the contraceptive effect can reach 5 to 10 years after wearing, and the existence of foreign bodies will not be felt. In addition, Iuds do not disrupt and participate in the body's hormone production. However, if you have genital malformations or tumors, severe dysmenorrhea or excessive menstrual volume, pelvic inflammatory disease, gonorrhea and severe anemia, heart disease, and a history of ectopic pregnancy, it is not appropriate to wear Iuds. Pregnancy is also possible when the uterine ring is first placed. Therefore, other contraceptive methods should be taken at the same time within one to two months after wearing the ring to ensure 100% safety. Question: Do you know the best of both worlds (preventing pregnancy and preventing the spread of sexually transmitted diseases)?

E, the least accepted way of oral short-acting contraceptive (OC) : the success rate of 99.95% oral administration, mainly with progesterone, there are single small dose of progesterone or combined with estrogen two kinds. Generally, the first dose is taken from the 5th day of menstruation, one tablet every night for 22 days without interruption. If you miss it, just put it on the next morning. Vaginal bleeding will occur within 2 to 4 days after stopping the drug, and the next cycle is to continue taking the drug from the 5th day after the bleeding begins; If there is no bleeding within 7 days of stopping the drug, the next cycle of medication can also be continued. While nearly 80 percent of American women now use birth control pills, medicated contraception remains a less popular option for Chinese women. Chinese women do not like the reason is that estrogen will make a very small number of women have nausea, vomiting, dizziness and other early pregnancy reaction like performance, progesterone can make women feel no spirit. In fact, these reasons are often insufficient, because the chance of occurrence is very small and the degree is very slight. Long-acting oral contraceptives: the success rate of 96% to 98% are common compound (long-acting) L-18 methylnorethisterone and long-acting compound norethisterone chloride (a) degestrel 4. Take the first pill on the 5th day of your period, take the second pill 20 days apart (there are also 5-day intervals), and then take 1 tablet every 30 days. The reasons for not choosing, one is the large amount of hormones; Second, it has an accumulation effect, and the hormone effect can not be quickly subsided after stopping the drug. Long-acting contraceptive injection: success rate > 99.75% now can see more is made of long-acting progesterone and long-acting estrogen compound. Intramuscular injection once a month. The principle of their contraceptive effect is the same as that of OC, either so that the sperm can not enter the "city", or the sperm can not "see" the egg, or the fertilized egg has no "settling" place. If you do not have children and want to have children, it is best not to use, because it is easy to cause irregular menstruation. Subcutaneous implantation: contraceptive success rate of 99.9% Cut a half-centimeter mouth under the upper arm, fan into 2 or 6 small stick like contraceptive pill. Once implanted, it can last more than 5 years. However, a significant percentage of women experience irregular periods. If you plan to have children within a few years, you'd better not.
