There is no doubt that the use of contraceptives is still harmful, but don't worry too much. Many people have misunderstandings about oral contraceptives. I believe that since it is a manufactured drug, it will not cause great harm to the body ... One of the misunderstandings: taking oral contraceptives for a long time is harmful to the body, and it is best not to take it for more than 5 years or 10 years at a time? This view is wrong. There is no clinical research data showing that women who have no contraindications to oral contraceptives (see the instructions for oral contraceptives) will have serious adverse reactions after taking oral contraceptives for a long time. Many foreign women insist on oral contraceptives until menopause. The estrogen content of modern oral contraceptives is only 30 micrograms or 20 micrograms, which minimizes the occurrence of estrogen-related side effects (nausea, headache, breast tenderness, etc.). ). These side effects, if they occur, can disappear by themselves after 3 months of oral contraceptives. And the quality of progesterone in oral contraceptives has been greatly improved. New progestogens, such as deoxyprogesterone in Marvelon, are particularly selective and have little affinity for androgen receptors. Rare androgen-like side effects (acne, hirsutism, weight gain, abnormal lipid metabolism and glucose metabolism, etc. ). Oral contraceptives are not only harmless to the body, but many clinical data show that long-term use of oral contraceptives can also have certain short-term and long-term benefits to the body, such as: improving the symptoms of menstrual disorders (excessive menstrual blood, long menstrual period and menstrual pain); Reduce the incidence of ovarian cancer, endometrial cancer, benign breast hyperplasia and some gynecological diseases such as pelvic inflammatory disease, ectopic pregnancy and osteoporosis. Therefore, oral contraceptives can be taken for a long time as long as they are monitored regularly (such as annual physical examination). Myth 2: After using any kind of oral contraceptives, do you need to stop taking drugs for 3-6 months before you can plan pregnancy? This view is only for long-acting oral contraceptives. For short-acting oral contraceptives, there is no domestic and foreign clinical research data to prove that it is necessary to stop using short-acting oral contraceptives for 3-6 months before planning pregnancy. Long-term large-scale animal and clinical studies of modern oral contraceptives, such as Mafuron produced by Organon Company in the Netherlands, have proved that Mafuron has no adverse effects on mother and baby after withdrawal. If pregnancy is considered, it is generally recommended to stop using Marvelon 1 month and wait until menstrual cramps recover (which helps to calculate the expected date of delivery), instead of waiting for 3-6 months. So, mom, Long Fu? Especially suitable for newlyweds. Myth 3: taking oral contraceptives for a long time will affect women's fertility and may lead to female infertility, so after taking oral contraceptives for a period of time, you should stop and rest for a while? This concept is wrong. There is no clinical data showing that women's fertility will be inhibited after taking oral contraceptives for a long time. Experts believe that oral contraceptives have no adverse effects on fertility, and even think that oral contraceptives have beneficial effects on women's fertility, because oral contraceptives can reduce the probability of pelvic inflammatory disease, uterine cancer and ovarian cancer, and these diseases will reduce women's fertility or make women completely lose their fertility. In a word, oral contraceptives are a reversible contraceptive measure, and women's fertility can be restored after stopping taking them. The recovery of fertility has nothing to do with the time of taking oral contraceptives. Myth 4: Can taking oral contraceptives lead to side effects such as obesity and acne? In the past, oral contraceptives had endogenous androgen-like effects, so after taking these oral contraceptives for a long time, the body would have androgen-like side effects such as obesity and acne. Modern oral contraceptives, such as Marvelon, contain highly selective progesterone and have little affinity for androgen receptors. Therefore, after taking modern oral contraceptives, there are few androgen-related side effects such as weight gain, hirsutism, seborrheic dermatitis and acne, which are common in oral contraceptives. Clinical data show that 80% of women have completely disappeared after taking Marvelon for 6 months. Estrogen in oral contraceptives may cause nausea, headache and breast pain in some women. Of course, the hormone dose is low and the incidence rate is reduced. Modern oral contraceptives (such as Marvelon) have a low dose of estrogen (only 30 micrograms) and the incidence of side effects is about 2-8%. After 6 months, the overall incidence rate is usually lower than before taking it. Myth 5: Long-term use of oral contraceptives will definitely lead to amenorrhea? Postmenopausal amenorrhea (PPA) refers to amenorrhea for more than 6 months after stopping taking oral contraceptives. Experts suggest that the term amenorrhea (PPA) should be abolished. Because most experts believe that there is no causal relationship between taking oral contraceptives and amenorrhea. Amenorrhea after oral contraceptives has nothing to do with the types and taking time of oral contraceptives. Because the appearance of secondary amenorrhea is related to many factors, such as premature ovarian failure, polycystic ovary syndrome and other diseases. Experts suggest that all secondary amenorrhea (amenorrhea lasting more than 6 months) should be treated by a doctor. It is generally believed that if you want to get pregnant after taking oral contraceptives, you should wait 3-6 months after stopping taking them (during which other contraceptive measures are taken) before getting pregnant. You don't need to take Marvelon. If you want a child, stop taking it. It is generally recommended to stop using Marvelon for one month, and then consider pregnancy after natural menstruation resumes, which is helpful to calculate the expected date of delivery. Ovulation can be resumed after stopping using Marvelon, and Marvelon itself will not affect the fetus and mother.
