Contraceptive secrets every Spring Festival couple must know

　　Secret 1: Weight plays a role

　　Between the ages of 18 and 39 female , if the weight is equal to or greater than 58 kilograms, oral contraceptive pills are 60% likely to fail, especially those with low estrogen levels. Women who are overweight have a faster metabolism and require more hormones to prevent conception. Moreover, birth control pills have a fat-dissolving effect and may "stay" in the places where fat is stored in the body, unable to reach the bloodstream where they should be to actually take effect. If you weigh more than 58 kilograms, it is best to ask your doctor to recommend other more reliable methods, such as intrauterine devices, or a combination of birth control pills and condoms to ensure that everything is foolproof.

　　Secret 2: What lasts is the most effective

　　In fact, there are many very effective contraceptive methods that you are not aware of, that you have never imagined, and that no one has recommended to you. Are you curious - the intrauterine device is one example.

　　Generally speaking, today's IUDs are quite safe. Only one brand called "Dalkson Shield" once had deviations and "disappeared" from the market in the 1970s, but it still affected the reputation of IUDs to some extent. Although the IUD is quite common in some countries, less than 1% of women choose to use it. This situation is not optimistic, because for monogamous families, although the intrauterine device cannot guarantee that you will not contract sexually transmitted diseases, it is indeed the most effective contraceptive method. Once inserted, you can forget about its existence. Not only does it have no hormonal side effects that other contraceptive pills may cause, but it is also extremely effective - only a 1% failure rate.

　　There are two types of IUDs, the latest being Mirena. As we know, male More than 100 million ejaculated semen sperm , this mighty army is rushing to swim in the female reproductive tract. It can swim 2 mm to 3 mm per minute, passing through the vagina, Uterus After the four major passes of the cervix, uterine cavity and fallopian tube, the date is reached with the egg. The principle of Mirena is to release gestin into the uterus, which thickens the cervical mucus, making it difficult for sperm to penetrate the mucus and continue to ascend into the uterine cavity to meet the egg.

　　It can stay in the body for at least 5 years. The other type is Paracard, made of copper. Regardless of the long distance, the sperm army swings its tail forward persistently, and the oncoming force can be described as menacing. Many sperm surround an egg, digest its peripheral zona pellucida, break through the cells surrounding the egg, dissolve the acid between the cells, and open the way for the next sperm. The entire process of the combination of sperm and egg cells is the formation process of a fertilized egg.

　　Paracard's strategy is to try to weaken the sperm's motility and protect the eggs from fertilization. It can be left in the body for at least 10 years. After removal, fertility returns to normal. If there is any flaw, it is that the uterus of women who have never given birth is not soft, it is difficult to place it, and there is occasional pain, but only in the first few months. Also, during menstruation, the pain in the lower abdomen and waist may be slightly more severe than before. If you have a regular sexual partner and the other person does not sexually transmitted diseases History, IUD is undoubtedly the ideal choice. However, the best birth control ring may be damaged due to incorrect placement or Gynecology disease , will also fail. IUD use is not recommended for women with a pelvic history as it may worsen bacterial infections.

　　Other unsuitable groups: those with extreme uterine retroflexion, endometritis, salpingitis, Vaginitis , uterine fibroids and other gynecological diseases, and those with excessive menstrual flow and secretions.

　　Correct operation: Check with a doctor → Determine whether it is suitable → Choose the shape → Choose the time (a few days after menstruation, no more than one week at the latest) → Ask the doctor to operate → Check once a year.
