What are the conventional contraceptive methods?

Many families nowadays do not want to have children so quickly, thinking that they are not ready for anything, so they do not want to have children so quickly. However, sometimes an unexpected pregnancy leads to a miscarriage, which is a very bad thing. Therefore, we can take contraceptive measures in advance to avoid accidental pregnancy. The following is a detailed introduction to conventional contraceptive methods, I hope you can understand it.

Secret 1: Weight plays a role. For women aged 18-39 who weigh 58 kg or more, oral contraceptives have a 60% chance of failure, especially those with low estrogen levels. Women who are overweight have a faster metabolism and need more hormones to prevent pregnancy. In addition, contraceptives have a lipolysis effect and may "stay" in the body where fat is stored, and cannot reach the bloodstream where they should be to really work. If you weigh more than 58 kg, it is best to ask your doctor to recommend other more reliable methods, such as intrauterine devices, or a combination of contraceptives and condoms to ensure that there is no risk of failure.

Secret 2: The most effective ones are the ones that have lasted a long time. In fact, there are many very effective contraceptive methods that you don't know about, have never imagined, and no one has recommended them to you. Are you curious? The intrauterine contraceptive device (IUD) is one of them. This is a small T-shaped contraceptive device that is inserted into the uterus. It is made of flexible soft plastic and must be inserted into the body by a doctor. After that, even if the egg has been fertilized, it will not implant and grow in the uterus. As long as there is nothing abnormal, you can leave it alone for one or two years, and it will not cause trouble for sex. It is very convenient. 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 has more or less affected the reputation of IUDs. Although it is quite common in other countries, less than 1% of women choose to use it. This situation is not optimistic, because for monogamous families, although the IUD cannot guarantee that you will not be infected with sexually transmitted diseases, it is indeed one of the most effective contraceptive measures. Once inserted, you can forget about its existence. Not only does it not have the hormonal side effects that other contraceptives may bring, but it is also extremely effective - with only a 1% failure rate per year. There are two types of IUDs, and the latest one is Mirena. As we know, there are more than 100 million sperm in the semen ejaculated by men. This mighty army swims scrambling in the female reproductive tract, swimming 2-3 mm per minute. After passing through the four major barriers of the vagina, cervix, uterine cavity and fallopian tubes,

Date with the egg. The principle of Mirena is to release progesterone into the uterus, making the cervical mucus thicker, making it difficult for sperm to penetrate the mucus and unable to continue moving up into the uterine cavity to meet the egg. It can be placed in the human body for at least 5 years. Another type is Paracard, which is made of copper. The sperm army does not hesitate to travel a long distance. After taking the medicine for a week, the contraceptive begins to work and swings its tail forward.

The force of the attack is overwhelming. Many sperms surround an egg, digest the zona pellucida around it, break through the cells surrounding the egg, dissolve the acid between the cells, and make way for the next sperm. The whole process of sperm and egg cell combination is fertilization. Paracard's tactic is to try to weaken the vitality of sperm and protect the egg from fertilization. It can be placed in the body for at least 10 years.

After removal, fertility returns to normal. If there is a flaw, it is that the uterus of women who have never given birth is not soft, so it is more 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 who has no history of sexually transmitted diseases, IUD is undoubtedly an ideal choice. However, the best IUD can fail due to incorrect placement or gynecological diseases. Women with a history of pelvic diseases are not recommended to use IUDs, as it may worsen bacterial infections. Other people who are not suitable: those with gynecological diseases such as extreme uterine retroflexion, endometritis, salpingitis, vaginitis, uterine fibroids, etc.; those with excessive menstrual volume 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 later than one week) → Ask the doctor to operate → Check once a year.

Secret 3: The hidden dangers of condoms Most condoms are made of nonoxynol-9, a spermicide. It is not only ineffective in preventing STDs, but may increase the risk of contracting AIDS and other STDs. Its working principle is to achieve the purpose of contraception by destroying the sperm cell membrane. In this process, the protective membrane on the edge of the vagina may also be destroyed. The US Food and Drug Administration believes that due to cell damage, the risk of contracting STDs with condoms is increased, and is considering putting a warning label on finished products containing spermicide ingredients. Use it properly to avoid future troubles

: Use your fingertips to pinch the small pocket at the top and remove the air inside. If there is air residue, the top will bulge and may fall off in the middle. Put it on the erect penis and open the curled part in circles. Do not roll into the pubic hair and do not have wrinkles. It is better to wear it from the beginning. Pay attention to the handling method after use. When pulling out, press the root and pull it out slowly, otherwise it may fall off in the vagina. If you do not leave the body for a while after ejaculation, the male genitals will shrink and there is a risk of leaking semen.

The above introduces some common contraceptive methods. For women, taking good contraceptive measures is also a good protection for themselves, because abortion is also very harmful to women. I hope it can help everyone in life, and I wish you all a happy life!
