Which contraceptive method is the best and safest?

Many residential areas or communities distribute free condoms to facilitate residents' use. Of course, it is also a way to promote contraception. In fact, contraception is very simple and the method is not complicated. It is just that you have to distinguish between men and women when using contraception, which will make a big difference in contraception. But we need to choose the safest contraception to prevent unwanted pregnancies. So which contraceptive method is the best and safest?

The principle of IUD

The mechanism of human pregnancy is that the female ovary releases an egg, the egg is fertilized in the ampulla of the fallopian tube, and then develops into an embryo (morula) in the fallopian tube. The embryo is then released into the uterus to implant and grow. Contraception is about blocking any of these steps.

The contraceptive principle of the IUD is: when an embryo wants to implant in the uterus, the constantly moving IUD scrapes the uterine wall, causing aseptic inflammation of the uterus, making it impossible for the embryo to implant normally in the uterus and conceive, thus causing miscarriage to achieve the purpose of contraception. The essence of an intrauterine contraceptive device (IUD) is a long-term, mild abortion procedure using curettage and abortion, and it is the first choice for post-marriage contraception for Chinese women.

Subdermal contraceptive implant

Subcutaneous contraceptive implant is a new contraceptive method that is currently being promoted and used throughout the world. This contraceptive method is to put a certain dose of progesterone in a silicon capsule tube, and then bury the tube under the skin, so that it slowly releases a small amount of progesterone, thereby playing a contraceptive role. In 1984, my country introduced the subcutaneous implant contraceptive method, which was first used in cities such as Beijing, Shanghai, Tianjin and Shenyang. Currently, 15 provinces and cities across the country have established subcutaneous implant clinical trial centers to perform subcutaneous implant contraceptive surgery. According to relevant statistics, the pregnancy rate within 2 years is only 0.1%, and the pregnancy rate within 3 years is 0.24%.

Subcutaneous contraceptive implants achieve the purpose of contraception by changing the viscosity of cervical mucus, preventing sperm from entering the uterine cavity; inhibiting the growth of the endometrium, which is not conducive to the implantation of the fertilized egg; and inhibiting ovarian ovulation.

Cervical cap

The cervical cap is made of an elastic metal ring covered with a hemispherical thin rubber diaphragm. The outer diameter of the spring coil is 50 mm, which is No. 50. There are 7 other models such as 50, 55, 60, 65, 70, 75, and 80. Chinese women generally use three sizes: 65, 70 and 75.

Mechanism of action: The cervical cap itself and the spermicidal cream applied before insertion act as a barrier to block sperm, preventing sperm from meeting and combining with the egg. The spermicidal cream can also kill sperm or reduce sperm motility.

Which contraceptive method is the best and safest? There are many safest contraceptive methods, mainly suitable for women. Surgical contraception is to cut off the vas deferens and fallopian tubes. Once you want to get pregnant again, it will be difficult. You must think carefully when using such contraception. The operation cannot be reversed. Contraception is to prevent women from having abnormal children. Multiple births are also restricted by the law, so we must obey relevant instructions and not get pregnant or use contraception blindly.
