　　Subcutaneous implant contraceptive method is a new type of contraceptive method that has been promoted and used all over the world.

　　This contraceptive method places a certain dose of progesterone in a silicone capsule tube, and then buries the tube under the skin, allowing it to slowly release a small amount of progesterone, thus achieving a contraceptive effect. This kind of contraceptive was introduced in China in 1984 and was first used in Beijing, Shanghai, Tianjin, Shenyang and other cities. Currently, 15 provinces and cities across the country have established subcutaneous implants. clinical Experimental center performs this 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%.

　　The implant used in the subcutaneous implant contraceptive method consists of 6 matchstick-sized silicone capsule tubes. Each capsule tube contains 34 mg of L-18 A implant (also known as Noplan).

A small incision is made on the inner side of the contraceptive user's upper arm, and a special trocar is used to push 6 silicon capsule tubes from the incision into the subcutaneous (arranged in a fan shape). The operation ends here, and the incision does not need to be sutured. The entire operation can be completed within a few minutes.

If the wound is bleeding, infected or the silicone capsule tube prolapses, seek medical attention immediately. You can have sex 24 hours after surgery.

If you need to continue using this method of contraception, you can re-embed a set of silicone capsule tubes ； If you are planning to have a baby, take out the silicone capsule tube half a year before you plan to get pregnant.

　　About 20% of women experience menstrual irregularities such as irregular menstrual periods, prolonged menstrual periods, and increased menstrual blood volume during the initial period of use.； Some women also have amenorrhea. Most of the above-mentioned phenomena can gradually improve after half a year.
