Tube implantation is also called subcutaneous implantation, which is clinically effective. It is a contraceptive method commonly used in clinical practice, which mainly involves putting an appropriate amount of progestin in a capsule tube and then burying it under the skin of women to achieve the effect of contraception by releasing progestin inside the tube, which can basically play a 100% contraceptive role. Although this method is effective, it may cause side effects, such as menstrual cycle disorders, irregular vaginal bleeding, and even amenorrhea. However, this method is not suitable for women with chronic diseases, such as diabetes, nephritis, hepatitis, etc.
