Long-term contraceptive methods for couples need to be judged according to gender. Women can take long-term contraceptive methods such as placing birth control rings, tubal ligation, and subcutaneous implantation of contraceptive pills, while men can take long-term contraceptive methods such as vasectomy. Women can have a birth control ring placed in the uterine cavity by a doctor 3 to 7 days after menstruation to achieve long-term contraception. For women who do not have the requirement to have children, they can take tubal ligation for contraception, which can prevent sperm and egg cells from meeting, thus achieving long-term contraception. Subcutaneous implantation of contraceptives refers to the placement of a certain amount of progestin in a silicon capsule tube, which is then implanted under the skin. Subcutaneous implantation of birth control pills can achieve the effect of long-term birth control pills by changing the consistency of cervical mucus and inhibiting the growth of the uterine lining. In addition, male patients are also able to achieve long-term contraception through vasectomy. Couples who want long-term contraception need to choose the appropriate contraceptive method under the guidance of a doctor. In addition, you can also take oral contraceptive pills or wear condoms and other methods of contraception.
