There is no such thing as the best method of long-term contraception for couples, and it depends on whether the couple has any reproductive requirements; currently, the commonly used contraceptive methods include the contraceptive pill, condom, birth control ring and ligation. 1. Contraceptive pill: It is mainly used to achieve the purpose of contraception by inhibiting ovulation or resisting the implantation of pregnancy sacs. If both parties have the desire to have children, they can consider taking contraceptive pills to achieve the purpose of contraception. Such drugs should be taken under the guidance of a doctor. 2. Condom: If you are not allergic to rubber, this is the safest and easiest contraceptive measure available. Anyone who is not allergic can use it. 3. Birth control ring: If both parties do not want to have children in a short period of time, you can also consider placing a birth control ring to achieve the purpose of contraception. However, the birth control ring may shift or fall off, so it needs to be checked regularly. 4. Ligation: It includes female tubal ligation and male vasectomy. It is suitable for couples who have no requirement for childbearing. For couples who need long-term contraception, there is no such thing as the best method, and they should choose the suitable contraceptive measures for themselves under the guidance of doctors.
