The best method of contraception after marriage needs to be chosen according to the couple’s requirements for the timing of the birth of a child and whether there has been a need to have children in the past. For women who want to have children within the past 1-2 years, they can choose external condom or drug contraception, that is, short-acting oral contraceptive pills, which are generally safer, more effective, more convenient, and more reproducible, and the impact on their sex life is not particularly large, so both men and women can accept them. For patients who have already given birth to two babies and do not have the requirement for a birth plan, they can also choose the IUD. For the choice of IUD, there are copper-containing IUD and copper-free IUD, according to whether the patient has contraindications, to choose the appropriate contraceptive device. For women with combination of increased menstrual flow, adenomyosis and endometriosis, they can also choose Mannix Ring to achieve contraceptive effect. At present, no contraceptive measure can achieve 100% effective contraception, so for contraception after marriage, it is necessary to make a comprehensive choice according to whether both spouses have immediate or long-term plans to have children, as well as whether the woman has a combination of prohibited measures.
