There are many different methods of contraception, including long-acting and short-acting birth control pills, intrauterine devices, contraceptive injections, penis condoms, ligation, etc. Among them, the penis condom has the least side effects and can be said to have no side effects. The contraceptive rate can reach 93%-95% when the penis condom is used correctly. Not only does it have a contraceptive effect, but it can also serve to prevent the spread of sexual diseases. The intrauterine device may cause irregular vaginal bleeding, mainly in the form of increased menstrual flow, prolonged periods, and a small amount of spotting bleeding, which usually recovers gradually after 3-6 months. The effect of the contraceptive pill mainly causes amenorrhea, early pregnancy-like reaction, weight gain, and irregular vaginal bleeding. Patients who do not have fertility requirements may opt for ligation.
