The statement of the safest and most effective contraception is inappropriate. Common contraceptives include condoms, birth control pills, intrauterine devices (IUDs), tubal ligation, extracorporeal spermatozoa, and subcutaneous implantation of contraceptives. Contraception means measures to prevent a woman from being impregnated during sexual intercourse. Although, there are many types of contraception, there is no such thing as the safest and most effective contraception. Usually, the common contraceptives in life are condoms, birth control pills, ejaculation, intrauterine device, and so on. Among them, condoms can be categorized into male condoms and female condoms, which are physical isolation. Apart from that, the less common contraceptives are tubal ligation and subcutaneous implantation contraception. Contraception can not only carry out family planning, but also block the transmission of sexually transmitted diseases, therefore, it is necessary to correctly adopt contraceptive measures in daily life. To summarize, for those who have no birth plan, they must adopt safe and effective contraceptive measures for self-protection. If you have any other questions, it is recommended to consult a professional doctor for guidance.
