There are many kinds of contraceptives for women in their 40s, the common ones are intrauterine devices (IUDs), metal copper ion implants, and imported Mannedal, which can last for five, 10, 15, or 20 years, which are relatively simple and effective. In addition, if a man is willing to use a condom, he can also use a condom for the whole period of contraception. If the condom is used at the time of ejaculation, there is still a possibility of accidental pregnancy. Another good contraceptive method is the subcutaneous implantation of a birth control device, but it contains a large dose of progestin, which may affect a woman’s menstruation and lead to spotting and bleeding, or amenorrhea. Tubal ligation can also be used if a woman does not have fertility requirements, and male vasectomies can be performed in men.
