A woman who has her IUD removed at the age of 45 still has a chance of getting pregnant, and the likelihood of pregnancy is related to her ovarian reserve function, which varies from person to person. The average age of women at menopause is 49.5 years old. After 40 years old, a woman gradually enters the perimenopausal period, and her ovarian reserve function gradually decreases, but if she removes the IUD before menopause, she may still be able to get pregnant, and the higher the value of AMH, the higher the chances of pregnancy. The best time to remove a woman’s birth control device is within 1 year of menopause. If there is still a possibility of pregnancy if the IUD is removed before menopause, it is recommended that contraception be used through condoms, birth control pills, etc., to avoid the harm brought about by an unwanted pregnancy. The best time to remove the IUD is between 3-7 days after menstruation without intercourse. Before removing the IUD, an ultrasound examination should be done to check the type and location of the device. After removing the IUD, you should pay attention to rest, keep the vulva clean and hygienic, and prohibit sexual intercourse and tub baths for two weeks to prevent infection. There may be a small amount of vaginal bleeding after IUD removal, usually not more than 7 days. Any discomfort after the removal of the IUD should go to the hospital in time.
