If a woman has already given birth and no longer wishes to have children, she may consider placing a birth control ring in the uterus for contraception. The cost of the IUD varies greatly depending on the type of ring, and the operation fee for the IUD is usually around$300. Since there are more types of rings, their prices will vary somewhat. For example, placing the most common uterine or T-shaped ring, the price of a simple ring is around$30-$50. If the ring is placed with medication, such as the placement of the IOM ring, the price of the ring will be slightly more expensive at$170 or more due to the indomethacin contained in the ring. If the woman herself has adenomyosis, then you need a levonorgestrel birth control device, which can play a role in contraception, but also inhibit endometrial hyperplasia, and play a role in reducing menstruation and relieve menstrual cramps, and this type of birth control ring is particularly expensive, its price is in the 1000 yuan or more. At the same time, before placing the birth control ring, you must first check the ultrasound to observe the size of the uterine cavity, and at the same time to do routine examination of the leukorrhea, in the absence of obvious inflammation before the ring can be placed.
