Women who need contraception and who suffer from certain gynecological conditions are suitable for the Mannuelle IUD. The Mannuelle ring is a drug-containing intrauterine device (IUD), also known as a levonorgestrel IUD, which can inhibit ovulation and stop bleeding by releasing a small amount of the drug every day, and is usually used for 5 years. However, menstrual changes may occur after placing the Mannix IUD, manifested as spotting bleeding, reduced menstrual flow, or even amenorrhea, which will usually resolve on its own in 3-6 months. 1. Contraceptive needs: For women in their childbearing years who have a need for contraception, they can have the Mannuelle Ring placed. 2. Certain gynecological diseases: such as excessive menstruation, dysmenorrhea, endometriosis, adenomyosis, endometrial hyperplasia including simple hyperplasia and complex hyperplasia, and endometrial polyp removal after the placement of the IUD has the effect of preventing recurrence. Mannuelle ring needs professional doctor’s evaluation before placing, and contraindications such as gynecological inflammation and bleeding need to be ruled out before placing. A small amount of uterine bleeding within 3 months after the placement of the IUD is normal. If the bleeding time after the placement of the IUD exceeds 3 months, or if the bleeding is heavy and accompanied by obvious discomfort, it suggests that the IUD is not adapted to the situation, and it is recommended that you seek medical attention in time, and receive further treatment under the guidance of your doctor.
