Abstract:

An IUD placed in the uterine cavity that secretes levonorgestrel (LNG) at the rate of 20 mcg a day has been studied over the course of 14 years. In this contraceptive around a Nova T stem, covered with a silicon membrane. 20 mcg levonorgestrel is sufficient to produce 10 mcg, even after 5 years duration. During its use the duration and amount of menstruation decreases significantly. Therefore, blood hemoglobin and iron content is decreased. In spite of the amenorrhea, studies have shown that production of estrogen and ovary function have been normal. Both fertility and menstruation return quickly after the contraceptive is removed, generally after five years of use. The LNG device has proven very reliable. The pregnancy index during the five years of study was 0.4, and at least some of the pregnancies were caused by spontaneous expulsion of the contraceptive. If the menstrual flow returns to normal, there is reason to suspect that the IUD has come out. Headaches and acne are listed as common side effects associated with this method. It is mostly recommended for women over 30 who are in stable relationships and who want their fertility to return. LNG prevention does not protect against infections. Therefore, education is important for successful use of this method.
