Levonorgestrel-Releasing IUD

Meaning

A Levonorgestrel-Releasing IUD is a highly effective, long-acting reversible contraceptive device that is placed directly into the uterus, where it locally releases the synthetic progestin levonorgestrel. This device functions primarily by causing changes to the cervical mucus, endometrium, and tubal motility, creating an environment inhospitable to sperm and implantation. Beyond contraception, its localized hormonal effect makes it a valuable therapeutic option for managing gynecological conditions such as heavy menstrual bleeding and endometrial hyperplasia, demonstrating a precise application of endocrinology in reproductive health.
