Question 1

What is the Meaning of Levonorgestrel-Releasing IUD?

Accepted Answer

A Levonorgestrel-Releasing Intrauterine Device (L-IUD) is a small, T-shaped plastic device inserted into the uterus. It continuously releases synthetic levonorgestrel, primarily serving as highly effective long-acting reversible contraception and also utilized for managing heavy menstrual bleeding and endometriosis-related pain.

Question 2

What is the Context of Levonorgestrel-Releasing IUD?

Accepted Answer

The L-IUD functions locally within the female reproductive tract, specifically the uterine environment. Its hormonal influence directly impacts the endometrium and cervical mucus. Systemic progestin absorption remains minimal compared to oral hormonal therapies, localizing its therapeutic and contraceptive actions within the uterus.

Question 3

What is the Significance of Levonorgestrel-Releasing IUD?

Accepted Answer

This device offers substantial clinical importance due to its exceptional contraceptive efficacy, consistently over 99% effective. It provides significant relief for individuals experiencing menorrhagia by reducing menstrual blood loss, often improving iron stores and quality of life. Its long-term duration, typically three to eight years, alleviates daily adherence burdens, making it a valuable option.

Question 4

What is the Mechanism of Levonorgestrel-Releasing IUD?

Accepted Answer

The mechanism involves continuous, localized levonorgestrel release into the uterine cavity. This targeted delivery induces physiological changes, including marked endometrial thinning, rendering it unsuitable for embryo implantation. Concurrently, the progestin thickens cervical mucus, impeding sperm passage into the upper reproductive tract, thus contributing to contraception.

Question 5

What is the Application of Levonorgestrel-Releasing IUD?

Accepted Answer

The L-IUD is inserted into the uterus by a qualified healthcare professional during a routine clinical visit. It serves as a suitable long-term contraceptive choice for many individuals. Beyond contraception, clinicians frequently prescribe this device for managing dysfunctional uterine bleeding, dysmenorrhea, or as hormonal therapy for specific gynecological conditions.

Question 6

What is the Metric of Levonorgestrel-Releasing IUD?

Accepted Answer

Contraceptive effectiveness is quantified using the Pearl Index, reflecting pregnancies per 100 woman-years of use. For therapeutic indications, improvements in menstrual blood loss are assessed using pictorial blood loss assessment charts. Reductions in pelvic pain are evaluated through patient-reported symptom scales. Long-term success is gauged by patient satisfaction and continuation rates.

Question 7

What is the Risk of Levonorgestrel-Releasing IUD?

Accepted Answer

While generally well-tolerated, potential risks warrant careful consideration. Contraindications include active pelvic inflammatory disease, certain uterine anomalies, or unexplained vaginal bleeding. Common initial side effects may include irregular bleeding patterns, ovarian cysts, headache, or breast tenderness. Rare but serious complications, such as uterine perforation during insertion or ectopic pregnancy if conception occurs, necessitate prompt medical attention.
