Question 1

What is the Meaning of LNG-IUS?

Accepted Answer

LNG-IUS stands for Levonorgestrel-Releasing Intrauterine System. It is a small, T-shaped plastic device containing a reservoir of levonorgestrel, a synthetic progestin, designed for placement within the uterine cavity. This system offers long-acting reversible contraception and therapeutic benefits for various gynecological conditions.

Question 2

What is the Context of LNG-IUS?

Accepted Answer

The LNG-IUS operates directly within the female reproductive system, specifically the uterus. Its localized hormone delivery minimizes systemic circulation, thereby reducing potential systemic hormonal side effects while primarily affecting the endometrium and cervical mucus. This makes it a highly targeted endocrine intervention.

Question 3

What is the Significance of LNG-IUS?

Accepted Answer

This device holds substantial importance in clinical practice due to its high contraceptive efficacy and significant non-contraceptive benefits. It effectively manages heavy menstrual bleeding, a common gynecological concern, and offers a viable treatment for endometriosis-related pain. Its long duration of action contributes to improved patient adherence and reduced unintended pregnancies, positively impacting reproductive health outcomes.

Question 4

What is the Mechanism of LNG-IUS?

Accepted Answer

The LNG-IUS continuously releases levonorgestrel directly into the uterine cavity. This localized hormone primarily induces endometrial atrophy, thinning the uterine lining and making it unsuitable for embryo implantation. It also thickens cervical mucus, impeding sperm passage, and may suppress ovulation in some individuals, though this is not its main contraceptive action.

Question 5

What is the Application of LNG-IUS?

Accepted Answer

Clinically, the LNG-IUS is utilized for contraception, typically effective for periods ranging from three to eight years depending on the specific device. Healthcare providers also prescribe it for the management of menorrhagia, dysmenorrhea, and as a component of hormone replacement therapy to protect the endometrium in women receiving estrogen. Insertion is an office-based procedure performed by trained medical professionals.

Question 6

What is the Metric of LNG-IUS?

Accepted Answer

The effectiveness of the LNG-IUS is primarily assessed through clinical outcomes such as the absence of pregnancy and a reduction in menstrual blood loss. Patient-reported symptom improvement, particularly regarding pain associated with endometriosis or heavy bleeding, serves as a key indicator of therapeutic success. While systemic hormone levels are low, direct measurement is not routinely used to monitor its efficacy or local action.

Question 7

What is the Risk of LNG-IUS?

Accepted Answer

Potential risks associated with the LNG-IUS include insertion-related complications such as uterine perforation, infection, or expulsion. Some individuals may experience hormonal side effects like irregular bleeding patterns, ovarian cysts, or mood changes, especially during the initial months after insertion. It is contraindicated in cases of active pelvic inflammatory disease, certain gynecological cancers, or known hypersensitivity to its components.
