What does the abbreviation BTL stand for?

• A. Bilateral Testicular Ligation
• B. Bilateral Tubal Ligation
• C. Bilateral Uterine Ligation
• D. Bilateral Tracheal Ligation

Answer: (B)

BTL stands for Bilateral Tubal Ligation. This is a female permanent sterilization procedure in which both fallopian tubes are blocked, cut, or sealed to prevent sperm from reaching the egg and thereby prevent fertilization. Methods include tubal clips, rings, cauterization, or occlusion performed via laparoscopy or similar approaches. The other options describe different structures or procedures that are not standard for contraception: the terms referring to male sterilization or to an unrelated part of the body. In medical notes, BTL is a common way to document that bilateral tubal ligation has been performed or is planned.
