What is tubal ligation primarily used for?

Tubal ligation is primarily used as a permanent method of contraception, which directly aligns with the goal of preventing pregnancy. The procedure involves surgically sealing, tying, or cutting the fallopian tubes to stop eggs from reaching the uterus for fertilization. This makes it an effective long-term solution for individuals seeking to avoid future pregnancies.

While cervical cancer treatment, temporary contraception, or alleviating pelvic pain involve different medical interventions or procedures, they are not the intended purpose of tubal ligation. This surgical procedure does not serve to treat cancer or directly address symptoms like pelvic pain, nor is it designed as a temporary measure for birth control. Therefore, the primary use of tubal ligation is indeed to prevent pregnancy.
