 For patients who wish to avoid hormonal medications because of personal medical contraindications such as breast cancer, unacceptable side effects, or personal preference, tubal ligation offers highly effective birth control without the use of hormones.Occluding or removing both fallopian tubes decreases the likelihood that a sexually transmitted infection can ascend from the vagina to the abdominal cavity, causing pelvic inflammatory disease (PID) or a tubo-ovarian abscess.Tubal ligation does not completely eliminate the risk of PID, and does not offer protection against sexually transmitted infections.
