Why Sterilization (Tubal Ligation) Is Not Performed During Menstruation

Tubal ligation (female sterilization) is typically scheduled outside the menstrual period.

Reasons

• Cervical Changes: During menses, the cervix is softer, lower, and slightly dilated → harder to manipulate with uterine manipulator (used for laparoscopic tubal access); higher perforation risk.
• Infection Risk: Menstrual blood is a culture medium; ascending infection risk during transcervical instrumentation or laparoscopy (if spillage).
• Visualization: Blood obscures pelvic view during laparoscopy/minilaparotomy.
• Patient Discomfort: Baseline menstrual cramps + surgical pain = worse postoperative pain.
• Pregnancy Exclusion: While menstruation confirms non-pregnancy, a urine hCG test is standard pre-op regardless.

Optimal Timing

• Follicular phase (days 5–10 of cycle): Thin endometrium, minimal bleeding, low pregnancy risk, good visualization.
• Postpartum (during C-section or 6+ weeks vaginal delivery): Convenient, uterus still enlarged for minilaparotomy.
• Interval (any time with confirmed negative hCG).

Vasectomy (Male Sterilization)

No cycle timing issues; performed anytime.
