Menstrual pattern changes following minilap/Pomeroy, minilap/ring and laparoscopy/ring sterilization: a review of 5982 cases.

Menstrual pattern changes experienced by 5982 women subsequent to sterilization by the techniques of minilap/Pomeroy, minilap/tubal ring and laparoscopy/tubal ring were tabulated. Controlling for prior contraceptive use, we examined data on the following six menstrual parameters at the time of sterilization compared to reports at follow-up visits 6 and 12 months after surgery: cycle regularity, cycle length, menstrual flow duration, amount of flow, dysmenorrhea and intermenstrual bleeding. Our findings suggest that minilap sterilization does not cause menstrual pattern changes.
