Changes in menstrual blood loss after four methods of female tubal sterilization

Abstract

One-hundred females requesting tubal sterilization were included in this study. They were enrolled into 4 groups, each n = 25. They were allocated to a particular method of sterilization on a randomized basis. The four modalities used were: laparoscopic Falope ring application, bipolar electrocoagulation, Hulka clip application and Pomeroy tubal ligation via minilaparotomy. The menstrual blood loss (MBL) was quantitatively estimated, using the alkaline hematin method, prior to sterilization and after 3, 6 and 12 months. No significant changes in MBL were observed after the four sterilization techniques. Moreover, they did not differ significantly in this context.
