Women were used as their own controls in the comparison of presterilization and poststerilization menstrual patterns. Five parameters were studied: regularity of cycle length, duration and amount of flow and incidence of dysmenorrhea and intermenstrual bleeding. Three parameters in the electrocoagulation group (regularity of cycle length and duration and amount of flow) and one parameter in the tubal ring group(duration of flow) showed significant changes after sterilization. However, by controlling for the effect of previous contraceptive methods used, no significant menstrual pattern changes following sterilization were discerned in either technique group.
在比较绝育术前和术后的月经模式时，女性自身作为对照。研究了五个参数：月经周期长度的规律性、月经量和持续时间、痛经发生率以及经间期出血情况。电凝组的三个参数（月经周期长度的规律性、月经量和持续时间）和输卵管环组的一个参数（月经量持续时间）在绝育术后显示出显著变化。然而，通过控制先前使用的避孕方法的影响，在任何一个技术组中均未发现绝育术后月经模式有显著变化。
