During the 1970s, tubal sterilization became an important method of fertility control in the United States. Over the same period laparoscopy emerged as an important innovation, one that has been associated with both a shift from postpartum to interval sterilization and a dramatic decrease in length of hospital stay required for sterilization. The use of laparoscopy has also been associated with an increase in hospital-based outpatient sterilization, particularly in the West. The number of sterilizations performed in hospitals and the use of laparoscopy for interval sterilization in hospitals both appear to have peaked. The laparoscope is an example of a technologic advance that has reduced medical care costs.
20世纪70年代，输卵管绝育术成为美国控制生育的一种重要方法。同一时期，腹腔镜检查作为一项重要创新出现，它与从产后绝育向非孕期绝育的转变以及绝育所需住院时间的大幅缩短都有关联。腹腔镜检查的使用还与医院门诊绝育的增加有关，尤其是在西部。医院进行的绝育手术数量以及医院用于非孕期绝育的腹腔镜检查的使用似乎都已达到峰值。腹腔镜是一项降低医疗成本的技术进步的典范。
