The effects of tubal sterilization on menopausal age in a cohort of postmenopausal women.

Abstract

Objectives: To evaluate whether tubal sterilization (TS) has an adverse effect on menopausal age in a cohort of postmenopausal women. Study design: The medical records on TS were gathered from 1,228 postmenopausal women in menopause clinic at a tertiary hospital.

The ever use of intrauterine device rate was significantly lower in TS group than in non-TS group (P
