Long-term luteal changes after tubal sterilization

In this study the luteal function was evaluated in 109 subjects 2 to 108 months following tubal sterilization by Pomeroy's technique or laparoscopic tubal rings. Midluteal endometrial biopsies determined by basal body temperature charts were performed and dated in all subjects. Midluteal serum progesterone was estimated by RIA in 40 women. Our results indicated that the mean time which had elapsed since sterilization was significantly shorter in the subjects who revealed luteal defects than in those with normal luteal function. There were no statistically significant differences between the 2 occlusive techniques in terms of poststerilization incidence of luteal defects.
