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.
