The effect of tubal sterilization with the Pomeroy technique and bipolar electrocauterization on the ovarian reserve and serum anti-Müllerian hormone levels in a rat model

Abstract

Objective: To investigate the effects of tubal sterilization techniques on the ovarian reserve and serum anti-Müllerian hormone (AMH) levels in rats.

Study design: Wistar Hannover rats (n=21) were assigned to the following 3 groups (7 rats/group): Pomeroy technique, bipolar electrocauterization, and control. Pre- and postoperative serum AMH levels, ovarian damage and ovarian follicle counts were assessed.

Results: Total ovarian damage was higher in the electrocauterization group than in the Pomeroy (p=0.008) and control (p<0.0001) groups. The large antral follicle count was higher in the Pomeroy group than in the electrocauterization (p=0.023) and control (p=0.003) groups. The electrocauterization group had a greater decrease in postoperative serum AMH levels than the Pomeroy and control groups (p=0.031).

Conclusion: Bipolar electrocauterization may have a negative effect on the ovarian structure and ovarian reserve compared to the Pomeroy technique.
