The Effect of Birth Control Methods on Anti-Mullerian Hormone (AMH) Levels

Overview

Anti-mullerian hormone (AMH) has been shown to be a reliable marker of ovarian reserve. In prior studies, tubal ligation has been shown to have an adverse effect on ovarian reserve. One theory postulated for this effect is that the ovarian circulation is disrupted by the procedure, leading to altered hormone production. In this prospective cohort study, the investigators plan to analyze the rates of AMH decline by comparing the following contraceptive methods: tubal ligation, Essure placement, and levonorgestrel intrauterine devices (IUDs).

Anti-mullerian hormone (AMH) has been shown to be a reliable marker of ovarian reserve because levels demonstrate a consistent age-related decline and do not fluctuate throughout the menstrual cycle. In prior studies measuring markers other than AMH, tubal ligation has been shown to have an adverse effect on ovarian reserve. The primary aim of this study will be to compare the rates of anti-mullerian hormone (AMH) decline following tubal ligation, Essure placement, and levonorgestrel IUDs, and then identifying any and all differences that these specific contraceptive methods have on the changes of AMH rates over time. The secondary aim will focus on analyzing the various types of tubal ligation methods (i.e. coagulation, ligation, clips, bands, etc.) to see if different techniques result in any difference in the rate of AMH decline. The hypothesis is that tubal ligation will result in an accelerated rate of AMH decline as compared to other long-term or permanent contraceptive methods.
