Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

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).
