Does Birth Control Affect AMH Levels?

Most studies suggest that AMH levels are not significantly altered by hormonal birth control methods like pills, patches, or IUDs. AMH reflects the ovarian reserve, which remains stable regardless of active ovulation suppression by contraceptives. However, some research indicates that long-term use of hormonal birth control may slightly lower AMH readings, although this does not necessarily reflect a true decline in ovarian reserve. Women considering AMH testing while on birth control should consult their doctor for accurate interpretation of results. Discontinuing birth control for a short period may provide a more precise assessment of ovarian function if required.
