| Use: | AMH is used for the assessment of the ovarian reserve in women presenting to fertility clinics. This system is intended to distinguish between women presenting with AFC (antral follicle count) values > 15 (high ovarian reserve) and women with AFC values ≤ 15 (normal or diminished ovarian reserve). This system is intended to be used for assessing the ovarian reserve in conjunction with other clinical and laboratory findings before starting any fertility therapy. It is not intended to be used for monitoring of women undergoing controlled ovarian stimulation in an Assisted Reproduction Technology program.
Serum AMH levels have been shown to be relatively stable during the menstrual cycle with substantial fluctuations being observed in younger women. AMH levels further demonstrate lower intra- and inter-cyclic variation than baseline FSH. Serum AMH levels decrease significantly during the use of combined contraceptives. Measurement of serum AMH is clinically used for assessment of ovarian reserve reflecting the number of antral and pre-antral follicles, the so-called antral follicle count (AFC). |
