What is ovarian reserve testing? Ovarian reserve—a fancy word for egg count—testing typically takes the form of an AMH, or anti-Mullerian hormone, blood test and an antral follicle count. AMH is a protein hormone produced by cells inside the ovarian follicles; the level of AMH in the blood can help doctors estimate the number of follicles inside the ovaries.
An antral follicle count, on the other hand, is performed by a doctor during an ultrasound. Older, and generally less accurate, methods of measuring ovarian reserve include FSH, estradiol, and inhibin testing on the third day of the menstrual period. FSH, or follicle-stimulating hormone, is a chemical that helps the ovarian follicle become mature and release an egg. Learn more about egg count.
These tests have been called critical and important by many fertility advocates and medical professionals. But in a recently published study of women attempting to get pregnant, researchers determined that women with low AMH levels less than 0. But the other—and for purposes of natural fertility, more important—factor in whether a woman can get pregnant, stay pregnant, and deliver a healthy baby is egg quality.

Stimulation was continued till there were at least follicles of 18 mm. These follicles were assessed by color Doppler for their physiological maturity. Ovum pick up was done h after hCG.
For both groups the primary end point was number of follicles larger than 12 mm seen on the day of hCG. The final end point was the number of ova retrieved on ovum pick up. This value is higher than the tabulated one-tailed significance value 0. This indicates that for PCO group though AFC and AMH can be correlated with the total number of follicles larger than 12 mm diameter on the day of hCG, both have independent significance for estimation of number of follicles that would grow to a diameter larger than 12 mm on the day of hCG.
Results in Table 3 clearly confirm that both AFC and AMH despite having positive and high correlation are yet critical as the level of difference between values of correlation is significant as indicated by z value for both the groups.
This is significant at 0. This value is almost same as the tabulated one-tailed significance value 0. For non-PCO groups as the z score value is higher than one-tailed significance value, but lower than two-tailed significance value; this infers that though AMH may increase the accuracy of estimation of number of ova retrieved on OPU over AFC, this difference is not highly significant.
This can be decided only by proper assessment of ovarian reserve before commencing ovarian stimulation. Various tests have been tried at different times for assessment of ovarian reserve like S.
Comparison of anti-mullerian hormone and antral follicle count for assessment of ovarian reserve
AMH and AFC have been shown to be the most sensitive ones for assessment of ovarian reserve in these studies. AFC and ovarian volume provide direct measurements of ovarian reserve, while AMH, inhibin B and oestradiol are released from growing follicles and so their levels reflect the size of developing follicle cohort. Inversion mode is most convenient method for counting antral follicles when they are multiple. Studies have been done to compare the accuracy and reliability of AFC and AMH for prediction of low response or for prediction of ovarian hyperstimulation.
Serum AMH levels have been shown to strongly correlate with the number of antral follicles[ 67 ] and have appeared to be cycle independent. This implies that the best poor response predictor to date, AFC,[ 10 ] has obtained company from a test that may have some crucial advantages.
This implies that AFC can predict the response of ovary to stimulation and can be used for selection of individual cycle for ovulation induction, but adding AMH also allows to assess the quality of the resultant ova and embryo. Both alone or in combination have a similar predictive power.
Combination of both tests do not significantly increase the predictive power. But assessment of both as predictor for normal response or for hyperstimulation has been done only in a few.
The purpose was to decrease the number of tests that a patient undergoing ART, has to take, to decrease the stress as well as financial burden, without compromising with the information gained. AFC therefore may be thought of as a single test for assessment of ovarian reserve. As the ultimate end result is ova retrieved on OPU, it can be concluded that for both groups, AFC alone may suffice as a test for estimation of ovarian reserve. This is so because the z values for both non-PCO as well as PCO group is equal to or below the tabulated one-tailed significance value.
