What is the egg timer test?

This test aims to estimate the numbers of ovarian follicles and eggs present in the ovary at a given time. Some people consider that an AMH test alone is enough. For the reasons explained above, it can be misleading to use AMH values alone to estimate egg numbers. A more comprehensive evaluation involves an AMH test as well as an ultrasound scan performed by a highly trained fertility expert to measure the antral follicle count. For the reasons detailed in the above sections, the egg timer test can estimate egg numbers but is not a reliable predictor of fertility potential.
