Ovarian reserve

An estimate of how many eggs remain in the ovaries.

Tests & investigations

Ovarian reserve is estimated with AMH and an antral follicle count, sometimes with early-cycle FSH. It helps predict how many eggs a stimulation cycle may produce and guides the dose of medication. It says very little about egg quality, which tracks mainly with age, and it is a poor predictor of natural conception on its own.

Also known as: egg reserve, egg count, how many eggs left
