Ovarian reserve

The number of eggs remaining in the ovaries.

Testing

Ovarian reserve describes quantity, not quality. It is estimated with AMH and antral follicle count, both of which help predict the response to IVF stimulation. A low result at a young age does not mean natural pregnancy is impossible; a reassuring result at an older age does not undo age-related changes in egg quality.

Also known as: egg reserve, egg supply, diminished ovarian reserve, DOR
