Ovarian reserve
The number and quality of eggs remaining in the ovaries at a given time.
In plain English
It's a general term for how many eggs you have left and how well they're likely to respond to stimulation.
Why it matters
It naturally declines with age and is estimated using tests like AMH and antral follicle count, though no test predicts egg quality directly.
