What does diminished ovarian reserve (DOR) mean?Updated 2 hours ago

It means a lower number of eggs than expected for your age. Fertility doctors routinely measure ovarian reserve because it helps them advise on treatment options and success rates.

DOR may be linked to earlier menopause, depending on your age. It can also mean a lower response to fertility medication, so fewer eggs retrieved per IVF cycle. That's useful for setting expectations, planning, and budgeting, since you may need more than one treatment cycle.

DOR is a clinical diagnosis made by your doctor, and elevated FSH is only one marker. This screening test can flag when further testing, like bloodwork and an ultrasound, is a good idea. It doesn't measure egg quality, and it doesn't predict whether you'll conceive without help.
