Diminished ovarian reserve

Understand what ovarian-reserve markers measure — and what they cannot predict.

Editorial publication · Medical review pending.

Understand

Diminished ovarian reserve describes an estimated lower oocyte quantity or reduced expected response to stimulation compared with age. It does not directly measure oocyte quality and is not the same as inability to become pregnant.

Possible symptoms

There are often no symptoms and periods may remain regular. It is commonly identified during fertility assessment or after a low response to stimulation.

Causes and associated factors

Age is the main factor. Ovarian surgery, some cancer treatments, genetic factors or an unknown cause can also contribute.

Diagnosis

Results are interpreted alongside age, reproductive history, medical history and any previous treatment response. One number cannot define an individual’s fertility.

Tests

AMH, antral follicle count and sometimes FSH and estradiol mainly help predict ovarian response to stimulation. They poorly predict spontaneous pregnancy and should not be used alone to deny treatment.

Course of the condition

Ovarian reserve falls over time, but the rate and possibility of conception vary. A low result cannot say exactly how much time remains before menopause.

Care options

Care clarifies goals and timing, addresses other factors and may tailor stimulation. No intervention creates new oocytes; claims of ovarian rejuvenation require particular caution.

When to consult

Seek specialist discussion after a low result, ovarian surgery or gonadotoxic treatment, or when timing is especially important to reproductive plans.

Urgent help

Low reserve is not an emergency. During treatment, significant pain, rapid abdominal swelling, shortness of breath, heavy bleeding or collapse needs urgent advice.

Questions for your doctor

  • Which cause or combination of factors explains our fertility difficulty?
  • Which tests are genuinely useful before deciding?
  • Which options exist before or instead of IVF?
  • Which benefits, limits, risks and costs should we compare?
  • What support and reassessment timeline should we plan?
