Diminished Ovarian Reserve (DOR)

Diminished Ovarian Reserve (DOR) means your ovarian reserve markers suggest fewer recruitable eggs than expected.

Often seen as a low antral follicle count (AFC), low AMH, and/or elevated FSH. DOR can feel like an urgent, discouraging diagnosis, but it does not automatically mean pregnancy is out of reach. At Hanabusa, DOR care starts with two priorities: (1) confirm what DOR does—and does not—explain, and (2) build a plan that improves access to eggs without compromising quality.

What is DOR?

A fertility condition where ovarian reserve markers (AFC, AMH, and/or FSH) indicate fewer eggs are available for recruitment in a given cycle.

The Hanabusa Difference

 With DOR, “more meds” isn’t always the answer.

We focus on egg access + quality protection—with protocols designed to avoid overstimulation, preserve the dominant follicle, and reduce cycle cancellations.

Pricing available icon
We look beyond the label

If you’re cycling regularly, DOR may not be the only reason you’re not conceiving—so we evaluate the full picture, not just the numbers.

Pricing available icon
Quality-first stimulation (not superstimulation)

We avoid pushing FSH to extremes that can interfere with follicle maturation (“overstimulation syndrome” in our clinical experience).

Pricing available icon
Preserving the dominant follicle

We don’t default to “sacrificing” the lead follicle to chase a larger cohort—because in DOR, that lead follicle may be your best opportunity.

Pricing available icon
Retrieval strategy built for low follicle counts

When there are only 1–2 follicles, technique matters—follicle flushing may be used to reduce the chance of missing an egg.

Plan for now + later

DOR rarely improves, so we consider egg/embryo banking when it supports your family goals and timeline.

Severe Diminished Ovarian Reserve (DOR)

Patient Success Story - How Low Complexity IVF Can Help Women with Diminished Ovarian Reserve

Your DOR Treatment Journey

DOR care should be structured, efficient, and individualized—so you get clarity quickly and avoid wasted cycles.

Step 1 - Consult + records review
Step 2 - Confirm the diagnosis + baseline testing
Step 3 - Strategy selection (best-fit pathway for DOR)
Step 4 - Personalized protocol design
Step 5 - Treatment cycle + monitoring
Step 6 - Retrieval + fertilization + embryo development
Step 7 - Next steps + ongoing plan

Many clinics use traditional IVF logic—maximize egg numbers—and may cancel cycles if follicle counts are “too low.” With DOR, that approach can reduce your opportunities. Our philosophy is different: protect quality, preserve your best follicle, and build a plan that keeps you moving forward.

You may be a fit for DOR-focused care if

Pricing available icon

Your AMH is low, AFC is low, and/or FSH is elevated

Pricing available icon

You’ve been told your cycle may be canceled unless you produce “enough” follicles

Pricing available icon

You’ve had poor response to high-dose stimulation (or felt worse with higher meds)

Pricing available icon

You’re 35+ or you feel time-sensitive and want a clear strategy

Pricing available icon

You want a plan that balances immediate pregnancy goals with future family planning

You may prefer another path if

Pricing available icon

Your reserve markers are reassuring and your primary issue appears to be elsewhere (tubal, uterine, male factor, timing)—we’ll guide you to the most direct fix

Pricing available icon

You’re not ready for treatment yet and want a preservation-first strategy (we can plan proactively)

What influences cost

Pricing available icon

Type of IVF strategy recommended (gentle vs. conventional stimulation)

Pricing available icon

Monitoring needs (ultrasounds + labs)

Pricing available icon

Fertilization approach (ICSI may be recommended in DOR cases)

Pricing available icon

Embryo freezing/storage and whether banking is part of the plan

Pricing available icon

Any uterine or diagnostic procedures needed before transfer

Typically included vs. not included:

Pricing available icon

Often included:  physician oversight, retrieval procedure, standard lab steps (package-dependent)

Pricing available icon

Often separate: medications, some monitoring, ICSI, PGT, freezing/storage, FET cycle

DOR affects access to eggs, not automatically egg quality—especially at younger ages. Success depends on creating the right opportunities and using a strategy that avoids cancellation and protects follicle maturation.

What impacts outcomes

Pricing available icon

Age (a major driver of embryo chromosomal health)

Pricing available icon

Underlying infertility factors beyond DOR (uterine/tubal/sperm/timing)

Pricing available icon

Protocol choice (avoiding overstimulation and overmaturation)

Pricing available icon

Number of eggs retrieved across time (including banking strategy)

Pricing available icon

Transfer environment and timing (fresh vs. frozen strategy as indicated)

Pricing available icon
Appointments

More monitoring precision when follicle numbers are low (timing matters)

Pricing available icon
Medication plan

Designed to support maturation without pushing you into an unhelpful “more is better” range

Pricing available icon
Retrieval day

Outpatient procedure with a strategy suited to low follicle counts (including flushing when appropriate)

Pricing available icon
Next steps

Fertilization planning (often ICSI), then transfer planning or banking plan depending on goals
