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.

We focus on egg access + quality protection—with protocols designed to avoid overstimulation, preserve the dominant follicle, and reduce cycle cancellations.
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.
We avoid pushing FSH to extremes that can interfere with follicle maturation (“overstimulation syndrome” in our clinical experience).
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.
When there are only 1–2 follicles, technique matters—follicle flushing may be used to reduce the chance of missing an egg.
DOR rarely improves, so we consider egg/embryo banking when it supports your family goals and timeline.
Patient Success Story - How Low Complexity IVF Can Help Women with Diminished Ovarian Reserve

Review your goals, timeline, and urgency (age, family size goals, time constraints)
Review ovarian reserve markers (AMH, FSH/E2, AFC) and cycle patterns
Analyze any prior IUI/IVF cycles (follicle recruitment, egg maturity, embryo development)
Screen for contributing factors (surgery history, endometriosis, autoimmune/thyroid patterns, genetics/family history)
Baseline ultrasound (AFC, ovarian appearance, cyst check)
Baseline labs (FSH/E2 ± LH, AMH review, thyroid/prolactin as indicated)
Identify whether this cycle is a “good start” cycle and what dosing/timing signals look like
Choose a plan designed for quality + timing efficiency, which may include:
Mini IVF (mild stimulation)
Natural-cycle IVF (when appropriate)
Lower-dose conventional IVF (personalized to avoid overstimulation)
Back-to-back mild cycles or embryo banking (when helpful for family-size goals)
Build a plan around your response pattern (not a standard calendar)
Set monitoring with decision points to avoid overstimulation or overmaturation
Confirm trigger strategy to optimize egg maturity and retrieval timing
Begin stimulation approach selected for your biology (often lower-med)
Ultrasounds/labs guide real-time adjustments to medication and timing
Focus on recruiting a small number of high-potential eggs safely
Trigger timed precisely to egg maturity
Egg retrieval (outpatient)
Fertilization via IVF/ICSI as indicated
Embryo development tracking (with blastocyst culture when appropriate)
Transfer planning (often FET timed to the best uterine environment)
If needed: embryo banking strategy across multiple cycles
Adjust the plan based on response and outcomes to improve efficiency and reduce wasted cycles

Your AMH is low, AFC is low, and/or FSH is elevated
You’ve been told your cycle may be canceled unless you produce “enough” follicles
You’ve had poor response to high-dose stimulation (or felt worse with higher meds)
You’re 35+ or you feel time-sensitive and want a clear strategy
You want a plan that balances immediate pregnancy goals with future family planning
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
You’re not ready for treatment yet and want a preservation-first strategy (we can plan proactively)

Type of IVF strategy recommended (gentle vs. conventional stimulation)
Monitoring needs (ultrasounds + labs)
Fertilization approach (ICSI may be recommended in DOR cases)
Embryo freezing/storage and whether banking is part of the plan
Any uterine or diagnostic procedures needed before transfer
Often included: physician oversight, retrieval procedure, standard lab steps (package-dependent)
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.
Age (a major driver of embryo chromosomal health)
Underlying infertility factors beyond DOR (uterine/tubal/sperm/timing)
Protocol choice (avoiding overstimulation and overmaturation)
Number of eggs retrieved across time (including banking strategy)
Transfer environment and timing (fresh vs. frozen strategy as indicated)

More monitoring precision when follicle numbers are low (timing matters)
Designed to support maturation without pushing you into an unhelpful “more is better” range
Outpatient procedure with a strategy suited to low follicle counts (including flushing when appropriate)
Fertilization planning (often ICSI), then transfer planning or banking plan depending on goals
It means your ovarian reserve markers (AMH, AFC, and/or FSH) suggest fewer eggs are available to recruit in a given cycle.
Not necessarily. DOR often affects how many eggs you can access, but pregnancy can still be possible—especially with a strategy designed for low reserve.
Not always. If you’re cycling regularly, there may be additional factors that need evaluation (uterine, tubal, sperm, timing).
Some clinics set minimum follicle thresholds and cancel cycles if too few follicles develop. That can limit opportunity for patients with low reserve.
Not always. Traditional approaches often increase medication, but this doesn’t work consistently—and pushing FSH too high may interfere with maturation in some cases.
We prioritize access without cancellation-by-default, avoid “overstimulation syndrome,” preserve the dominant follicle, and use retrieval techniques (like follicle flushing) when appropriate.
When egg numbers are limited, ICSI may help maximize fertilization opportunity as part of an efficiency-focused plan.
Sometimes. Because DOR rarely improves, banking embryos now can support future opportunities—especially if you’re planning more than one child.
