What is Low Ovarian Reserve?
💡 Low ovarian reserve (DOR) = fewer eggs than expected for age. Diagnosed: AMH <1.0 ng/mL, AFC <5–7, Day 3 FSH >10–12 IU/L. Causes: age, genetics, endometriosis, surgery, chemotherapy. Treatment: IVF with personalised high-dose protocol. Success rate lower but not zero — live birth possible even with AMH <0.1 ng/mL. Egg freezing recommended if diagnosed young.
Low ovarian reserve (diminished ovarian reserve / DOR) means a woman has fewer eggs remaining than expected for her age. It is diagnosed biochemically (low AMH, high Day 3 FSH) and structurally (low AFC on TVS). Low ovarian reserve reduces the chance of pregnancy per cycle — both naturally and with IVF — by limiting the number of eggs available for fertilisation.
🇮🇳 India Context: Low Ovarian Reserve is widely assessed and treated across major Indian fertility centres including Chennai, Mumbai, Bangalore, Delhi, and Hyderabad.
What are the key characteristics of Low Ovarian Reserve?
- Diagnostic criteria (POSEIDON/Bologna): AMH <1.2 ng/mL AND/OR AFC <5 AND/OR Day 3 FSH >10 IU/L; poor response in prior IVF cycle (<3–4 eggs with high dose); all criteria not required — one marker sufficient with clinical context
- POSEIDON classification: Group 1 (<35, unexpected poor response); Group 2 (≥35, unexpected poor response); Group 3 (<35, predicted poor response from baseline); Group 4 (≥35, predicted poor response) — guides tailored protocol selection
- Causes: physiological (age-related irreversible decline from ~35 years); premature (endometriosis, bilateral ovarian surgery, autoimmune POI, chemotherapy/radiotherapy, genetic — FMR1 premutation, Turner mosaic)
- Age vs reserve: low reserve is expected in women over 40; low reserve in a woman under 35 is premature and warrants investigation for cause
- Natural conception: possible with low AMH — egg quality in young women with DOR is usually preserved; the problem is quantity not quality in women under 35
- IVF with DOR: poor responder protocols — maximum dose FSH (300–450 IU/day); consider LH add-back (HMG or rLH); DHEA pre-treatment (75mg/day × 3 months); testosterone priming; dual stimulation (DuoStim); natural cycle IVF
- Cumulative success: multiple IVF cycles accumulate embryos; banking blastocysts across 2–3 cycles before transfer improves cumulative live birth rate in poor responders
- Egg donation threshold: when 2–3 own-egg IVF cycles yield no transferable embryos, donor egg IVF should be discussed — live birth rate 50–65% per transfer regardless of recipient age
How does Low Ovarian Reserve work?
Why does Low Ovarian Reserve matter in fertility?
Low ovarian reserve is the fertility diagnosis with the greatest time pressure — reserve declines irreversibly and the window for own-egg treatment narrows monthly. The most important clinical action for a young woman diagnosed with DOR is immediate fertility preservation counselling: egg or embryo freezing should be offered without delay. The most common management error is attempting repeated low-yield IVF cycles without escalating to donor eggs when own-egg cycles are clearly not producing viable embryos — each failed cycle costs time, money, and emotional reserves.

FAQs about Low Ovarian Reserve
What is a low AMH level for ovarian reserve?
AMH below 1.1 ng/mL at any age indicates diminished ovarian reserve. Below 0.5 ng/mL is considered very low. However, AMH predicts egg quantity, not egg quality — younger women with low AMH can still have good-quality eggs.
Can I get pregnant with low ovarian reserve?
Yes. Low ovarian reserve reduces the number of eggs available, but not necessarily their quality — especially in younger women. IVF with tailored high-dose stimulation, or donor egg IVF, achieves pregnancy in most cases.
What causes low ovarian reserve at a young age?
Causes in young women include genetic factors (FMR1 premutation, Turner mosaicism), autoimmune oophoritis, prior ovarian surgery, chemotherapy, radiotherapy, endometriosis, and — most commonly — no identifiable cause.
Does low AMH mean IVF will fail?
No. Low AMH predicts fewer eggs retrieved, not failed IVF. Women with low AMH may need higher medication doses, may get fewer embryos, and may need multiple cycles — but many achieve pregnancy, especially if younger than 38.
What supplements help low ovarian reserve?
DHEA (dehydroepiandrosterone) 75 mg/day for 3 months has some evidence for improving IVF response in DOR. CoQ10 supports egg mitochondrial function. Evidence is limited — always discuss with your specialist before starting.
