What is Diminished Ovarian Reserve?

Diminished ovarian reserve is a condition where the quantity and quality of a woman’s eggs are lower than expected for her age affecting 10-30% of women presenting with infertility. AMH below 1.0 ng/ml and FSH above 10 mIU/mL and antral follicle count below 5 on ultrasound indicate reduced reserve. Natural aging is the primary cause but surgery and endometriosis and genetics can accelerate the decline.

According to Dr. Hrishikesh Pai, renowned IVF Doctor in India, “Low ovarian reserve doesn’t mean zero chance of pregnancy but it does mean time is working against you and acting quickly makes a real difference.”

AMH under 1.0 ng/ml plus FSH over 10 mIU/mL plus fewer than 5 follicles and the diagnosis is confirmed.

• AMH Testing: Peaks in the mid-20s above 3.0 ng/ml then drops year by year. Under 1.0 ng/ml means diminished reserve. Undetectable levels show up about 5 years before menopause. Of all the markers AMH catches the decline earliest because it falls before FSH even starts rising
• FSH and Estradiol: Day 3 FSH above 10 mIU/mL is the first red flag. Above 15 mIU/mL and most clinics won’t even start fertility treatment stimulation because the ovaries won’t respond well enough. Estradiol over 80 pg/mL on day 3 backs up the same finding
• Antral Follicle Count: Normal is 8-11 per ovary on early follicular phase ultrasound. DOR patients show fewer than 5 total across both ovaries. Past 40 most women are down to fewer than 4 per side
• Fragile X Screening: Any woman with DOR under 40 needs Fragile X testing. It’s inherited and it’s linked to premature ovarian failure and it also happens to be the most common cause of inherited intellectual disability

No symptoms in most cases. Women find out when they try to conceive and it doesn’t happen. More about evaluation on the female infertility treatment page.

IVF with high-dose stimulation is the go-to. Under 37 the numbers still look reasonable. Past 40 with AMH that’s undetectable the math shifts toward donor eggs which sit at 51% pregnancy per cycle no matter how old the recipient is.

• IVF with High-Dose Stimulation: Bigger gonadotropin doses to pull out whatever eggs are left. Even 2-3 good ones can get the job done through IVF treatment if embryo selection and PGT-A testing are part of the plan
• Egg Freezing: Got a DOR diagnosis in your early 30s. Freeze now not later. Every month the reserve keeps dropping and eggs frozen today will always be chromosomally better than eggs retrieved two years from now. More about timing in this egg freezing guide
• Donor Eggs: AMH undetectable. Ovaries not responding to stimulation. That’s when donor eggs from younger women step in and restore pregnancy rates to 51% per IVF cycle regardless of the recipient’s own reserve status
• DHEA and CoQ10: 2-3 months of supplementation before IVF. DHEA addresses the androgen decline that comes with aging ovaries. CoQ10 supports mitochondrial energy production in the remaining eggs. Evidence is still building but most fertility clinics recommend both

No way to add eggs back once they’re gone but moving fast with whatever remains gives the best shot. How age plays into all of this is in this guide on getting pregnant with PCOS after 30.
