Question 1

Diminished ovarian reserve means the ovaries contain fewer eggs, and often eggs of reduced quality, compared with what is expected for a woman's age. It reflects a reduced response to the natural or medication-driven signals that recruit eggs each month. DOR is distinct from menopause and from premature ovarian insufficiency (when the ovaries stop working before age 40) — a woman with DOR still ovulates and menstruates but has a smaller remaining egg supply.

There is no single universally agreed definition. The most widely used research frameworks are the Bologna criteria (any two of: age ≥40, an abnormal ovarian reserve test, or a prior poor response to stimulation) and the POSEIDON criteria, which combine age with ovarian reserve test results to predict how many eggs can be retrieved.

Question 2

Diminished ovarian reserve is common among women seeking fertility care. It is found in roughly a quarter of patients presenting to IVF centers in the United States, and estimates suggest it affects about 10% of women with infertility overall Because egg supply falls naturally with age, the likelihood rises steadily as a woman gets older.

Question 3

The most important and universal factor is age — the pool of eggs declines progressively over a woman's reproductive life, and both the number and quality of eggs deteriorate, especially after the mid-30s. Beyond normal aging ("physiologic" DOR), a number of factors can accelerate the decline ("pathologic" DOR):

Prior ovarian surgery (for example, removal of ovarian cysts or endometriomas)
Chemotherapy or pelvic radiation
Family history of early or premature menopause
Genetic factors, most notably a fragile X (FMR1) premutation

Autoimmune conditions endometriosis, smoking, and environmental exposures to endocrine-disrupting chemicals

Question 4

DOR itself usually causes no symptoms. Most women have regular menstrual cycles and feel entirely well; it is most often discovered during a fertility evaluation or when planning to preserve fertility. Some women may notice cycles becoming shorter or slightly irregular over time. Because it is typically silent, testing is the only reliable way to detect it.

Question 5

DOR is assessed with a combination of blood tests and ultrasound, ideally interpreted together with the woman's age:

Anti-Müllerian hormone (AMH): A blood test produced by small growing follicles that reflects the size of the remaining egg pool. It can be drawn on any day of the cycle. Lower values suggest lower reserve (thresholds vary by laboratory; values below roughly 1 ng/mL are commonly cited as low).
Antral follicle count (AFC): A transvaginal ultrasound counting the small follicles in both ovaries. A count under about 5–7 suggests diminished reserve.
Day 2–4 FSH and Estradiol: Blood tests early in the cycle. A high FSH (for example, above 10–15 IU/L) indicates the pituitary is working harder to stimulate the ovaries.
7+ Days Post Ovulation Progesterone: Levels confirm that ovulation occurred and that the corpus luteum is secreting ample progesterone for the two-week implantation window.

It is important to understand what these tests can and cannot tell you: they estimate the quantity of eggs and the likely response to fertility medication, but they do not measure egg quality and do not, on their own, predict whether a woman can conceive naturally.

Question 6

There is no treatment that restores the number of eggs in the ovaries. The goal of care is to make the best use of the eggs that remain and to avoid delay, since reserve continues to decline over time. Options include:

Trying to conceive without delay, with prompt referral if pregnancy does not occur, because time is a critical factor.
In vitro fertilization (IVF), often recommended earlier in women with DOR because progression is unpredictable. The stimulation protocol is individualized. For younger women with low reserve, higher-response protocols (such as GnRH-agonist or "dual stimulation") may retrieve more eggs, whereas for older women with DOR high-dose stimulation offers little added benefit over milder approaches, and low-dose or letrozole-based protocols may be equally effective with less cost and burden.
Adjuvant therapies: A systematic review found that testosterone (androgen) supplementation before IVF was associated with higher live birth rates, and that testosterone, DHEA, and a "delayed-start" protocol increased the number of eggs retrieved; other add-ons showed no clear benefit.
Donor eggs, which offer the highest success rates when a woman's own egg quantity or quality is very low, particularly at older ages.
Fertility preservation (egg or embryo freezing) for women who wish to delay childbearing.

Question 7

The single most important factor is age, not the test numbers alone. Young women with DOR can still have good outcomes, especially with more than one treatment cycle: cumulative live birth rates reach roughly 45–60% in women under 40 (and higher under 35) after multiple IVF cycles, whereas for women aged 40 and older cumulative rates are much lower and gain little beyond about four cycles. A low AMH or AFC in a young woman is more encouraging than the same values in an older woman, because egg quality is generally better at younger ages.

Question 8

In Traditional Chinese Medicine (TCM), diminished ovarian reserve is understood primarily as a Kidney deficiency pattern. The Kidney organ system in Chinese Medicine is considered the foundation of reproduction, growth, and aging — it is said to store the "essence" (Jing) that governs fertility and the reproductive lifespan — so a decline in ovarian reserve is seen as a depletion of Kidney essence. This is frequently combined with secondary patterns such as Blood deficiency, Blood stasis (impaired pelvic and ovarian circulation), and Liver Qi stagnation (often linked to stress). The therapeutic principle is to "tonify the Kidney and nourish the blood," commonly expressed in formula names beginning with Bushen (tonify the Kidney) and Huoxue (invigorate the blood).

Common TCM approaches studied for DOR include:

Chinese herbal formulas to support ovarian function.
Acupuncture, Transcutaneous Electrical Acupoint Stimulation (TEAS) and moxibustion, with treatment principles of nourishing the kidney, strengthening the spleen, regulating liver qi, and promoting blood circulation.

What does the evidence show? Several systematic reviews and small trials report that acupuncture and herbal formulas may lower FSH, improve the FSH/LH ratio, and modestly raise AMH and antral follicle count, and laboratory studies suggest effects on ovarian blood flow, oxidative stress, and follicle survival.

Question 9

Prompt referral to a reproductive endocrinologist is appropriate for any woman who has been told she may have low ovarian reserve, as well as for those trying to conceive who are 35 or older after 6 months, or under 35 after 12 months, of unprotected intercourse. Because ovarian reserve declines with time and its progression is unpredictable, earlier evaluation is generally better — waiting rarely improves the outcome.
