Meaning and Distinctions
What does diminished ovarian function mean?
Age, AMH, antral follicle count, FSH, and previous stimulation responses are interpreted together. Diminished ovarian function is a term used to describe the possibility that there are fewer follicles and eggs available to respond to ovarian stimulation compared to others in the same age group. It does not mean that egg quality or the possibility of natural pregnancy is determined by a single value.
- Easily confused terms
- It does not mean the same thing as premature ovarian failure or early menopause; people with regular menstruation can also be told they have diminished ovarian reserve.
- Why this is checked during medical evaluation
- Rather than spending time being frightened by test values, this information is used to determine the right time for infertility counseling based on your current age and pregnancy plans.
- What to record for your visit
- Do not compare the AMH value alone; please prepare the test date, the number of follicles seen on ultrasound, and the response to previous procedures.

- Condition GuideDiminished Ovarian ReserveDiminished ovarian reserve refers to a state where the number of remaining follicles is lower than expected or the ovarian response to stimulation is low, with natural decline due to age being the most significant factor. Genetic factors such as FMR1 premutation, ovarian surgery, chemotherapy, radiation, and certain systemic diseases can accelerate this decline, although in some cases, the cause remains unknown. A low AMH level alone cannot be used to determine egg quality or the impossibility of natural conception.→
- Condition GuideInfertilityInfertility is not a problem caused solely by women. In women, ovulation disorders, fallopian tube damage or blockage, endometriosis, uterine structural issues, and age-related changes in ovarian function may be involved. In men, sperm count, motility, morphology, varicocele, hormones, or ejaculation issues may be the cause. Since factors from both partners may overlap or the cause may not be clear from the initial evaluation, female examinations and semen analysis are planned together from the start.→
- Medical Evaluation GuideWhat should I prepare before a consultation for women's health conditions?Please record the start date and bleeding dates of your last three cycles, the number of times you changed products on your heaviest day, the location of pain, and your response to painkillers. Regarding discharge and itching, please prepare your test results and previous treatment responses rather than self-diagnosing the odor and color. Please also provide full details on the possibility or planning of pregnancy, ultrasound or blood tests, and any hormone medications, contraceptives, infertility treatment medications, or supplements.→
