Ultrasound is generally only used as an adjunctive test for premature ovarian failure, and cannot diagnose premature ovarian failure on the basis of ultrasound alone. The diagnosis of premature ovarian failure depends on the examination of sex hormone levels combined with the corresponding symptoms and signs.
Premature ovarian failure is suspected in women under 40 years of age who have scanty menstruation, short periods, low menstrual flow or even amenorrhea that lasts for more than 6 months, accompanied by symptoms of low estrogen levels, such as hot flashes, excessive sweating, facial flushing, and low libido. Some patients may also have autoimmune diseases such as diabetes, lupus erythematosus, and rheumatoid arthritis.
The most important part of the diagnosis of premature ovarian failure is the measurement of sex hormone levels. If the results show that the blood follicle stimulating hormone level is consistently above 40 IU/L and the estradiol is below 50 to 90 pmol/L, combined with the above symptoms, and after other diseases are excluded, then the diagnosis of premature ovarian failure can be made.
In some patients with premature ovarian failure, due to ovarian decline and low estrogen levels, ultrasound examination may reveal ovarian atrophy, reduced uterine size, and the absence or presence of only a few follicles in the ovaries. When these signs appear, premature ovarian failure is suspected. If the ultrasound results are normal, it does not mean that the disease is not present and further examination is needed.
If there is any discomfort, it is recommended to go to the hospital in time to avoid delaying the condition.
