The left ovary 22×12 is the size of the ovary detected by ultrasound and is not necessarily related to whether the ovary is atrophied or not. If the ovary is atrophied, it depends on the function of the ovary, not on the size of the ovary. If there is no tumor on the ovary, then whether the ovary is atrophied should be judged by function. The hormone six items can be checked, and if abnormal hormone levels are found, such as decreased ovarian estrogen levels, increased follicle stimulating hormone, or accompanied by a significant decrease in menstrual flow, or even menopause, amenorrhea, or menopause, then ovarian atrophy is considered. Ovarian atrophy is not an imaging diagnosis, but a functional judgment, which is made based on clinical symptoms and hormone levels. If the patient shows decreased menstrual flow, prolonged menstrual cycle or even menopause, further examination of sex hormone six is required. Decreased ovarian function is considered when follicle stimulating hormone is significantly elevated. If the patient is older than 40 years old with menopause, it is a sign of obvious diminished ovarian function, and only then is atrophy of the ovaries considered.
