The ultrasound of polycystic ovaries shows that there are ≥12 follicles in one or both ovaries, the follicles are small, usually 2-9mm in diameter, and the volume of the ovaries is usually greater than or equal to 10mL. polycystic ovaries is an unstandardized term that should be used to describe polycystic ovarian changes. polycystic ovarian changes and polycystic ovarian syndrome are different concepts and should not be confused. Polycystic ovary syndrome is a condition in which the patient has polycystic ovarian changes, accompanied by menstrual disorders. The patient is usually obese and hairy, and the menstrual disorders cause non-ovulation or sporadic ovulation, which can easily lead to infertility in the reproductive age. If the patient only has polycystic ovarian changes and no menstrual disorders, she can ovulate normally and should not be overly anxious.
