Ovary volume in young and premenopausal adults: US determination. Work in progress

Normal adult ovary volume determined by ultrasonography (US) is often stated to be less than 6 cm3. This is based on data from teenagers and young adults aged 12-20 years. Recently, the mean normal volume determined by US was reported to be considerably higher. We measured the volumes of 28 ovaries from 15 healthy young adults and found them to range as high as 13.84 cm3, with an average of 6.48 cm3.
