The norm of the size of the ovaries in women according to ultrasound

The size of the ovaries in women can normally change throughout the menstrual cycle and throughout life. The sex gland in which the dominant follicle matures is always slightly larger than the other. With the onset of menopause, the activity of the ovaries decreases, and their size gradually becomes smaller.

What determines the size of the ovaries in women

Ultrasound diagnostics is used to determine the volume of the gonad. Preliminary preparation is not required, the patient can go to the study on any day of the cycle. Having determined the location of the ovary by ultrasound, the specialist takes measurements. To assess the condition of the pelvic organs, the doctor needs to know more information about the patient.

The size of the ovaries in women

Affect the size of the sex glands can:

  • day of the menstrual cycle;
  • the age of the patient;
  • tumor processes;
  • inflammatory diseases;
  • the number of births and pregnancies in history;
  • surgical interventions in the pelvic cavity;
  • taking hormonal contraceptives;
  • endocrine diseases.

Given the individual characteristics, the specialist determines whether the size of the gonad in this patient is normal.

Normal performance

The volume of the female gonad is a variable value, measured in cm or mm. Normal sizes are:

  • volume 4-10 cubic cm;
  • length 2-4 cm;
  • width 1.8-3 cm;
  • height 1.6-2.2 cm.

Immediately after menstruation, the size of the gonads reaches a minimum. After the completion of bleeding within 1-2 weeks, the maturation of the egg occurs. During this period, 10-15 follicles are determined, which increase the volume of the gland.

The right ovary ovulates more often. This is due to the peculiarities of the blood supply to the internal organs. From this side, functional cysts and tumors of a benign nature are more often diagnosed.

At ovulation, the diameter of the gonad reaches its maximum size. Usually one dominant follicle with a volume of 18-22 mm matures in the ovary, but sometimes there can be 2 or even 3. After the release of the egg, a corpus luteum appears, which does not greatly affect the size of the gonad. During pregnancy, it sometimes becomes larger, while doctors talk about a luteal cyst. If conception has not occurred, then with the approach of the next menstruation, the size of the gland decreases.

The size of the ovaries during inflammation

The inflammatory process in the ovaries is called oophoritis. This condition is determined by the clinical picture, laboratory tests and confirmed by ultrasound. The localization of the inflammatory process is often bilateral, but sometimes only an increase in the left ovary is established, or vice versa.

Enlargement of the ovaries with inflammation

When infected, the gonadal capsule stretches and increases in volume. This process may be accompanied by a lack of ovulation and dysfunction. It is impossible to name the exact dimensions of the ovary, characteristic of the inflammatory process. For each patient, they may differ, but, as a rule, exceed the permissible limits.

Ovarian size in women after menopause

In women, menopause occurs in the 60th year of life. It is preceded by menopause, in which the size of the gonads decreases. Follicular maturation and egg release occur episodically, and most cycles are anovulatory. Menstruation becomes irregular with long breaks. These processes are due to a decrease in the activity of the gonads and their gradual withering.

The normal size of the ovary in the postmenopausal period are:

  • volume from 1 to 4 cm3;
  • length 2-2.5 cm;
  • width 1.2-1.5 cm;
  • height 0.9-1.2 cm.

With the development of the inflammatory process, the organs also increase in size.

Women over 40 are more likely to experience tumors, so they need periodic monitoring of the condition of the pelvic organs. With the formation of cysts, the volume of the ovary can greatly increase.


After the ultrasound diagnosis, the patient is given a conclusion. It contains the data obtained and indicates the size of the ovaries . Usually, the sonologist indicates whether the gonad corresponds to the phase of the menstrual cycle and whether its follicular apparatus is preserved. Based on these findings, the gynecologist can make further recommendations.

You can try to do the decoding yourself, but only if the size of the ovaries is normal. With a reduced or enlarged gonad, one cannot do without consulting a gynecologist.


The size of the gonads in women can provide important information about the state of reproductive health. Normally, the volume of the ovaries should correspond to generally accepted standards. If a woman has a history of surgery to remove cysts, then the size will be reduced, which is also a natural consequence of the treatment.
