Why This Test Is Done

Doctors may order this test to evaluate ovarian structure, diagnose conditions like ovarian cysts, or monitor reproductive health. It’s often part of a broader evaluation for infertility, hormonal imbalances, or pelvic pain.

What to Expect Before the Test

You’ll typically lie on your back with your feet in stirrups. A gel is applied to your abdomen or vagina to help the ultrasound probe glide smoothly. The test usually takes 15–30 minutes.

What Happens During the Test

The technician moves the probe over your abdomen or vagina to capture images of your ovaries. No needles or radiation are involved, and it’s generally painless.

What to Expect After the Test

You can resume normal activities immediately. Results are usually reviewed by your healthcare provider within a few days, who will discuss them with you.

Reference range

Adult males: 22-198 U/L; Females: 22-198 U/LN/A

Specimen: serum

No special preparation required. Inform provider of any chest pain or symptoms.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Ovarian thickness can indicate normal ovarian function, cysts, or other abnormalities. Abnormal measurements may signal conditions like PCOS, ovarian hyperstimulation, or ovarian reserve issues, guiding further treatment or monitoring.
