Transvaginal Ultrasound: Duration, Procedure, Preparation & Results

What is a Transvaginal Ultrasound?

A transvaginal ultrasound is an imaging test used to examine the pelvic organs, including the uterus and ovaries, from inside the vagina. Doctors recommend it when they need a clearer view of the pelvic area, especially in cases of pelvic pain, irregular periods, unusual bleeding or fertility concerns.

The scan uses sound waves to create detailed images. Because it is performed internally, it provides clearer results than an abdominal ultrasound, particularly during early pregnancy or fertility assessments. A thin, smooth probe is gently inserted into the vagina to capture these images and the procedure is usually quick and well tolerated.

This test helps doctors understand reproductive health concerns, identify possible causes of symptoms and decide on the next steps in care.

How Long Does a Transvaginal Ultrasound Take?

A transvaginal ultrasound usually takes 15-30 minutes from start to finish. The actual scanning time is often shorter, typically 10 to 15 minutes.

The total duration may vary depending on:

• The reason for the scan
• Whether it is part of fertility or cycle monitoring
• How easily the pelvic organs can be visualised
• Whether measurements or images need to be repeated

How is a Transvaginal Ultrasound Performed?

A transvaginal ultrasound is a routine and straightforward procedure. It is usually performed as follows:

• Before the scan, you will be asked to empty your bladder to help obtain clearer images.
• You will lie on an examination table, typically on your back with your knees bent.
• The ultrasound probe is slim, covered with a protective sheath and lubricated with a small amount of gel.
• The probe is gently inserted into the vagina to allow a close view of the pelvic organs.
• The sonographer slowly adjusts the probe to examine the uterus, ovaries and surrounding areas.
• You may be asked to change position slightly to improve visibility.
• Some pressure may be felt during the scan, but it should not be painful.

Does a Transvaginal Ultrasound Hurt?

For most people, a transvaginal ultrasound does not hurt. The scan may feel mildly uncomfortable, but it should not be painful.

Sensations can vary. Some people notice light pressure during the scan, while others feel very little. Discomfort may be more noticeable in certain situations, such as:

• Pelvic tenderness, inflammation or the presence of cysts
• Feeling tense or anxious at the time of the scan
• Frequent scans as part of fertility treatment or cycle tracking

If anything feels uncomfortable, it is important to say so. Small adjustments during the scan can help improve comfort.

How Should You Prepare for a Transvaginal Ultrasound?

Preparation for a transvaginal ultrasound is minimal. Before your appointment:

• Empty your bladder unless instructed otherwise
• Wear comfortable clothing
• Inform your provider if you are pregnant or suspect pregnancy
• Mention any pelvic pain or discomfort beforehand

How Are the Results Interpreted?

After the scan, the images are reviewed by a radiologist or your doctor. In some cases, the findings may be discussed immediately; in others, they are explained during a follow-up visit. While many people ask how long does a transvaginal ultrasound take, interpreting the results usually takes longer than performing the scan.

The images help doctors assess:

• The size and shape of the uterus
• The thickness of the endometrial lining
• The number and size of ovarian follicles
• The presence of cysts, fibroids or other structural changes

Is a Transvaginal Ultrasound Safe?

A transvaginal ultrasound is considered safe for most people. It does not use radiation and can be repeated if your doctor needs to monitor changes over time.

It is commonly used in early pregnancy, during fertility treatments and to examine the uterus, ovaries and other pelvic organs. You may feel mild pressure or slight discomfort during the scan, but serious complications are very rare.

When Should You Contact Your Doctor?

You should contact your doctor if you experience:

• Ongoing pelvic pain after the scan
• Heavy or persistent bleeding
• Worsening symptoms following the procedure

Conclusion

A transvaginal ultrasound is a commonly used test that helps doctors get a clear and detailed view of the uterus and ovaries when more information is needed. The scan itself is usually brief, preparation is simple and the procedure is routine in most clinical settings. Knowing how long does a transvaginal ultrasound take and what to expect during the scan can help reduce anxiety before the appointment.

Beyond the procedure, the real value of this test lies in the clarity it provides. Whether it is used for fertility monitoring, early pregnancy assessment or to investigate symptoms such as pelvic pain or abnormal bleeding, the results help guide important decisions about care. Understanding why the scan is done and what it can show allows you to have more informed conversations with your doctor and feel more confident about the next steps in your health journey.
