Transvaginal Ultrasound: A Detailed Guide for Pregnant Women

What is a Transvaginal Ultrasound?

A transvaginal ultrasound (TVS) is a diagnostic imaging procedure that uses high-frequency sound waves to create detailed images of the female reproductive organs. Unlike an abdominal ultrasound, where the probe is moved over the belly, this test involves inserting a small probe into the vagina for clearer imaging of the uterus, ovaries, fallopian tubes, and cervix.

Why is a Transvaginal Ultrasound Done?

A transvaginal ultrasound is commonly used for:

Early pregnancy monitoring (confirming pregnancy, detecting fetal heartbeat, and checking for ectopic pregnancy).
Assessing gynecological conditions such as fibroids, ovarian cysts, polycystic ovary syndrome (PCOS), endometriosis, or pelvic infections.
Evaluating unexplained pelvic pain or abnormal bleeding.
Monitoring fertility treatments and ovulation cycles.
Checking the thickness of the uterine lining in women undergoing hormone therapy or IVF.

How to Prepare for this Test?

Preparation for a TVS scan is simple:

You may be asked to empty your bladder before the procedure.
Wear comfortable clothing for easy access.
Inform the technician if you are pregnant or have any vaginal sensitivities.
The procedure is generally painless but may cause mild discomfort.

What Happens During the Procedure?

You will be asked to lie down with your knees bent and feet in stirrups.
A lubricated, covered ultrasound probe (transducer) will be gently inserted into the vagina.
The probe emits sound waves that create images on a screen, allowing the doctor to examine your reproductive organs.
The test usually takes about 15 to 30 minutes.

Are There Any Risks or Side Effects?

A endovaginal ultrasound. is a safe and non-invasive procedure with no radiation exposure. Some women may experience mild discomfort, but no known risks are associated with this test. If you experience pain or prolonged spotting afterward, consult your doctor.
