A Transvaginal Scan (TVS) is a detailed ultrasound procedure used to examine the uterus, ovaries, fallopian tubes, cervix, and endometrial lining.
Unlike an abdominal ultrasound, where the probe is placed on the stomach, a TVS scan involves inserting a thin ultrasound probe into the vagina, providing high-resolution images of the pelvic organs.
TVS is commonly used for early pregnancy detection, diagnosing gynecological conditions, fertility monitoring, and assessing abnormal bleeding or pelvic pain. If your doctor has recommended a TVS scan, understanding what to expect can help ease any concerns.
Step-by-Step Overview of a TVS Scan Procedure
A TVS ultrasound is a quick and simple procedure, usually performed by a trained radiologist in a private and comfortable setting.
1. Preparation Before the Scan
You may be asked to empty your bladder before the scan for better imaging. You will also need to remove clothing for easy access to the scan area and lie on the examination table. A sheet or gown will be provided.
2. Probe Insertion and Imaging
The ultrasound probe (transducer) is covered with a sterile protective sheath and lubricating gel for smooth insertion. The radiologist gently inserts the probe into the vaginal canal.
The probe sends high-frequency sound waves to create images of the pelvic organs. The radiologist moves the probe slightly to capture different angles for a comprehensive view.
3. Image Capture and Evaluation
The images appear instantly on a monitor, allowing the radiologist to examine the uterus, ovaries, endometrial lining, and blood flow.
The scan typically takes 10–20 minutes, depending on the reason for the test. Once the imaging is complete, the probe is removed, and you can get dressed.
TVS scans are non-invasive, safe, and performed with great care to ensure patient comfort.

Does TVS Scan Hurt? Addressing Common Concerns
A Transvaginal scan is not painful, but some women may experience mild discomfort or pressure during the procedure.
Factors That May Affect Discomfort Level:
- Tight pelvic muscles: If you feel tense, it may cause slight discomfort. Deep breathing and relaxing help ease the process.
- Existing pelvic conditions: Women with ovarian cysts, endometriosis, or infections may feel a bit more pressure.
- Personal pain tolerance: Sensitivity levels vary from person to person.
What Can You Do to Reduce Discomfort?
- Try to relax and breathe deeply during the procedure.
- Inform the radiologist if you feel excessive discomfort, and they will adjust accordingly.
- Keep in mind that the procedure is quick and does not cause lasting pain.
Most women find the TVS scan to be a well-tolerated and routine procedure with minimal discomfort.
How Long Does a TVS Scan Take?
A TVS scan typically takes between 10 to 20 minutes.
Factors That May Affect Scan Duration:
- If multiple images are needed, the scan may take longer.
- A more detailed examination of ovarian follicles in fertility treatments may extend the scan.
- If there are abnormal findings, the radiologist may take additional images for clarity.
The entire appointment, including preparation and discussion, may last 30–40 minutes.
Since no recovery time is needed, you can resume normal activities immediately after the scan.

What Happens After the Scan? Understanding Your Results
Once the scan is completed, the radiologist will review the images and prepare a report for your doctor.
1. Receiving Your Results
Results are provided immediately, ensuring a quicker diagnosis and timely follow-ups. Your healthcare provider will review the findings, explain them in detail, and discuss any necessary next steps.
2. Normal vs. Abnormal Findings
A normal TVS scan confirms that the uterus, ovaries, and endometrial lining appear healthy. If abnormalities such as fibroids, cysts, PCOS, or early pregnancy complications are detected, further tests may be recommended.
3. Follow-Up Recommendations
If you are undergoing fertility treatment, your doctor may schedule additional scans to track ovulation or embryo implantation.
If the scan shows irregularities in the uterus or ovaries, further tests may be needed.
Your healthcare provider will guide you on the next steps based on the TVS scan results.
Why Regular Scans Are Key for Women’s Health Monitoring
A TVS scan is an essential tool for maintaining women’s reproductive health.
1. Early Detection of Gynecological Conditions
Identifies ovarian cysts, fibroids, and endometriosis before symptoms worsen. It helps detect PCOS, which affects ovulation and fertility.
2. Supports Fertility Treatments
Monitors ovulation and endometrial lining thickness for successful conception. Assesses embryo implantation in IVF treatments.
3. Ensures a Healthy Pregnancy
Confirms early pregnancy viability and fetal heartbeat. Identifies ectopic pregnancies, miscarriages, or placental abnormalities early.
Regular TVS scans help women detect reproductive issues early, ensuring timely medical intervention and better health outcomes.
