A transvaginal ultrasound (TVS) is a commonly performed imaging test that helps doctors get a clearer view of the uterus, ovaries and other pelvic organs. Although some women may feel anxious or uncomfortable when they hear about a TVS scan, understanding how it works and why it is recommended can help ease these concerns.
What Is a Transvaginal Ultrasound?
A transvaginal ultrasound, also known as a TVS scan or transvaginal sonography, is an ultrasound examination performed by gently inserting an ultrasound probe into the vagina.
The scan provides a clearer and more detailed view of the uterus, ovaries and other pelvic organs compared with a transabdominal ultrasound in certain situations. This is why your doctor may recommend a TVS scan as part of your evaluation.
Why Is a TVS Scan Done?
A transvaginal ultrasound has several applications in gynecology, fertility care and early pregnancy evaluation.
Your doctor may recommend a TVS scan for:
1. Infertility Evaluation
TVS can help assess the anatomy of the uterus and ovaries. It can also help doctors examine ovarian follicles during follicular monitoring.
2. Heavy or Abnormal Menstrual Bleeding
A TVS scan can help evaluate possible causes of heavy menstrual bleeding and, when indicated, post-menopausal bleeding.
3. Fibroids and Ovarian Cysts
The scan can help identify conditions such as uterine fibroids and ovarian cysts.
4. Early Pregnancy
A transvaginal ultrasound can provide an early view of the pregnancy, including the developing baby and heartbeat, particularly in the early weeks of pregnancy.
5. Ectopic Pregnancy
TVS can also be used when doctors need to evaluate for an ectopic pregnancy.
6. Cervix and Placenta Evaluation
Later in pregnancy, a transvaginal scan may be recommended to assess the cervix or examine the location of the placenta when clinically required.
Is a Transvaginal Ultrasound Painful?
One of the most common concerns about TVS is whether it will be painful.
A transvaginal ultrasound is usually not painful, although some women may experience a certain amount of discomfort during the examination. Staying relaxed and taking deep breaths can help relax the pelvic muscles and reduce discomfort.
Anxiety and fear can sometimes make the experience feel more uncomfortable, so communicating with your healthcare professional during the examination is important.
Can You Have a TVS Scan During Your Period?
Yes. A TVS scan can be performed during menstruation when medically indicated.
In fact, if your doctor is evaluating the causes of heavy menstrual bleeding, a transvaginal ultrasound may be recommended even when you are having your period.
Does a TVS Scan Increase the Risk of Miscarriage?
A common concern is that a transvaginal ultrasound could cause miscarriage or harm the pelvic organs.
According to the doctor in the video, a TVS scan does not increase the risk of miscarriage. The ultrasound probe is used to obtain images and does not touch the baby or internal pelvic organs in the way many patients fear.
If you are pregnant and have concerns about the safety of the scan, discuss them with your doctor before the examination.
Is a TVS Scan a Reason to Panic?
No. Being advised to undergo a transvaginal ultrasound does not necessarily mean that something is seriously wrong.
TVS is a commonly used ultrasound examination that helps your gynecologist assess the pelvic organs in greater detail and complete the evaluation.
When May a TVS Scan Not Be Recommended?
The doctor explains that a TVS scan may not be advisable for women who are not sexually active, as the procedure may cause discomfort or bleeding. Your doctor can recommend an appropriate alternative based on your individual situation.
