If your doctor has recommended one, here’s what you need to know.
What Is a Transvaginal Ultrasound?
Unlike a traditional abdominal ultrasound (where a probe is moved across your belly), a transvaginal ultrasound involves gently inserting a thin ultrasound probe into the vagina. This closer approach allows for clearer and more detailed images, especially for structures that are deeper in the pelvis.
The word “transvaginal” simply means “through the vagina.” The procedure is typically performed by our trained sonographer, and takes around 15 to 30 minutes.

Assessing the Uterine Lining
The endometrial thickness is important to evaluate in:
- Women undergoing fertility treatment
- Women with postmenopausal bleeding
- Possible endometrial hyperplasia or cancer
Early Pregnancy Assessment
It is especially useful in the first trimester to:
- Confirm a pregnancy and check for heartbeat
- Estimate gestational age
- Detect an ectopic pregnancy (outside the uterus)
- Investigate possible miscarriage
Infertility Evaluation
It may be used to:
- Monitor ovulation
- Assess the condition of the uterus and ovaries
- Guide fertility treatments like egg retrieval
Monitoring Intrauterine Devices (IUDs)
Helps verify the correct position of an IUD and check for complications.
What to Expect During the Procedure
- You will lie on your back with your knees bent, similar to a pelvic exam.
- A thin ultrasound probe, covered with a sterile cover and lubricated, is gently inserted into the vagina.
- You may feel some pressure, but it should not be painful.
- The probe sends sound waves that create images of the pelvic organs on a screen in real time.
Most women tolerate the exam well, and you can return to normal activities right afterward.
Is It Safe?
Yes—transvaginal ultrasound is very safe. It uses sound waves, not radiation, and there are no known risks. It can be safely used in early pregnancy and multiple times if needed.
When Should I Schedule It?
Transvaginal ultrasound can be done at any time, but in some cases, your doctor might recommend timing it during certain parts of your menstrual cycle (e.g., mid-cycle for ovulation tracking).
If you’re menstruating during the time of your appointment, let your provider know—depending on the reason for the scan, it may or may not affect the timing.
Can i use Medisave to pay for my ultrasound?
Yes, there may be some diagnoses like fibroids of abnormal menstrual bleeding that makes you eligible to use your medisave to pay for your Ultrasound. Do let our doctors know during your consultation that you are keen for this option and they will help you to assess your suitability for this.
