During the egg freezing process, it is routine to get a transvaginal ultrasound during initial consultations and monitoring appointments. Understanding what to expect during this type of ultrasound can help it make a smoother and more comfortable process for you.

What is a transvaginal ultrasound?

A transvaginal ultrasound (TVUS) is a safe, common imaging procedure that uses sound waves to create pictures of organs inside your pelvis, including the uterus, ovaries, and part of the cervix. Unlike an abdominal ultrasound, TVUS uses a small, thin probe (called a transducer or wand) that is gently placed inside the vagina. TVUS allows for clearer, more detailed images.

Why do I need a TVUS?

Your doctor may order this test to help evaluate different conditions or guide them during certain procedures:

Abnormal bleeding or pelvic pain
Ovarian cysts or fibroids
Infertility
Ovarian response to fertility medications
Early pregnancy location - intrauterine or ectopic
Placement of an IUD
Egg retrievals

What to expect

Before: No special preparation is usually needed, but you are often asked to empty your bladder to improve visualization.
During: You will lie on your back with your knees bent or legs in stirrups (similar to a pelvic exam). The probe is covered with a protective sheath and a small amount of gel for comfort. It is gently inserted into the vagina. You may feel mild pressure, but the test should not be painful with the exception of an ectopic pregnancy, fibroids, or endometriosis. The exam usually takes about 15–20 minutes based on the reason.
After: There is no recovery time needed, and you can return to normal activities right away, including sexual activity.

Is it safe?

Yes. TVUS uses sound waves — not radiation — so it is considered very safe, including during pregnancy.

Tips for comfort

Let the technician know if you feel any discomfort — the probe can be repositioned.
Taking slow, deep breaths can help you relax during the exam.
Feel free to ask questions at any time.

If you have concerns or questions about your results, your doctor will review them with you.

Overall, a transvaginal ultrasound is a safe, quick, and routine part of many types of reproductive and fertility care. Knowing what to expect can help you feel more comfortable and prepared for the exam. If you have questions about why a TVUS is recommended or what your results mean, your doctor can walk you through the findings and next steps.
