The reason for a Transvaginal Ultrasound (TVS) scan is to visualize and assess the health of pelvic organs and reproductive structures in women. It aids in diagnosing gynecological conditions, monitoring pregnancies, evaluating fertility concerns, and providing detailed insights into reproductive health.

TVS is done in pregnancy to monitor fetal development, confirm pregnancy viability, assess gestational age, and detect potential issues such as ectopic pregnancies or early miscarriages. It offers detailed images of the uterus and ovaries, aiding in comprehensive prenatal care.

TVS scans are generally safe, but mild discomfort or spotting might occur due to the transvaginal probe insertion. In rare cases, there's a slight risk of infection or injury, but these instances are extremely uncommon.

It's typically recommended to have an empty bladder for a TVS scan, so avoid eating a large meal before the scan. However, you can usually have a light meal or snack if needed.

TVS (Transvaginal Ultrasound) is a specific type of ultrasound that involves inserting a probe into the vagina for closer imaging of pelvic organs. While both are ultrasound techniques, TVS is a more targeted approach for certain areas, like the reproductive system.
