A Transvaginal Scan (TVS) is an ultrasound imaging technique that uses a small probe inserted into the vagina to create high-resolution images of a woman’s reproductive organs, including the uterus, ovaries, cervix, and fallopian tubes. It provides detailed insight into pelvic structures and helps detect various gynecological conditions. TVS is particularly advantageous over abdominal ultrasound because it offers a closer, more precise view of the pelvic anatomy without interference from abdominal tissues.
Routine TVS : This is a standard examination that provides a general view of the uterus and ovaries. Routine TVS is commonly used to evaluate symptoms like pelvic pain, abnormal bleeding, or to investigate infertility. It is also instrumental in assessing the condition of the uterus, checking for fibroids, cysts, endometriosis, or any structural abnormalities in the pelvic organs.
Antral Follicle Count (AFC) : This specialized type of TVS is used to assess ovarian reserve in women. The scan measures the number of antral follicles present in the ovaries, which correlates with a woman’s remaining egg supply. This count is crucial for women considering fertility treatments as it helps estimate their chances of successful conception, whether naturally or with assisted reproductive technology (ART) like IVF.
During a transvaginal scan, the patient is usually positioned with her knees bent, and the transducer, covered with a protective sheath and lubricated for comfort, is gently inserted into the vagina. The procedure is generally well-tolerated and completed within 15-20 minutes, with minimal discomfort.
