Why It Is Done

Healthcare providers do not always use a transvaginal ultrasound during infertility evaluations, especially if the healthcare provider decides that a hysteroscopy or laparoscopy is necessary. However, transvaginal ultrasound is essential to monitor the growth and development of the follicles when the ovaries are stimulated with fertility drugs to induce ovulation.

An ultrasound can also be used to measure the thickness of the uterine lining to help determine if the lining is adequately prepared for an ensuing pregnancy.

How It Is Done

A full bladder is not needed for this type of ultrasound. A transducer is inserted into the vagina, which feels similar to inserting a tampon. The transducer relays images of the uterus, fallopian tubes and ovaries onto a computer screen.
