The transducer is only about one inch in diameter, and just the first two or three inches, covered with a sterile sheath, are inserted into the vagina. As a result, it is more comfortable and less time-consuming than having an abdominal ultrasound scan. One special benefit of this new transducer is for women with infertility problems who are interested in Assisted Reproductive Programs. Before the vaginal transducer was available, many women were not accepted in these programs because their ovaries could not be adequately monitored using abdominal scanning. With the vaginal transducer, the doctor can more closely evaluate their ovaries, making many more women eligible for Assisted Reproductive programs.
Doctors use the vaginal transducer for many other types of examinations as well.
