Sonographic evaluation of the cervix during ovulation induction.

With the induction of ovulation, clomiphene citrate and human menopausal gonadotropin have the potential to stimulate the endocervical glands. We have found that the degree of mucus production can occasionally be quite large and hence is detectable by sonographic evaluation as an anechoic cervical mass. The incidence of this specific ultrasonic finding was found to be approximately 5%. This physiologic process should be differentiated from disease states affecting the cervix.
