FOLLICULAR MONITORING: COMPARISON OF TRANSABDOMINAL AND TRANSVAGINAL SONOGRAPHY.

Transabdominal sonography (TAS) and Transvaginal sonography (TVS) were compared for follicular monitoring in 73 patients of infertility. These patients were referred for follicular monitoring in normal and stimulated cycles from infertility clinic. Patient compliance and acceptance was excellent for TVS technique as compared to TAS technique. The overall resolution of ovarian and follicular anatomy was much better in TVS. With TAS only 35.6% had good visualisation of follicles as compared to 80.8% (p<0.05) in TVS. TVS offered advantage of much better detection rate of smaller follicles (<10mm) and higher accuracy in assessing number of follicles.
