Abdominal and vaginal sonographic monitoring were compared in 45 patients undergoing follicular development for the purposes of artificial insemination (N = 22) and in vitro fertilization (IVF; N = 23). Transvaginal sonography recorded a significantly ( p < 0.05) higher number of follicles from cycle day 10 on, compared to the abdominal (sector and linear) approach. Starting on day 8, the size of the dominant follicle was also significantly ( p < 0.05) higher when transvaginal endosongraphy was used. The number of follicles >15 mm on the day of human chorionic gonadotropin (hCG) administration was correlated with the number of oocytes retrieved in patients undergoing IVF. There was a significant linear correlation when transvaginal ( r = 0.86, p < 0.001) and sector ( r = 0.57, p < 0.05) scans were used.
