Sonographic monitoring of ovarian follicular development.
Serial sonographic examinations were performed on 15 volunteers five days during the expected midcycle. The 75 sonographic studies were evaluated in a nonbiased manner, and the following features were assessed: 1) the presence or absence of a follicle within the ovary; 2) if present, the average dimension of the follicle; 3) the ability to delineate both ovaries; and 4) the presence of associated changes, such as involution of the follicle, echogenic texture within the follicle, or fluid in the cul-de-sac. The sonographic findings were correlated with serial leutinizing hormone (LH) assays as well as basal body temperature charts. As defined in the study, the correlation between the sonographic findings and hormonal determination were considered excellent in 70% of the cases, good in 20%, and poor in 10%. Both ovaries were delineated in 73% of the examinations performed, thus substantiating the ability of sonography to detect maturing ovarian follicles.
