“…Furthermore, there was no significant difference (p ˃ 0.05) between disappearance of dominant follicle or reduction in size of a follicle as predictors of ovulation and laboratory analysis using LH test strips on subjects' serum. It was earlier reported in a similar study that where follicles either disappeared or were reduced in size, the patients all had positive serum LH tests (24). This result seems to suggest that sonographic folliculometry, like laboratory LH serum test, could be reliably used as a predictor of imminent ovulation.…”

“…El tamaño folicular en la fase de preovulación entre las sujetos osciló en el rangode [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36] mm, mientras que el tamaño folicular promedio fue 26.78 ± 4.03 mm. Antes de la ovulación, se observaron desaparición y reducción en el tamaño folicular en 59% y 41% de las sujetos, respectivamente.…”

Infertility is defined as the failure to conceive a desired pregnancy after 12 months of unprotected intercourse and affects approximately 10% of married couples. With recent technological development and proper use of medically assisted reproduction techniques, one half of these couples will become pregnant. More than any other new method, ultrasound has made significant improvements in the modern management of female infertility. Transvaginal sonography provides the reproductive endocrinologists with a tool that cannot only evaluate normal and stimulated cycles but also assist in follicle aspiration and subsequent transfer of the embryo. The addition of color Doppler capabilities to transvaginal probes permits visualization of small intraovarian and endometrial vessels, allowing depiction of normal and abnormal physiologic changes in the ovary and uterus. This article reviews on the assessment of ovarian, uterine and tubal causes of infertility and on the current and future role of color Doppler and three-dimensional ultrasound in the field of reproductive endocrinology.

Ultrasonographic morphology of the human preovulatory follicle wall prior to ovulation

Morphologic changes in the walls (stratumgranulosa andtheca interna andatema)of preovulatory follicles were studied in 15 clinically normal women. Ovulation was visualized in 11 of 15 (73%) women. Images were recorded using highresolution transvaginal ultrasonography. Mean follicular diameter immediately bcfort: ovulation was 20.7 It 0.6 mm. Echoes representing the cumulus oophorusl ooqte complex were observed in 10 of 11 (91%) follicles for which ovulation was ascertained. Thickness of the deep internal wall increased (P < 0.02) beginning from 4 to 5 h before ovulation. T h e apical wall thinned (P < 0.0001) to nondetectable limits immediately before follicular rupture. Four women (27%) did not ovulate during the imaging period 134-41 h post-human chorionic gonadotropin hCG]. T h e four follicles that did not ovulate remained of uniform thickness; stigma formation was not observed. T h e data supported the hypothesis that ultrasonographically detectable alterations in preovulatory follicles precede ovulation. Clinical applications include prediction of the potential for, and interval to, rupture of the preovulatory follicle and timing of ova retrieval in women undergoing ovarian stimulation for amelioration of infertility. 0 1992 Wiley-Liss, Inc.
