To establish reference values for the cervical length (CL) measurement by transvaginal ultrasound between 20 and 24+6 weeks of gestation in a large Brazilian population. A retrospective cross-sectional study was performed with 996 singleton pregnancies. The CL measurement (mm) using the transvaginal ultrasound was obtained in a sagittal view and the calipers positioned to measure the linear dis...

Objective – To assess the precision of individual ovarian volume measurements by 2D and 3D transvaginal ultrasound scan. Study Design – Transvaginal 2D and 3D ultrasound examinations were performed on 49 women attending a tertiary centre for investigation or treatment for subfertility. Two observers calculated ovarian volume, using both the prolate ellipsoid formula and virtual organ computer-a...

Examinations of the cervical mucus for determining its quantity and physical characteristics are used to provide a clinical marker for the timing of ovulation. We propose that transvaginal ultrasound, which is routinely used as a tool for monitoring follicular growth in patients undergoing ovulation induction, might also be used simultaneously for estimating cervical mucus measurements. With no...
