title: [Uterine factors limiting ART coverage].
abstract: Transvaginal sonographic evaluation of endometrial texture and thickness may be an indicator of the likelihood of achieving pregnancy. Very few pregnancies occur when the endometrial thickness was less than 6 mm. When type C endometrium (multilayered endometrium consisting of prominent outer and midline hyperechogenic lines and inner hypoechogenic regions) greater than or equal to 6 mm thick was seen, the pregnancy rate per embryo transfer is goods. MR imaging is highly accurate in helping to diagnose adenomyosis which is a cause of repeated implantation failures in women undergoing IVF. Furthermore the MRI evaluation of junctional zone thickness (AJZ>7 mm and MJZ>10 mm) is the best negative predictive factor of implantation failure (97%). Thus, we advocate the measurement of junctional zone thickness with MRI in women with 2 consecutive implantation failure following IVF.
