Research progress in ultrasound markers for endometrial receptivity assessment
Infertility is a worldwide reproductive health problem.Assisted reproductive technology has given numerous infertile women the chance to have their biological child.Despite the continuous development and maturation of clinical protocols and transfer techniques,more than a half of infertile women still fail to achieve a successful pregnancy with one cycle of embryo transfer.Endometrial receptivity is essential for pregnancy establishment and can be an important factor for pregnancy outcomes following in vitro fertilization and embryo transfer.Multiple modalities have been used to assess endometrial receptivity,the most commonly used in clinical practice is the convenient and non-invasive transvaginal ultrasound assessment.We reviewed ultrasound markers for endometrial receptivity assessment in terms of endometrial thickness,type,blood flow,peristaltic wave,volume and elasticity.
