Research advances in ultrasound evaluation index of endometrial receptivity in prediction of pregnancy outcome with assisted reproductive technology

Infertility has become a major problem in human health, while assisted reproductive technology is an important technology for treatment of infertility. Endometrial receptivity is one of the important factors affecting the outcome of in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI). This paper reviews the research advances in predicting pregnancy outcome in assisted reproductive technology using ultrasound evaluation index of endometrial receptivity.
