BACKGROUND: Implantation failure is the most common cause of pregnancy failure and is a major limiting factor in assisted reproduction. Plasma microRNA (miRNA) expression profiles show dynamic changes among individuals with successful impla…
STUDY QUESTION: What are the dynamic expression features of plasma microRNAs (miRNAs) during the peri-implantation period in women with successful pregnancy via single frozen-thawed blastocyst transfer? SUMMARY ANSWER: There is a significa…
Objective: To compare the cumulative live birth rates (cLBRs) after the first assisted reproductive technology (ART) cycle using flexible gonadotropin releasing hormone (GnRH)-antagonist protocol vs. standard long GnRH agonist protocol for …
Sperm morphology is the best predictor of fertilization potential, and the critical predictive information for supporting assisted reproductive methods selection. Given its important predictive value and the declining reality of semen quali…
