BACKGROUND: Endometriosis appears to have a multilayered etiology, with genetic and epigenetic factors each contributing half of the pathogenesis. The molecular processes that underlie the onset of endometriosis are yet unclear, but it is a…
BACKGROUND: The Live Birth Rate (LBR) after day 5 (D5) blastocyst transfer is significantly higher than that with D6 embryos in both fresh and frozen-vitrified embryo transfer cycles, according to the most recently published meta-analyses. …
STUDY QUESTION: Do severe endometriosis-related painful symptoms impact ART live birth rates? SUMMARY ANSWER: Severe pain symptoms are not associated with reduced ART live birth rates in endometriosis patients. WHAT IS KNOWN ALREADY: ART …
The oocyte transcriptome follows a tightly controlled dynamic that leads the oocyte to grow and mature. This succession of distinct transcriptional states determines embryonic development prior to embryonic genome activation. However, these…
OBJECTIVE: To investigate if there are any obvious clinical factors associated with delayed blastulation at day 6 (D6) compared with day 5 (D5). DESIGN: Monocentric observational cohort study from November 2012 to December 2018. SETTING: …
