Polycystic ovary syndrome (PCOS) affects relative embryo morphokinetics observed by time-lapse imaging: an observational study.
Archives of gynecology and obstetrics ·doi:10.1007/s00404-026-08335-0

PurposeTo characterise the effect of polycystic ovary syndrome (PCOS) on embryo morphokinetics via time-lapse imaging, including absolute time points, relative time intervals, and ratios representing cleavage synchronicity.MethodsThis singl…

High multiple pregnancy rates after double embryo transfers in human: a retrospective cohort study.
Reproduction & fertility ·doi:10.1530/raf-24-0078

AbstractTo improve clinical outcomes of human medically assisted reproduction, the transfer of multiple embryos is frequently performed. This leads to high rates of multiple pregnancies. In this study we explored if a cohort of patients can…

P-522 Impact of TGFß/BMP/SMAD Pathway on Premature Ovarian Insuffiency (POI)
·doi:10.1093/humrep/deae108.862

Abstract Study question Is TGFß/BMP/SMAD pathway altered in women with POI and can results be detected from peripheral blood samples? Summary answer The TGFß/BMP/SMAD pathway mRNA-expression-alterations are detectable in leukocytes of women…

Patient- and cycle-specific factors affecting the outcome of frozen-thawed embryo transfers
Archives of gynecology and obstetrics ·doi:10.1007/s00404-023-07019-3

PURPOSE: This study attempted at identifying the main parameters influencing the outcome of frozen embryo transfers. METHODS: This is a single-center retrospective cohort study of 830 frozen-embryo-transfer cycles performed at a German uni…

Non-invasive Embryo Assessment: Altered Individual Protein Profile in Spent Culture Media from Embryos Transferred at Day 5
Reproductive sciences (Thousand Oaks, Calif.) ·doi:10.1007/s43032-020-00362-9

In order to improve ART outcome, non-invasive embryo assessment is gaining more and more attention. Therefore, the aim of this study is to determine the consecutive implantation potential via the secretome between blastocysts with or withou…

Intraindividual Embryo Morphokinetics Are Not Affected by a Switch of the Ovarian Stimulation Protocol Between GnRH Agonist vs. Antagonist Regimens in Consecutive Cycles.
Frontiers in endocrinology ·doi:10.3389/fendo.2020.00246

Background: The impact of controlled ovarian stimulation (COS) during medically assisted reproduction (MAR) on human embryogenesis is still unclear. Therefore, we investigated if early embryonic development is affected by the type of gonado…

Relative Morphokinetics Assessed by Time-Lapse Imaging Are Altered in Embryos From Patients With Endometriosis
Reproductive sciences (Thousand Oaks, Calif.) ·doi:10.1177/1933719117741373

IntroductionTime-lapse technology allows almost continuous noninvasive assessment of embryonic development. It was shown previously that relative kinetics defining cleavage synchronicity are better predictors of blastocyst quality than abso…
