New Technologies to Improve Embryo Assessment

Fertility & Reproduction, 2023
Embryo quality is a key factor in determining whether an IVF cycle will result in a live birth. Current approaches for assessing embryo quality are subjective (morphology) or invasive (biopsy) and are not always predictive of live birth.

Measuring embryo metabolism to predict embryo quality [PDF]

Reproduction, Fertility and Development, 2015
Measuring the metabolism of early embryos has the potential to be used as a prospective marker for post-transfer development, either alone or in conjunction with other embryo quality assessment tools. This is necessary to maximise the opportunity of couples to have a healthy child from assisted reproduction technology (ART) and for livestock breeders ...

The effect of transferring a poor-quality embryo together with a good-quality embryo on the singleton birth weight: A retrospective cohort study

International Journal of Reproductive BioMedicine, 2022
Background: Embryo quality may affect birth weight among neonates born through assisted reproductive technology. There are very limited studies assessing the adverse effect of transferring a poor-quality embryo with a good-quality one on neonatal ...

An increase of phosphatidylcholines in follicular fluid implies attenuation of embryo quality on day 3 post-fertilization

BMC Biology, 2021
Background Although oocyte quality is the dominant factor determining embryo quality, few studies have been conducted to evaluate embryo quality based on the metabolites related to the oocyte. With quantification of the follicular fluid (FF) metabolites,

Culture and quality control of embryos [PDF]

Human Reproduction, 1998
Improvement of embryo quality during in-vitro culture can be achieved by understanding and controlling the requirements of gametes and embryos. The most obvious route is to alter culture media, but standardization could be influenced by diverse environmental factors.

Sperm-specific protein ACTL7A as a biomarker for fertilization outcomes of assisted reproductive technology

Asian Journal of Andrology, 2022
Obtaining high-quality embryos is one of the key factors to improve the clinical pregnancy rate of assisted reproductive technologies (ART). So far, the clinical evaluation of embryo quality depends on embryo morphology.

Effect of the Air Filtration System Replacement on Embryo Quality in the Assisted Reproduction Laboratory [PDF]

Revista Brasileira de Ginecologia e Obstetrícia, 2018
Improving infrastructural conditions of the in vitro fertilization laboratory, such as the air quality, has profound positive effects on embryo culture. Poor environmental conditions reduce the rate of embryo formation and, therefore, of pregnancy.

Cell-Free DNA as a New Biomarker of IVF Success, Independent of Any Infertility Factor, Including Endometriosis

Diagnostics, 2023
Cell-free DNA fragments detected in blood and in other biological fluids are released from apoptotic/necrotic cells. In this study, we analyzed cfDNA levels in follicular fluid (FF) samples from patients with infertility.

Poor Embryo Quality Is Associated With A Higher Risk of Low Birthweight in Vitrified-Warmed Single Embryo Transfer Cycles

Frontiers in Physiology, 2020
BackgroundPrevious studies have reported the association between embryo quality and perinatal outcomes in fresh cycles, after cleavage-stage or blastocyst embryo transfer, and found no significant difference.
