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 ...

Does a poor-quality embryo have an adverse impact on a good-quality embryo when transferred together?

Journal of Ovarian Research, 2018
Background In some in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) cycles, we may consider transferring one poor-quality embryo with one good-quality embryo. Previous studies have indicated that the poor-quality embryo transferred

Embryo Aggregation in Pig Improves Cloning Efficiency and Embryo Quality [PDF]

PLOS ONE, 2016
Dans cette étude, nous avons analysé les effets de l'agrégation d'embryons clonés sur le développement embryonnaire in vitro et la qualité de l'embryon en mesurant le diamètre et le nombre de cellules du blastocyste, les niveaux de fragmentation de l'ADN et l'expression des gènes associés à la pluripotence, à l'apoptose, au trophoblaste et à la ...

Effect of frozen-thawed embryo transfer with a poor-quality embryo and a good-quality embryo on pregnancy and neonatal outcomes

Reproductive Biology and Endocrinology
Abstract Background To evaluate the impact of embryo quality and quantity, specifically a poor quality embryo (PQE) in combination with a good quality embryo (GQE), by double embryo transfer (DET) on the live birth rate (LBR) and neonatal outcomes in patients undergoing frozen-thawed embryo transfer (FET) cycles.

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.

Influence of cleavage-stage embryo quality on the in-vitro fertilization outcome after single embryo transfer in fresh cycles

Taiwanese Journal of Obstetrics & Gynecology, 2020
Objective: Embryo quality is crucial for determining the outcome of embryo implantation. This study aimed to assess the impact of embryo quality on the outcome of in vitro fertilization/single-embryo transfer (IVF-SET).

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.
