AMH as a Predictor of Follicle Turnover, Embryo Quality, and Pregnancy Outcomes: A Retrospective Analysis [PDF]

Biomedicines
Background/Objectives: Infertility affects ~10–15% of couples of reproductive age, and assisted reproductive technologies (ARTs) increasingly rely on biomarkers to individualize care.

Effect of Day 3 and Day 5/6 Embryo Quality on the Reproductive Outcomes in the Single Vitrified Embryo Transfer Cycles

Frontiers in Endocrinology, 2021
ObjectiveTo explore the live birth rate and neonatal outcome after single vitrified blastocyst transfer versus single vitrified cleavage-stage embryo transfer at different grades of embryo quality.MethodsA retrospective cohort study including 6077 single

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.

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,

Endometrial stromal cells of women with recurrent miscarriage fail to discriminate between high- and low-quality human embryos [PDF]

, 2012
Background The aetiology of recurrent miscarriage (RM) remains largely unexplained. Women with RM have a shorter time to pregnancy interval than normally fertile women, which may be due to more frequent implantation of non-viable embryos.

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.

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).

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.
