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.

Individually cultured bovine embryos produce extracellular vesicles that have the potential to be used as non-invasive embryo quality markers.

Theriogenology, 2020
Extracellular vesicles (EVs) are membrane-bound biological nanoparticles (NPs) and have gained wide attention as potential biomarkers. We aimed to isolate and characterize EVs from media conditioned by individually cultured preimplantation bovine embryos

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.

Well-of-the-well (WOW) versus polyester mesh (PM): a comparison of single-embryo culture systems in bovines

Revista Colombiana de Ciencias Pecuarias, 2022
Background: Mexico is innovating in the livestock industry through in vitro generation of bovine embryos with technologies such as well-of-the-well (WOW) and polyester mesh (PM) single-embryo culture systems. These techniques allow to maintain embryos in

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

Do Seminal Isoprostanes Have a Role in Assisted Reproduction Outcome?

Life, 2021
F2-isoprostanes (F2-IsoPs), stereoisomers of prostaglandin F2α generated by the free radical-induced oxidation of arachidonic acid, have been associated with different male infertility conditions.

The impact of embryo quality on singleton birthweight in vitrified-thawed single blastocyst transfer cycles.

Human Reproduction, 2020
STUDY QUESTION Does the quality of a single transferred blastocyst affect singleton birthweight in frozen-embryo transfer (FET) cycles? SUMMARY ANSWER The transfer of a poor-quality blastocyst was associated with lower mean birthweight and gestation ...
