Culture and quality control of embryos [PDF]

open access: yesHuman 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

open access: yesAsian 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]

open access: yesRevista 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

open access: yesDiagnostics, 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.

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

open access: yesRevista 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?

open access: yesJournal 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
