BACKGROUND While oocyte IVM is practiced sporadically it has not achieved widespread
clinical practice globally. However, recently there have been some seminal advances in our …

To date, large‐scale use of multiple ovulation and embryo transfer (MOET) programmes in
ovine species is limited due to unpredictable results and high costs of hormonal stimulation …

Three-dimensional in vitro maturation (3D IVM) is a promising approach to improve IVM
efficiency as it could prevent cumulus-oocyte complex (COC) flattening and preserve its …

Developmental competence of in vitro matured cumulus oocyte complexes (COCs) in
conventional IVM (C. IVM) is lower than in vivo maturated COCs and is related to …

This review presents the latest advances in and main obstacles to the application of in vitro
embryo production (IVEP) systems in small ruminants. This biotechnology is an extremely …

In vitro maturation (IVM) is not a routine assisted reproductive technology (ART) for oocytes
collected from early antral (EA) follicles, a large source of potentially available gametes …

The specific role of the canonical WNT/β-catenin signaling pathway during the
preimplantation development of goat remains unclear. Our objective was to investigate the …

Oocyte maturation is a critical step in the completion of female gametogenesis in the ovary;
thus, for subsequent fertilization and embryogenesis. Vitrification of embryo also has been …

Background Oocytes of large animal species isolated from small ovarian follicles (< 2 mm)
are less competent to support early embryonic development after in vitro maturation and …

The culture media used throughout the in vitro production (IVP) of bovine embryos remain
complex. The serum added to culture media in order to improve embryo development …
