The aim of this study was to cryopreserve by vitrification by propylene glycol (PROH) and dimethylsulfoxide (DMSO) immature bovine oocytes in straws and to investigate the effects of vitrification on post-thaw oocyte maturation and fertilization. A total of 983 cumulus oocyte complexes were obtained by follicle aspiration from 263 ovaries of cows ...

Recent Advances and Emerging Applications in Embryo Vitrification for Livestock
ABSTRACT Vitrification has progressively supplanted conventional slow freezing as the method of choice for embryo cryopreservation in both human medicine and animal production, particularly for in vitro‐produced embryos and for species or developmental stages highly sensitive to conventional freezing.

Sperm Recovery and Evaluation in Domestic Species: Challenges and Current Practices
ABSTRACT Semen collection is a key step in the development of assisted reproductive technologies (ARTs) in domestic mammals, as the collection method determines the functionality and fertility of the sperm. The artificial vagina or manual collection yields ejaculates similar to those obtained during natural mating, although they require prior training ...

ABSTRACT Equine follicular aspirates obtained during ovum pick‐up contain a heterogeneous mixture of mesenchymal stromal cells (MSC) and granulosa cells (GC). This study evaluates how selective isolation and expansion of MSC decrease GC populations.

ABSTRACT The efficiency of AI in sheep depends partly on maintaining sperm function during storage. This study compared INRA 96 and a skim milk‐based formulation for storing ram semen at 15°C for 6 h, evaluating sperm quality and IVF and field fertility outcomes. INRA 96 showed higher VCL, ALH, and sperm viability after 6 h of storage.

ABSTRACT Follicular aspirates have emerged as an alternative source of mesenchymal stromal cells (MSC) in mares; however, factors influencing successful MSC isolation remain unclear. This study evaluated whether reproductive cyclicity and follicle count affect MSC recovery from ovum pick‐up (OPU)‐derived follicular aspirates.
