Follicular microenvironment is paramount in the acquisition of oocyte competence, which is
dependent on two interconnected and interdependent processes: nuclear and cytoplasmic …

Although puberty can occur as early as 14–15months of age, depending on breed and use,
the reproductive career of mares may continue to advanced ages. Once mares are used as …

Introduction: Oocyte quality and fertility decline with advanced maternal age. During
maturation within the ovarian follicle, the oocyte relies on the associated somatic cells …

Dietary supplementation is the most feasible method to improve oocyte function and
developmental potential in vivo. During three experiments, oocytes were collected from …

Abstract Background Phospholipase C zeta (PLCZ1) is considered the major sperm‐borne
oocyte activation factor. Cryopreserved stallion spermatozoa are commonly used for …

The cloning of horses is a commercial reality, yet the availability of oocytes for cloned
embryo production remains a major limitation. Immature oocytes collected from abattoir …

The human female reproductive lifespan significantly diminishes with age, leading to
decreased fertility, reduced fertility quality and endocrine function disorders. While many …

Obesity is a growing concern in human and equine populations, predisposing to metabolic
pathologies and reproductive disturbances. Cellular lipid accumulation and mitochondrial …

The lipidomic secretions of embryos provide a unique opportunity to examine the cellular
processes of the early conceptus. In this study we profiled lipids released by the early …

Introduction: Oocytes and follicular somatic cells within the ovarian follicle are altered during
maturation and after exposure to culture in vitro. In the present study, we used a nontargeted …
