Background Oocyte growth is accompanied by follicular development in mammalian
ovaries. Since the discovery of two oocyte‐derived factors, growth differentiation factor 9 …

The environment that the cumulus oocyte complex (COC) is exposed to during either in vivo
or in vitro maturation (IVM) can have profound effects on the success of fertilisation and …

The ovarian follicle is the basic functional unit of the ovary, comprising theca cells and
granulosa cells (GCs). Two different types of GCs, mural GCs and cumulus cells (CCs) …

The large offspring syndrome (LOS) is observed in bovine and ovine offspring following
transfer of in vitro-produced (IVP) or cloned embryos and is characterized by a multitude of …

Obesity, diabetes, and related metabolic disorders are major health issues worldwide. As
the epidemic of metabolic disorders continues, the associated medical co-morbidities …

The objective of this study was to examine the time during the postfertilization period that
gene expression patterns in in vitro-cultured bovine embryos diverge from those of their in …

Heat stress is one of the main threats to dairy cow production; in order to resist heat stress,
the animal exhibits a variety of physiological and hormonal responses driven by complex …

The effects of the embryo production system on growth and transcription rate of day 7 and 16
bovine embryos were investigated. In vivo‐(controls) and in vitro‐produced (IVP) embryos …

The preimplantation bovine embryo is initially under the control of maternal genomic
information that is accumulated during oogenesis. The genetic programme of development …

Aromatase is the enzyme complex that catalyses the synthesis of oestrogens from
androgens, and therefore it has unique potential to influence the physiological balance …
