Heat stress affects oocyte developmental competence and is a major cause of reduced fertility in heat stressed cattle. Negative effects of heat stress on the oocyte have been observed at morphological, biochemical and developmental levels. However, t

Within the cervical and lumbar spinal enlargements, central pattern generator (CPG) circuitry produces the rhythmic output necessary for limb coordination during locomotion. Long propriospinal neurons that inter-connect these CPGs are thought to secu

Reduced reproductive performance is one of the main effects caused by heat stress in cattle. Its negative effects have been observed at the transcriptional, biochemical, morphological, and developmental levels on the oocyte and embryo. There are no s

Cattle under the effect of heat stress have reduced fertility, with negative effects on the oocyte observed at the morphological, biochemical, transcriptional and developmental levels. There are no studies evaluating the effect of heat stress on the

It is known that animals under the effect of heat stress present reduced fertility. We aimed to investigate the effect of heat stress on the developmental competence and global gene expression profile of oocytes through the transition from spring to

Anti-mullerian hormone (AMH) has become an important tool for the selection of donors with high antral follicle count and high superovulatory response for in vivo or in vitro embryo production programs. The serum concentration of AMH is becoming a su

While vitrification has become a valuable system used in oocyte and embryo preservation, there is still much to be learned in optimizing this protocol. Both mature and immature oocytes can be vitrified but each presents challenging aspects. Mature oo

Although vitrification is becoming increasingly common for oocyte preservation, there has been recent evidence that some cryoprotectants may alter DNA methylation and so result in decreased oocyte developmental competence and abnormal embryonic devel

Progesterone is a key hormone in reproduction and plays a crucial regulatory role during the oestrous cycle and pregnancy. The effect of progesterone on the developmental competence of bovine oocytes is yet to be fully understood. Molecular tools mig

Modulators of 3′-5′-cyclic adenosine monophosphate have been extensively researched to delay nuclear maturation in in vitro maturation (IVM) systems to improve synchronization of nuclear and cytoplasmic maturation. However while normal maturation
