The ultrasound technology has been used for various functions particularly as a tool in beef and dairy research for many years. It has become more available to the commercial livestock agriculture recently. Application of transrectal real-time ultrasonography in the study of bo‐ vine reproduction represents a technological breakthrough that has revolutionized the knowledge of reproductive biolo...

Obesity can impact on reproductive functions by causing hormonal imbalance and ovulatory dysfunction. Furthermore, obesity is associated with a range of adverse health consequences. There is a tight coupling between the reproductive system and energy balance. Obesity results from chronic imbalance between energy intake and energy expenditure, and therefore changes in energy expenditure impact o...

According to the Cort-Fitness Hypothesis, higher stress levels (glucocorticoids) in vertebrates are correlated to lower fitness. However, recent studies have failed to validate this hypothesis. A proposed wider framework suggests that reproduction can be perceived as an overload adds up to other environmental challenges that individuals must adjust to. In this case, elevated glucocorticoids cou...

Cadherins are cell surface proteins that are directly involved in a wide variety of processes such as cell adhesion, cell sorting, cell survival, morphogenesis, formation of intercellular junctions, maintenance of tissue integrity and tumourigenesis. This review discusses the multiple functions of cadherins in reproductive tissues. Furthermore, the role of the intracellular signalling protein b...
