Fish have been of paramount importance to our understanding of vertebrate comparative
neuroendocrinology and the mechanisms underlying the physiology and evolution of …

Most endocrine systems in the body are influenced by the hypothalamic-pituitary axis. Within
this axis, the hypothalamus delivers precise signals to the pituitary gland, which in turn …

Microplastics (MPs) have become a global issue as they are omnipresent in the ocean. Fish
ingesting MPs through feed could be affected in their physiological function, eg, disrupted …

Often referred to as “the master gland”, the pituitary is a key organ controlling growth,
maturation, and homeostasis in vertebrates. The anterior pituitary, which contains several …

Gonadotropin-releasing hormone (Gnrh) plays a major role in the regulation of physiological
and behavioural processes related to reproduction. In the pituitary, it stimulates …

Temperature plays a pivotal role in the control of seasonal reproduction in temperate fish
species. It is well known that temperatures that exceed a certain threshold impair gonadal …

Abstract “Brain sex differentiation” in teleosts is a contentious topic of research as most of the
earlier reports tend to suggest that gonadal sex differentiation drives brain sex …

Depending on the stage of gonad maturation, as well as other factors, gonadal steroids can
exert either a positive or negative feedback at the brain and pituitary level. While this has …

The gonadotropin-releasing hormone (GnRH) is essential during pubertal onset, for its
regulation of the synthesis and release of pituitary gonadotropins. Its action is mediated by …

Bisphenol A (BPA) and tetrabromobisphenol A (TBBPA) are widely used industrial
chemicals, ubiquitously present in the environment. While BPA is a well-known endocrine …
