Abstract
The increasing release and detection of parabens in aquatic ecosystems, due to their widespread use in cosmetics, pharmaceuticals, and processed foods, has raised concerns about the effects of these compounds on the reproduction of aquatic organisms. Methylparaben (MeP), propylparaben (PrP), and 4-hydroxybenzoic acid (4-HB) are classified as emerging contaminants and possess lipophilic pr…

Abstract
Reproduction in teleost fish is regulated by the hypothalamus-pituitary-gonads axis (HPG). Under regulation of GnRH, the pituitary gland secrets two gonadotropins: follicle-estimulating (FSH) and luteinising hormones (LH), heterodimers formed by a common alpha subunit, and a beta subunit, which confers specific biological functions. The gonadotropins modulate the production of sex steroid…

Abstract
Fish gonadotropins (Fsh and Lh) and their receptors (Fshr and Lhr) play crucial roles in regulating the hypothalamus-pituitary-gonad (HPG) axis. Gonadotropins are secreted by the gonadotropic cells in the pituitary, are transported through the bloodstream, and -upon reaching the gonads- promote the activation of their cognate receptors, triggering events that will result in the control of…
