Teleost fish reproduction is internally regulated by a hierarchical and orchestrated system, the hypothalamus-pituitary-gonad (HPG) axis. At the hypothalamic level, the regulation occurs by the gonadotropin releasing hormone (Gnrh), which stimulates the secretion of follicle-stimulation hormone (Fsh) and luteinizing hormone (Lh) from the pituitary. They reach the bloodstream and activate …
The study on fish reproduction gained importance in last years due the possibility of manipulation of the reproductive process, especially in endangered species. During this process, Kisspeptin regulated hypothalamic neurons produce GnRH, which stimulates the pituitary cells to release FSH and LH, which promote gonadal maturation. The GnRH, beyond the reproductive function, participates o…

In fish, in addition to the classical regulation by the luteinizing hormone (LH), the follicle stimulating hormone (FSH) is also a potent steroidogenic hormone and plays a role in inducing androgens release. Among the growth factors regulated by FSH, the Anti-Müllerian hormone (AMH) is a glycoprotein belonging to the Transforming Growth Factor Beta family (TGF²) and it is present in the S…
The reproductive biology of fish has several possibilities of approach, including analyzes of gonadal morphology that can be made at macro, micro and ultramicroscopic level. The comprehension of cellular modifications may be important in understanding the reproductive cycle. In females, the growth and maturation of ovarian follicles rely on a carefully designed communication between folli…
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…

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…
