A great deal of information is known regarding the process of sex differentiation in fish, and
the mechanisms involved in primary sex determination are now beginning to be defined. A …

Neurohormones similar to those of mammals are carried in fish by hypothalamic nerve fibers
to regulate directly follicle-stimulating hormone (FSH) and luteinizing hormone (LH) …

The pituitary gland controls many important physiological processes in vertebrates,
including growth, homeostasis, and reproduction. As in mammals, the teleost pituitary …

The secretion of gonadotropins, the key reproductive hormones in vertebrates, is controlled
from the brain by the gonadotropin-releasing hormone (GnRH), but also by complex steroid …

The effect of steroid hormone treatment on coho salmon (Oncorhynchus kisutch) was
examined. The cDNAs for coho salmon FSH β and LH β subunits were cloned and …

The pituitary gonadotropins luteinizing hormone (LH) and follicle-stimulating hormone (FSH)
regulate steroidogenesis and spermatogenesis by activating receptors expressed by Leydig …

Two distinct gonadotropins (GTHs) have been demonstrated in a number of teleost fishes.
Although the physiological roles of GTHs have been extensively studied in salmonids, little …

Sex steroids are involved in all aspects of the regulation of reproductive processes in
vertebrates. Teleost fish produce several types of bioactive gonadal steroids, including …

Recently, zebrafish has quickly risen as a model species for functional analysis of the brain–
pituitary–gonad axis. However, one of the hurdles for such work in this popular model …

Pubertal maturation of the male reproductive system is associated with the development to
functional competence of the brain–pituitary–gonad (BPG) axis, the endocrine system that …
