Control of testicular development is multifactorial and involves a number of hypothalamic, hypophyseal and peripheral hormones. Here, we investigated direct action of zebrafish gonadotropin-inhibitory hormone (zGnih) which ...

A radioimmunoassay (RIA) for the measurement of maturational gonadotropin (GtH II) in the plasma of rainbow trout was developed using a rabbit antiserum to b subunit of chum salmon GtH II. Intact GtH II was used as standard ...

The pituitary gonadotropins, Fsh (follicle-stimulating hormone) and Lh (luteinizing hormone), regulate testicular development and functions in all vertebrates. At the pituitary, different signaling systems regulate the ...

Gonadotropin-inhibitory hormone (Gnih) is known to play a role in the regulation of reproduction in vertebrates by influencing gonadotmpin release and synthesis. While the endocrine actions of Gnih have been identified in ...

Aim: Hormone replacement therapy with testosterone for pubertal induction in boys with congenital hypogonadotropic hypogonadism (CHH) achieves virilization but not spermatogenesis. By contrast, human chorionic gonadotropin ...

During the last two decades a large number of genetically modified mouse lines with altered gonadotropin action have been generated. These mouse lines fall into three categories: the lack-of-function mice, gain-of-function ...

Gonadotropin-releasing hormone (GnRH) is a decapeptide widely known for its role in regulating vertebrate reproduction by serving as a signal from the hypothalamus to pituitary gonadotropes. The first form of GnRH to be ...
