Sex differences in cell number in the preoptic area of the hypothalamus (POA) are
documented across all major vertebrate lineages and contribute to differential regulation of …

Sex differences in the anatomy and physiology of the vertebrate preoptic area (POA) arise
during development, and influence sex-specific reproductive functions later in life. Relative …

In diandric sex‐reversing fishes, sexually active males and females (primary phase)
regularly transform into an alternative reproductive morph, terminal‐phase males, that are …

The 2 pituitary gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone
(LH), regulate the reproductive function in all vertebrates. While many studies have …

In the preoptico-hypothalamic area (POA) of teleost fish, neurons containing gonadotropin-
releasing hormone (GnRH) regulate reproduction through direct projections to pituitary …

Many fish species exhibit natural sex change as part of their life, providing unique
opportunities to study sexually-differentiated social behaviors and their plasticity. Past …

The populations of gonadotropin-releasing hormone (GnRH)-producing cells within the
preoptic area (POA) and terminal nerve (TN) of the brain have been suggested as the …

Anemonefishes are monogamous protandrous hermaphrodites that live in societies
structured by size-hierarchies that function as breeding queues. Within each group, the …

Background: Encompassing about half of the 60,000 species of vertebrates, fish display the
greatest diversity of sex determination mechanisms among metazoans. As such that phylum …

Our understanding of the diversity of sexual strategies occurring in nature has increased
dramatically in the last years. This is particularly true in the area of determination of an …
