Similarly to other vertebrates, the androgen testosterone (T) is present in teleost fishes. In
addition, 11-oxygenated androgens, especially 11-ketotestosterone (11KT) are present …

Gonadotropin-releasing hormone (GnRH, previously called leutinizing hormone-releasing
hormone, LHRH) is the final common signaling molecule used by the brain to regulate …

The present chapter is devoted to the central nervous system of holostean and teleostean
fishes. Holostean species are restricted to only two genera, ie Lepisosteus (the gars), with …

Sexual behavior is one of the most profound events during the life cycle of animals that
reproduce sexually. After completion of gonadal development that is mediated by various …

Species that employ sexual reproduction must synchronize gamete maturity with behavior
within and between genders. Teleost fishes solve this challenge by using reproductive …

The role of androgens in vertebrate females has been overlooked until recently. We
examine the functional significance of androgens in females by reviewing studies that …

Teleost fish exhibit remarkably diverse and plastic patterns of sexual development. One of
the most fascinating modes of plasticity is functional sex change, which is widespread in …

The study of sex differences has produced major insights into the organization of animal
phenotypes and the regulatory mechanisms generating phenotypic variation from similar …

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

Plasma profiles of several gonadal steroids and cortisol were examined in a field population
of the protandrous, sex-changing anemonefish Amphiprion melanopus to elucidate potential …
