Aggression is an essential social behavior that promotes survival and reproductive fitness
across animal systems. While research on the neuroendocrine mechanisms underlying this …

There is a well‐established positive relationship between gonadal steroids and aggression.
In some seasonally breeding species, however, aggression often persists or is increased …

An import role for gonadal steroid hormones, particularly testosterone, in mediating
aggressive behavior is well-established across vertebrate taxa. Due to the emphasis placed …

In 1849, Berthold demonstrated that testicular secretions are necessary for aggressive
behavior in roosters. Since then, research on the neuroendocrinology of aggression has …

Historically, research on the neuroendocrinology of aggression has been dominated by the
paradigm that the brain receives sex steroid hormones, such as testosterone (T), from the …

Testosterone (T) mediates aggression in a wide range of species. In some species,
however, aggressive behavior persists or increases during the non-breeding season when T …

The gonadal hormone testosterone (T) regulates aggression across a wide range of
vertebrate species. Recent evidence suggests that the adrenal prohormone …

Berthold's classic study of domesticated roosters in 1849 demonstrated that testicular
secretions are necessary for the normal expression of aggressive behaviour. Although this …

A contribution to a special issue on Hormones and Human Competition. The relationship
between androgenic hormones, like testosterone (T), and aggression is extensively studied …

Dehydroepiandrosterone (DHEA) is a testosterone/oestrogen precursor and known
modulator of vertebrate aggression. Male song sparrows (Melospiza melodia morphna) …
