In mammals, the neurohormonal control of the pituitary gonadotropes is provided by the gonadoliberin GnRH. Several studies on teleost fish indicate that a single positive control by GnRH is not a general rule among vertebrates. Peter and colleagues presented the first evidence of an inhibitory neuro...
