    Abstract:
    To evaluate hypothalamic-pituitary-gonadal axis in acute schizophrenia, plasma FSH and LH concentrations were estimated both in basal conditions and after stimulation with gonadotropin releasing hormone (GnRH, 200 micrograms i.v.) in 14 young male patients with acute schizophrenia and in a age-matched group of 14 healthy male controls. Basal plasma PRL and testosterone levels were also measured. The mean basal levels of LH and FSH were slightly lower in schizophrenics, while the mean testosterone and prolactin levels were similar in the two groups. The FSH response to GnRH was significantly reduced in patients with acute schizophrenia, while the response of LH was similar in schizophrenics and in the controls. The possible significance of these findings is discussed in the contest of the complex neuroendocrine regulation of gonadotropin secretion and the overactivity of dopaminergic systems in acute schizophrenia.
