A psychoendocrine study in male paranoid schizophrenics with delusional ideas of homosexual content
Abstract:
The serum prolactin (PRL), luteinizing hormone (LH), testosterone (T) and estradiol (E) levels were investigated in a group of male paranoid schizophrenics with delusional ideas of homosexual content, in a group of male paranoid schizophrenics without delusional ideas of homosexual content, and in a group of healthy, male heterosexual subjects. Only male paranoid schizophrenics with delusional ideas of homosexual content had significantly lower serum PRL values and significantly higher serum E levels than those of the age-matched group of normal, male heterosexual controls; also, these patients tended to have higher (though not to a statistically significant degree) serum LH and T levels than those of normal controls. Findings of this study are discussed within the framework of the possible involvement of endocrine factors in the occurrence of delusional ideas of homosexual content in male patients with paranoid schizophrenia.
