On the basis of a systematic assessment of characteristics of the mental state and the patho-logical syndromal structure of mental disorders, sexual function and the state of marital adap-tation in men with schizoid personality disorders (SPD), the Thesis shows characteristic fea-tures of somatosexual and psychosexual development, and the role of mental, psychological and negative socio-psychological factors in formation of general, interpersonal and sexual communication disorders, as well as family functioning characteristics. The findings obtained served as the ground for developing theoretical justifications and practical solutions for a sys-tem of differentiated psychotherapeutic correction and psychoprophylaxis of sexual dysfunc-tion (SD) and marital deadaptation (МD). The clinical manifestation of the SPD has the following clinical variations: hypohedonic, hypoemotional, asyntonic, asexual, metaphysical-introspective, socio-deprivative, and nihilis-tic. In addition, patho-syndromologic arranging, i. e. pseudoneurotic, obsessive-hypochondriac, anxious-depressive, obsessive-compulsive, obsessive-phobic and somatosensory types are formed via the secondary neurotization mechanism. General, interpersonal, and sexual communication disorders in the SPD are developed due to a constellation of psychopathological, pathopsychological and negative socio-psychological factors. The prevailing SD type in single men suffering from the SPD is erectile dysfunc-tion and loss of sexual pleasure, as well as absence or loss of sexual desire and orgasmic dysfunction. A non-functional marriage type prevails among men with the SPD. SD and MD variations and forms have been classified as follows: SD and MD constitutional varia-tion, SD and MD communicative and aversive form, and MD sociocultural variation (sex-role and sexual-erotic forms). Criteria for selection of psychotherapy methods, procedures and techniques, including aiatrogenicity, clinical reasoning, aheterosuggestivity, individualized approach, attributive intellectualization, autogenic modus, introspectiveness, longitudinal form and supportive-ness, have been elaborated. SPD psychotherapy in men should carry out in three stages (cor-rection of mental disorders, SD and MD) and include the following positions: influence scope / targets, psychotherapeutic method / procedure / psychotechnique, act of influencе and pharmacological background. The psychotherapeutic prevention system should be aimed at prevention of desadaptation due to the underlying disease, secondary neurotization, and development of different SD forms and МD variations. Keywords: schizoid personality disorder, men, sexual dysfunction, marital deadaptation, psychocorrection, psychoprophylaxis.
