OBJECTIVE: To identify psychiatric diagnoses and psychosocial factors associated with intentional male genital self-mutilation (GSM) of specific injury subtypes.

METHODS: A search of MEDLINE, EMBASE, PsycINFO, PubMed, Web of Science and CINAHL for cases of GSM was conducted until December 2015, based on GSM and related terms. Cases were examined for injury subtype, psychiatric diagnosis and psychosocial factors. Chi-square analyses were employed to determine differences in frequency of such factors across injury subtypes.

RESULTS: Data were obtained from 173 cases: genital mutilation (n=21), penile amputation (n=62), castration (n=56) and combined amputation/castration (n=34). Common psychiatric disorders included schizophrenia spectrum (49%), substance use (18.5%), personality (15.9%) and gender dysphoric disorders (15.3%). Chi-square analyses revealed that schizophrenia spectrum disorders occurred significantly more often among auto-amputates as compared with self-castrators or mutilators. Gender dysphoria occurred significantly more often among self-castrators than auto-amputates. No significant differences emerged regarding psychosocial factors across GSM subtypes. However, associations were observed between psychosocial factors and psychiatric diagnoses. Although altogether not commonly reported, experiential factors were reported in 82% of psychotic individuals. Treatment inaccessibility was noted among 71% of gender dysphorics engaging in auto-castration.

CONCLUSION: Clinicians must consider the diverse range of psychiatric disorders and psychosocial factors underlying GSM.
