Institute of Sexual Medicine and Forensic Psychiatry and Psychotherapy


  • Prof. Dr. med. Aglaja Stirn

The Insitute of Sexual Medicine and Forensic Psychiatry and Psychotherapy is affiliated with the Zentrum für Integrative Psychiatrie (ZIP - Centre for Integrative Psychiatry). Patients with the following disorders are treated at the institute:

  • female and male sexual dysfunction (e.g. low libido, erectile dysfunction, lubrication disorders, vaginisimus, premature ejaculation, orgasm disorders, increased sexual desires), also due to physical illness such as diabetes mellitus, Parkinsons, hormonal illnesses or because of relationship issues.
  • gender identity disorders (transsexualism, transvestitism, disorders of gender identity in children)
  • problems in discovering sexual identity (referred to as coming-out problems)
  • deviant sexual interests (paraphilia, such as paedophilia, exhibitionism or fetishism)
  • sexual abusive behaviour (stalking, sexual assault, rape)

The Institute's research areas are, on the one hand, the biopsychosocial foundations of human sexuality and, on the other, the causes of sexual disorders, which for the most part are still not fully understood. Our research is currently focused on neuroscientific investigations on paedophilia and the influence of higher cortical processes in response to sexual stimuli. The latter could help to clarify a huge range of clinical manifestations of human sexuality, from willingness to participate in prostitution, sexual dysfunction, to sexually abusive behaviours. The investigations are conducted using psychological questionnaires, reaction measurements on the genitals (phallometry and vaginal plethysmography), EEG and MRT.

The Institute offers four lectures to students of Medicine, Law, Psychology, Education and Biology: General and forensic sexual medicine (Parts 1 and 2), Biopsychosocial fundamentals of sexual orientation and gender identity (Parts 1 and 2). Students of Medicine and Psychology can obtain a Certificate in Sexual Medicine by also attending two seminars (Treatment of sexual disorders, Parts 1 and 2) and passing an oral examination.
