Introduction. Education in human sexual physiology and pathology, as well as own sexual health of medical doctors determines in a large proportion the ability to talk with patients about their sexual disorders. Therefore the authors considered important to collect and assess data regarding sexual health and development of Medical Faculty students. Aim. Analysis of selected aspects of psychosexual development and sex life of IVth grade medical students. Methods. We applied the self-report Questionnaire of Satisfaction with Sexual Life (KSS2), an instrument created to assess sexual problems in patients treated with group psychotherapy. Medical students filled the questionnaire when attending the courses of Psychopathology of neurotic disorders or Psychotherapy. Results. Analysis of the collected data revealed a relatively high differentiation of the studied group in regard of satisfaction and experiences with sexual life, attitudes towards masturbation, relationships and sexual activity. Regarding some aspects, significant differences between women and men occurred. Conclusions. A set of factors were identified, some of them may negatively influence medical doctor's competencies in the domain of sexual health. These are not having sexual debut or even lack of any erotic experiences and lack of sexual satisfaction. The results indicate a significant prevalence of factors, which may impede students education as well as taking into consideration the sexual issues during the medical interview. Assessment of influence of students' and doctors' own sexuality on their competencies in diagnostics and treatment requires further studies.
