Post-ejaculatory pain syndrome.

The clinical features of psychogenic post-ejaculatory pain are described and some hypotheses regarding the etiology of this rare, distressing sexual disorder of men are offered. The source of the pain appears to involve the involuntary spasm of certain muscles of the male genitalia, which can be triggered by a variety of psychosexual conflicts. The syndrome of post-ejaculatory pain is considered within a continuum of psychogenic ejaculatory disorders, which range from the most severe impairment--retarded ejaculation (RE)--to the mildest--premature ejaculation (PE).
