Case series: expanding diagnostic markers in postorgasmic illness syndrome

Introduction Postorgasmic illness syndrome (POIS) is a rare condition in which individuals develop generalized and flu-like symptoms after ejaculation. Several mechanisms and treatments for this disorder have been proposed but many questions remain.Aims We sought to present a summary of literature to date and highlight common symptoms, associated features, comorbidities, and laboratory findings in a clinical sample of patients with POIS.Methods We conducted a retrospective chart review of 6 patients with POIS in our clinic and presented compiled results.Results We identified newly described non-flu-like presentations, onset of symptoms with high states of arousal without ejaculation, and presence of psychiatric comorbidity in a majority of patients. We did not identify a postorgasm allergic response with bloodwork available.Conclusion POIS remains a poorly understood condition that likely comprises a number of different clinical entities. Further research on a larger clinical sample is necessary to better characterize POIS and understand its biological and psychological basis.
