Case of post-orgasmic illness syndrome associated with hypogonadism.

INTRODUCTION: Post-orgasmic illness syndrome is a rare condition that occurs after ejaculation and persists for 2-7 days and is characterized by flu-like symptoms, which can significantly reduce quality of life. CASE PRESENTATION: A 21-year-old unmarried man was referred to our hospital due to flu-like symptoms that developed after ejaculation by masturbation and persisted for about 2 days. The patient's free testosterone level was slightly lower than normal. Nonsteroidal anti-inflammatory drugs were initially administered and helped relieve headache and muscle pain. Thereafter, the patient was able to ejaculate three times a week. In addition, after administering testosterone enanthate once or twice a month, his general fatigue significantly improved, and he could ejaculate every day. CONCLUSION: The pathophysiology of post-orgasmic illness syndrome has not been fully elucidated. The treatments for this condition must be accurately selected according to pathophysiology.
