A single case report describes a 28‑year‑old man with lifelong anorgasmia who finally had an orgasm after taking the female‑focused drug flibanserin for about a month. He also reported nighttime urination and trouble sleeping, and his overall sexual satisfaction barely changed.

Anorgasmia is a poorly understood phenomenon defined as either a lifelong or acquired consistent inability to achieve ejaculation. Despite the prevalence of anorgasmia, there is currently no established treatment for the condition. To report a unique case of a patient with lifelong anorgasmia who was able to achieve his first orgasm with off-label use of flibanserin. The present case study relies on the patient's self-report and a review of the relevant literature. The patient provided written informed consent. A 28-year-old male presented to our office with complaints of lifelong anorgasmia, without any signs of erectile dysfunction. He reported good libido and energy levels and denied any urinary symptoms or history of depression. The patient failed medical management with numerous off-label medications, including bupropion and bremelanotide. Despite having received 4 or 5 sex therapy sessions over 3 months, the patient reported that this treatment approach was not effective. Off-label use of flibanserin was then initiated, and after 28 to 32 doses over 4 weeks, he achieved his first orgasm. Notably, the patient experienced nocturia and insomnia. The follow-up International Index of Erectile Function score marginally improved by 2 points without any improvement in the overall satisfaction subdomain. This case highlights the challenges of managing anorgasmia and anejaculation in a young male patient. A stepwise approach involving pharmacotherapy and sex therapy was not successful. However, the off-label use of flibanserin ultimately resulted in the patient achieving his first orgasm, albeit with some side effects. Further studies are needed to evaluate the efficacy and safety of flibanserin in men for this indication.
