New Case Report: Sertraline May Help Some Patients With Postorgasmic-Illness-Syndrome

A newly published case report in The Journal of Sexual Medicine describes two men with postorgasmic-illness-syndrome (POIS) whose symptoms improved significantly after treatment with sertraline. The authors suggest that serotonergic mechanisms may play a role in at least some forms of the condition.

Two Patients, Similar Symptoms

The report presents two men aged 28 and 29 who had experienced typical POIS symptoms since adolescence. Their symptoms included:

  • severe fatigue,
  • brain fog and cognitive impairment,
  • muscle pain,
  • mood changes,
  • flu-like malaise,
  • and social withdrawal.


Symptoms consistently appeared shortly after orgasm and lasted for several days. Both patients fulfilled the diagnostic criteria proposed by Waldinger and colleagues.

Previous Treatments Had Failed

In the first case, desloratadine and diclofenac had provided no benefit. The patient also suffered from social anxiety disorder. Sertraline was initiated and gradually increased to 150 mg daily. After three months, he reported a sustained reduction in both POIS symptoms and anxiety.

The second patient had lifelong premature ejaculation in addition to POIS. Sertraline was prescribed primarily for the ejaculatory dysfunction and increased from 25 mg to 100 mg daily. Within one month, he experienced a marked reduction in fatigue, weakness, muscle pain, and mood-related symptoms. According to the authors, the therapeutic effect remained stable over a three-year follow-up period.

How Could Sertraline Work?

Sertraline belongs to the class of selective serotonin reuptake inhibitors (SSRIs). The authors speculate that several mechanisms may contribute to the observed improvement, including:

  • modulation of serotonergic and dopaminergic pathways,
  • effects on stress responses,
  • normalization of post-orgasmic neuroendocrine processes,
  • and possible anti-inflammatory actions.


They emphasize, however, that POIS is likely a heterogeneous condition. Consequently, serotonergic treatment is unlikely to be effective in all patients.

Important Limitations

As with all case reports, these findings should be interpreted with caution. Two individual cases cannot establish causality, nor do they prove that sertraline is an effective treatment for POIS in general.

Nevertheless, the report adds to a growing number of observations suggesting that SSRIs may alleviate symptoms in a subset of patients. Larger, controlled studies will be needed to identify which biological mechanisms are involved and which patients are most likely to benefit.

Our Take

Experiences with antidepressants vary considerably among POIS patients. While some individuals report substantial improvement, others experience little benefit or intolerable side effects.

This new publication further supports the idea that postorgasmic-illness-syndrome is unlikely to be a single disease entity. Instead, multiple biological mechanisms may underlie similar symptom patterns, and different subgroups of patients may respond to different therapeutic approaches.

Sertraline is therefore not a standard treatment for POIS. However, these cases provide another clue that serotonergic pathways may be relevant in at least some patients.
