Background: Induction of ovulation in the course of infertility treatment is increasingly commonplace in the 21st century. As a consequence, it can be expected that previously unrecognized complications of the procedure will be reported.
Case: A 36-year-old woman presented with severe pelvic pain and hyponatremia after ovarian stimulation with gonadotropins. After admission with a presumptive diagnosis of ovarian hyperstimulation syndrome, a further family history revealed acute intermittent porphyria. A 24-hour urine collection confirmed the diagnosis.
Conclusion: Hormonal therapy for induction of ovulation in the course of infertility treatment may precipitate attacks of acute intermittent porphyria. A careful history must be undertaken prior to administration of such hormonal preparations.
