[Prolactinoma causing erectile dysfunction].

INTRODUCTION

Hyperprolactinaemia is an unusual cause of erectile dysfunction, yet erectile dysfunction is a common complaint in patients with hyperprolactinaemia. We present a patient with erectile dysfunction without symptoms suggesting hyperprolactinaemia.

MATERIALS AND

METHODS

Patient consulted with erectile dysfunction for the past 10 years. Decreased time and quality of erection with an IIEF score of 14/30. Lab reports: prolactin 90.2 ng/ml, FSH 1.6 mlU/ml, LH 1.8 UI/L, total testosterone .491 ng/ml. Brain MRI: lateral pituitary micro adenoma, 5mm in diameter.

RESULTS

Patient in treatment with cabergoline 1mg per week, after treatment noticed improvement in erectile dysfunction and sexual desire. Actual prolactin 15.4 ng/ml.

CONCLUSIONS

Up to 5% of patients with erectile dysfunction are diagnosed with a pituitary adenoma. Erectile dysfunction caused by pituitary neoplasms is a multifactorial disease and elevated prolactin has consequences on testosterone, LH, FSH, and dopamine precursor levels.
