title: Effects of long-term treatment with metergoline in patients with idiopathic oligospermia.
abstract: The effect of metergoline, an ergoline derivative with antiserotonin as well as dopaminergic properties, was studied in forty-five male patients with idiopathic oligospermia. Metergoline treatment (6 mg daily for 5 months) had no demonstrable effect on spermatogenesis; moreover, it did not influence the serum levels of LH, FSH, testosterone and oestradiol although it significantly reduced prolactin levels. It is concluded that, in all likelihood, serotonin plays little or no part in the pathogenesis of idiopathic oligospermia and that pharmacological reduction of normal prolactin levels has no therapeutic effect on this disease.
