PRL and hyperprolactinemia: Karunakaran et al. [7] found that, among menopausal women, 45% normalized PRL off treatment, compared with only 7% of women with preserved ovarian function; however, patients in Karunakaran’s study were quite heterogeneous in regard to hyperprolactinemia etiology (idiopathic vs. microprolactinoma) and to previous treatment (surgery vs. dopamine agonists vs. no treatment); in fact, among postmenopausal women, only 7/11 had received dopamine agonists, while two had undergone surgery.
