We recently investigated two patients with diabetes and elevated serum prolactin levels in whom no cause of hyperprolactinaemia could be found. For this reason we measured fasting serum prolactin levels in 72 diabetic males and compared the results with those of 63 healthy males and 90 nondiabetic males attending an Impotence Clinic. The diabetic group had significantly higher serum prolactin l...

BACKGROUND The impact of hyperprolactinaemia on endometrial function, along with embryo implantation, has been the subject of discussion. This article examines whether experimental hyperprolactinaemia can affect mouse ovarian function, endometrial pinopodes and embryo implantation. METHODS For pinopode analysis, 60 female mice were randomly divided into two groups: control (vehicle) and exper...

BACKGROUND Hyperprolactinaemia is a troublesome side-effect of treatment with antipsychotics. AIMS This double-blind, placebo-controlled study aimed at examining the effect of adjunctive treatment with 10 mg aripiprazole on prolactin levels and sexual side-effects in patients with schizophrenia symptomatically maintained on risperidone. METHOD Thirty patients taking risperidone were enrolle...

The effect of hyperprolactinaemia on the prostate has still not been fully elucidated. The aim of the study was to estimate the influence of hyperprolactinaemia on expression of the androgen receptor (AR) in rat epithelial cells of the prostate lateral lobe and on the morphology of these cells. Studies were performed on sexually mature male Wistar rats. To provoke hyperprolactinaemia rats recei...

BACKGROUND Antipsychotic drugs are associated with sexual dysfunction but the mechanisms are poorly understood. AIMS To ascertain the frequency of sexual dysfunction in patients taking conventional antipsychotics and to determine the possible underlying mechanisms. METHOD Sexual dysfunction was assessed in 101 patients receiving conventional antipsychotic medication, 57 normal controls and ...

It is now well established that hyperprolactinaemia is not rare and in the majority of cases is caused by a pituitary tumor, a prolactinoma. However, despite a plethora of relevant publications there are still certain questions that have not been adequately addressed: 1. What is the upper normal level of serum prolactin beyond which the condition should be characterized as hyperprolactinaemia r...

Twenty five patients with hyperprolactinaemia were treated with pergolide mesylate, a new dopamine receptor agonist. Twenty three received treatment for six to 20 months, and in all serum prolactin concentrations were considerably reduced. In most patients prolactin concentrations were maintained in the normal range by a low, once daily dose of pergolide and reversal of associated reproductive ...

The physiological importance of and therapeutic interest in dehydroepiandrosterone (DHEA) has been predominantly in relation to its action as an inhibitor of the promotion and progression of several kinds of tumours, including those of breast, prostate, lung, colon, liver and skin tissues. The aim of the present study was to determine the role of DHEA in diethylstilboestrol (DES)-induced pituit...
