About

Background: Different antiepileptic drugs are responsible for reproductive dysfunction in male epileptic patients. The aim of this study is to evaluate the effect of valproate versus levetiracetam as a monotherapy on males' sex hormones and sperm parameters in newly diagnosed epilepsy. Methods: This comparative study included 50 newly diagnosed epileptic male participants from outpatient clinic of Neurology department of Zagazig University Hospitals. All participants were subjected to complete general and neurological examination, Doppler ultrasonography of the testis, pre and post treatment serum sex hormone assay and semen analysis. Post- treatment re- evaluation check point was determined if eight weeks have passed after the last seizures. This study included two groups, group I: 25 participants, were treated by valproate (VPA) as a monotherapy till became seizure free at the last 8-weeks before post treatment check-point, with ages ranged from 18-43 years. Group II: 25 participants were treated by levetiracetam (LEV) with the same regimens of valproate as a monotherapy, with ages ranged from 20-45 years.

Full description

Background: Epilepsy is a chronic neurological disorder characterized by recurrent epileptic attacks and researches have reported that the relation between epilepsy and the reproductive dysfunction is not yet completely understood. Seizures are linked with sexual dysfunction as part of the disease pathophysiology in these patients. Through epileptic discharge, hypothalamus receives signals from hippocampus, amygdala and cerebral cortex. Hypothalamic-pituitary axis signaling changes is leading to sex hormones release including follicle stimulating hormones and luteinizing hormone changes.

However, the available antiepileptic drugs (AED) have not yet been proven to have negative impacts on sexual function. Evaluation of AED induced sexual dysfunction is complicated, less than clear, and is hard to find. Sex hormone levels can be changed due to AEDs which are the cause of sexual dysfunction and reproductive disorders Different antiepileptic drugs are responsible for reproductive dysfunction in male epileptic patients. The aim of this study is to evaluate the effect of valproate versus levetiracetam as a monotherapy on males' sex hormones and sperm parameters in newly diagnosed epilepsy.
