title: Improvement of oligoasthenozoospermia in epileptic patients on switching anti-epilepsy medication from sodium valproate to phenytoin.
abstract: We present two cases of infertile male patients with oligoasthenozoospermia who were receiving anti-epilepsy medication. Complete reversal of the spermatic dysfunction followed by a successful conception was achieved after discontinuation of sodium valproate, suggesting that the drug was responsible for spermatic dysfunction in these individuals.
