  • Title: Disorders of reproduction in epilepsy--what can we learn from animal studies?
    Author: Taubøll E, Røste LS, Svalheim S, Gjerstad L.
    Journal: Seizure; 2008 Mar; 17(2):120-6. PubMed ID: 18155932.
    Abstract:
    Several animal studies have shown that both the epilepsy itself and many antiepileptic drugs (AEDs) affect reproductive endocrine function in both males and females. Epileptic activity may lead to arrested ovarian cyclicity, anovulatory cycles, polycystic ovaries, and endocrine changes in female animals. In males, seizures disturb normal reproductive physiology by inducing endocrine changes, alterations in gonadal size, and hyposexuality. Several AEDs also affect endocrine function, fertility, and gonadal morphology in both sexes. This paper reviews the literature regarding animal studies related to reproductive disorders in epilepsy. Although care should always be taken when applying data from animal experiments to the human situation, animal models provide a unique possibility for investigating the independent effects of the epilepsy itself and the effects of AEDs in isolation, without confounding factors. By constantly comparing results from clinical and animal studies, and by developing appropriate animal models, several mechanistic questions regarding the complex interplay between epilepsy, hormones, and AEDs can be explored. Animal experiments should play an integral part in the study of reproductive endocrine disorders in epilepsy.
