Effects of valproate or lamotrigine monotherapy on the reproductive endocrine and insulin-related metabolic profile in Chinese adults with epilepsy: a prospective randomized study.

摘要

Cross-sectional studies have suggested that valproate treatment may be associated with hyperinsulinemia and hyperandrogenism in women. Few prospective data are available. We evaluated the reproductive endocrine and insulin-related metabolic parameters in men and women with untreated epilepsy randomized to valproate (n=44) or lamotrigine (n=37) monotherapy for 12 months. On treatment, there was no significant difference in fasting serum insulin concentrations between the two groups. In women (n=40), there was no significant difference between the two groups in change from baseline in serum total testosterone, dehydroepiandrosterone sulfate, luteinizing hormone, or follicle-stimulating hormone. In men (n=41), follicle-stimulating hormone concentration significantly decreased in patients taking valproate compared with those on lamotrigine as early as 3 months after treatment. Greater attention should be paid to investigate the potential impact of valproate on reproductive function in men.
