Abstract     Estrogens increase after puberty and remain at high levels in the reproductive period and decrease with menopause. These changes occuring in the level of estrogens affect dopamine metabolism indirectly by causing changes in cathecholamine sensitivity of the brain. To assess the role of estrogens on the formation of pattern reversal evoked potentials (PRVEPs), three groups of patients were considered: prepubertal group, reproductive age group and postmenopausal group. PRVEPs of all subjects were recorded. Mean latency was shortest in the reproductive age. While no statistical difference was present between the mean latencies of prepubertal and the reproductive period groups, the mean latencies of both of these groups were statistically significantly shorter than that of the postmenopausal group (p<0. 005).
