Özet

The authors planned to show the effect of high-level estrogen on cognitive functions, using P300 in the in-vitro fertilization (IVF) population. Eighteen IVF patients (mean age 31.39+/-5.01) without any detectable cognitive disorder were enrolled in this study. The authors measured N100, P200, N200, P300 latencies and amplitudes at C-z and F-z recordings during the lowest and highest blood estradiol levels. P300 amplitudes were significantly reduced during the highest level of estradiol compared to the lowest level both at F and C, recordings. The other subcomponents of P300 were not significantly influenced by blood estradiol levels. The results revealed a decline in the ability of task relevance and state of arousal when the estradiol level was the highest in the IVF patients.
