Transient otoacoustic emissions were evaluated by distortion product during the 3 phases of the menstrual cycle (luteal, follicular and ovulatory phases). The SPSS 13.0 software was used to analyze the data.Resultsthe phases of menstrual cycle do not alter the amplitude and reproducibility values of the transient otoacoustic emissions. We noticed a difference between the ears in the frequency of 1.5 KHz in the amplitude of emissions by distortion product, and the right ear showed the highest values.ConclusionThere are no significant differences in transient otoacoustic emissions and distortion products in the phases of the menstrual cycle.
