Abstract：
:This study examined whether female subjects who had balanced hormonal profiles and who were experiencing the characteristic fluctuation in estrogen and progesterone levels exhibited changes in auditory function unlike subjects who were using a low-dose combined estrogen and progesterone steroid. Threshold data at 500, 1000, and 2000 Hz and middle ear pressure measurements were obtained at three specific times during two consecutive menstrual cycles. Results indicated no significant auditory sensitivity or middle ear pressure difference between the two groups. However, middle ear pressure was found to be significantly higher for both groups, and auditory sensitivity was decreased on day 3 or 4 of the cycle. It was concluded that the natural increase in interstitial fluids which generally begins 4 or 5 days before menses and culminates shortly after the onset of menses may be of sufficient magnitude to alter eustachian tube function and thereby affect middle ear status. :THis study was undertaken to investigate the stability of auditory sensitivity in individuals whose estrogen and progesterone levels are held constant by treatment with anovulatory steroids, and in individuals with balanced hormonal profiles and exibiting the characteristic fluctuation in estrogen and progesterone levels during the menstrual cycle. Measurement of threshold data at 500, 1000, and 2000 Hz, and middle ear pressure were measured in both groups during 2 consecutive menstrual cycles. There were no significant differences between the 2 groups in auditory sensitivity or middle ear pressure. However, on day 3 or 4 of the cycle middle ear pressure was found to be higher, and auditory sensitivity lower for both groups. This phenomenon is apparently related to the increase in interstitial fluid which culminates after the onset of menses, but does not seem to be related to anovulatory treatment.
