“…During their menstrual cycles, each woman underwent four ABR tests, the first at the menstrual phase (day 1-3), the second at the mid-cycle (day [11][12][13][14], the third at the mid-luteal phase (day 17-22) and the fourth at the pre-menstrual phase (day 25-27). A retrospective calculation of the approximate day of ovulation was done from the day of onset of the next menstrual cycle.…”

Background and Objectives: Brainstem Auditory Evoked Potentials (BAEP) show variations with age, sex and other physiological factors. The gonadal steroids may also alter the neuronal functioning, but an electrophysiological evidence is sparse. This study was undertaken to analyze the auditory evoked response in females of the reproductive age group during four different hormonal states of the menstrual cycle. Methods:This was a prospective, single centered, longitudinal study. The waves of BAEP were recorded in 50 young females (of the ages of 19-36 years, who used no hormonal therapy) during four different phases of the same menstrual cycle. The peak latencies of the waves, I, II, III, IV and V, IPL I-III, I-V and III-V and the amplitude ratio, V/I were recorded and statistically analyzed.Results: A significant increase in the peak latencies of the waves, I-V in the oestrogen peak mid cycle was observed, while a significant decrease in the progesterone peak mid-luteal phase was observed. However, IPL did not show any statistically significant change in the above two phases. All the parameters did not show significant changes in the menstrual and the premenstrual phases. Interpretation and Conclusion:The results indicated the BAEP changes in the mid follicular and the mid luteal phases of the menstrual cycle, thus suggesting the changes which were attributable to oestrogen and progesterone. INTRODUCTIONThe hormonal changes that occur in a short time span during a menstrual cycle, promote modifications all over a woman's body, with physical and emotional manifestations being frequently observed. There is a controversy over how the hormonal conditions influence the cerebral electrophysiology. Auditory Evoked Potentials (AEP) may serve as a non-invasive clinical tool in characterizing the electrophysiological phenomena of neural excitation, conduction and transmission across the auditory pathway.Ovarian hormones have long been known to affect the sensory information processing in the brain. The auditory perception being one of the sensory modalities, it also gets influenced by the sex hormones. Clinical observations strongly suggest that the changes in the gonadal function modify the auditory, olfactory and the taste thresholds [1]. The thresholds for touch, two point discrimination and the perception of light have also been found to vary during the follicular and the luteal phases of the menstrual cycle [2]. Variations in the different hormonal levels, especially in the levels of oestrogen and progesterone across the menstrual cycle, have been proposed to be responsible for the latency changes of the waves of the auditory evoked potentials [3].Several researchers have reported that the changes in the auditory acuity occur during the menstrual cycle. In an attempt to specify the critical functional components which are involved in the menstrual fluctuations, the evidence of a better performance in a variety of tasks at mid-cycle, was obtained in a study. It was also shown that some tasks were particularly s...

“…Most of the changes in women take place in the luteal phase; these changes include fluid retention, weight gain, increased energy demands, changes in glucose uptake, a slower gastrointestinal transit time, and hydrops of the labyrinth (due to sodium retention and the resulting endolymph hypertension). 4 5 6 7 8 9 10 …”

Introduction There is only limited information from previous studies that suggest that auditory function may be influenced by hormones. Recent advances in the field have exposed the potential role of hormones in modulating the auditory system. Objective This study aims to investigate the relationship between menstrual cycle and outer hair cell function with audiological examination. Methods This is an analytic study with a cross-sectional design. The sampling was a systematic random sampling. We found 49 women with normal menstrual cycle and collected their data through interviews, physical examination, and examination of the ear, with otoscopic and other routine otorhinolaryngology examinations. We evaluated Tympanometry, distortion-product otoacoustic emissions (DPOAE), and pure tone audiometry. Results We found the audiometric threshold worse in the follicular phase than other phases at 4000 Hz of the right ear, and in the ovulation was found best than any other phases at 1000 Hz of the left ear with significant difference. We found significant difference of DPOAE between ovulation time and follicular phase at 3000 Hz and 1000 Hz in the left ear and between ovulation and luteal phased at 2000 Hz, 3000 Hz and 5000 Hz in the right ear and at 1000 Hz in the left ear with p < 0.05. Conclusion The result of this study showed that only a small part of audiometry threshold had a significant difference between each menstrual phase. In other words, we found no correlation between menstrual and audiometry threshold. Nonetheless, there is a correlation between menstrual cycle phase and DPOAE amplitude.
