Abstract
OBJECTIVE: Human menopausal gonadotropin (HMG) is one of the commonest drugs used for ovarian stimulation with no reports on the audio-vestibular system. This study aims to examine HMG on the hearing profile of patients planning intracytoplasmic sperm injection (ICSI).
METHODS: This prospective study was conducted from June 2016 to June 2017 in a tertiary referral hospital. The audio-vestibular system of a total of 30 patients was evaluated using pure tone audiometry, distortion product otoacoustic emissions (DPOAEs in the form of a DP-gram) and Vestibular-evoked myogenic potential (VEMP) immediately before therapy and at the day 10 after therapy. Audio-vestibular adverse effects including hearing loss, tinnitus, vertigo, and otalgia were also considered.
RESULTS: Significant elevations in hearing thresholds were found on comparing thresholds at the day 10 at the onset of the study. The elevations were mostly at frequencies (1000, 2000 and 8000Hz) and did not affect speech perception. For DPOAE, significant differences were observed at all F2 frequencies on comparing both amplitudes and signal to noise ratios. Otologic complaints were significant for tinnitus and hearing loss.
CONCLUSION: Significant auditory and vestibular adverse effects may result from HMG therapy, indicating the importance of prompt monitoring of auditory functions in these patients.
