Aim:
To co-relate the use of hormonal contraceptives with positive Auditory and Vestibular alterations.
Methods:
medical history taking, audiometric test and vestibular test was applied to 60 women between the ages of 14 and 35 years old, and 30 of these women are on oral hormonal contraceptive consisting of Estrogen and Progesterone (risk group), for 6 months or more, that had no Auditory or Vestibular complaints prior to the usage of hormones; and 30 women that had never used these hormones (control group), with no Auditory or Vestibular complaints. Medical history was used to select the sample.
Results:
Based on otoneurological findings, through quantitative research, we could see the prevailing Irritatative Peripheral Vestibular Syndrome and tinnitus in the risk group, without audiometric alterations.
Conclusion:
The use of oral contraceptives can provoke functional alterations in the inner ear, specially tinnitus and Irritative Peripheral Vestibular Syndrome in the risk group; but auditory threshold alterations were not evident.

01:22Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.

01:30Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
