Summary
Menstrual cycle phases impact vestibular test results in healthy women. These hormonal shifts can influence balance and hearing functions, highlighting the importance of cycle timing in audiology assessments.
Area of Science:
- Otolaryngology
- Neuroscience
- Endocrinology
Background:
- Hormonal fluctuations during the menstrual cycle can disrupt fluid balance within the inner ear.
- Such disruptions may lead to temporary balance and hearing disturbances.
Purpose of the Study:
- To compare vestibular test outcomes in young women during premenstrual and postmenstrual phases.
- Investigate the influence of menstrual cycle timing on vestibular function.
Main Methods:
- Prospective clinical study involving 20 women (18-35 years old) without prior vestibular or hearing issues.
- Vestibular tests were conducted within ten days before and after menstruation.
Main Results:
- Statistically significant differences were observed in calibration, saccadic movements, PRPD, and caloric-induced nystagmus between menstrual phases.
- Factors like age, cycle regularity, family history of hearing/dizziness, and premenstrual symptoms (tinnitus, headache, anxiety, etc.) can affect test results.
Conclusions:
- Vestibular test results in healthy women vary significantly when comparing premenstrual and postmenstrual periods.
- Menstrual cycle phase is a relevant factor to consider in vestibular function assessments.

01:15Equilibrium and Balance
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...
01:19The Menstrual Cycle
The menstrual cycle is a recurrent sequence of changes in the uterine endometrium, specifically its functional layer, the stratum functionalis. This cycle prepares the uterus for potential pregnancy. This cycle typically spans 21–35 days, averaging 28 days, and aligns with the ovarian cycle, regulated by fluctuating levels of ovarian hormones, primarily estrogen and progesterone.
The menstrual phase occurs from days 1 to 5 and involves the shedding of the stratum functionalis, as a uterine...

01:29The Vestibular System
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.
01:22Hormonal Regulation of the Menstrual Cycle
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
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.

01:18Menses Phase
The uterine cycle begins with the menstrual phase, which is considered day one of the cycle and typically lasts about five days. This phase is characterized by the degeneration and shedding of the stratum functionalis, the functional layer of the endometrium.
When fertilization does not occur, the corpus luteum deteriorates, causing a significant drop in the levels of estrogen and progesterone in the body. This hormonal decrease triggers the release of prostaglandins, which cause the uterine...

01:30Hormonal Control of the Ovarian Cycle
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
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...
