Menopause01:28

Menopause

3.4K
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...

Hormonal Regulation of the Menstrual Cycle01:22

Hormonal Regulation of the Menstrual Cycle

1.2K
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...

Urodynamic Studies: Uroflowmetry

2.1K
Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...

Hormonal Regulation01:40

Hormonal Regulation

47.3K
Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

Hormonal Regulation01:33

Hormonal Regulation

35.3K
The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

The Menstrual Cycle01:19

The Menstrual Cycle

2.4K
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...

Summary
This summary is machine-generated.

Menopause may subtly lower vocal pitch, but standard voice metrics like jitter and shimmer show no significant changes. Further research is needed to fully understand menopause

Area of Science:

  • Otolaryngology
  • Women's Health
  • Acoustic Analysis

Background:

  • Voice complaints are common during menopause.
  • The clinical impact of menopause on voice metrics remains unclear.

Purpose of the Study:

  • To identify and quantify voice-related metrics affected by menopause.
  • To assess the clinical relevance of menopausal voice changes.

Main Methods:

  • Comprehensive literature review and meta-analysis.
  • Included cross-sectional studies comparing pre- and post-menopausal women.
  • Analyzed 6 voice metrics: mean fundamental frequency (f0), jitter, shimmer, noise-to-harmonics ratio, and maximum phonation time.

Main Results:

  • Mean fundamental frequency (f0) was significantly lower in post-menopausal women (speech: -0.94 semitones; sustained vowel: -1.18 semitones).
  • These f0 changes are below the just noticeable difference but above the female-male voice distinction threshold.
  • No significant differences were found for jitter, shimmer, noise-to-harmonics ratio, or maximum phonation time.

Conclusions:

  • Menopause may cause subtle decreases in vocal pitch.
  • Standard acoustic measures may not fully capture menopausal voice changes.
  • Further research is needed to understand the complex interplay of factors affecting voice during menopause.
