Hypothalamic-Pituitary Axis01:37

Hypothalamic-Pituitary Axis

64.6K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

Hormonal Control of the Ovarian Cycle01:30

Hormonal Control of the Ovarian Cycle

6.1K
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...

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...

Hypoglycemia and Glucagon01:15

Hypoglycemia and Glucagon

662
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

Regulation of Food Intake01:30

Regulation of Food Intake

2.0K
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

531
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Summary
This summary is machine-generated.

Stress can cause infertility by disrupting reproductive functions. Functional hypothalamic amenorrhea (FHA), a type of anovulation, results from slowed gonadotropin-releasing hormone pulses, often due to increased stress.

Area of Science:

  • Reproductive Endocrinology
  • Neuroendocrinology

Background:

  • Stress is a potential cause of infertility, impacting various reproductive mechanisms.
  • Functional hypothalamic amenorrhea (FHA) is a recognized consequence of stress-induced reproductive dysfunction.

Purpose of the Study:

  • To summarize current knowledge on the pathogenesis and treatment of stress-induced anovulation (FHA).
  • To provide a clinical guide for understanding and managing FHA.

Main Methods:

  • Review of existing literature on stress, FHA, and reproductive function.
  • Focus on the neuroendocrine mechanisms linking stress to anovulation.

Main Results:

  • FHA involves slowed gonadotropin-releasing hormone (GnRH) pulse frequency, leading to insufficient gonadotropins for folliculogenesis.
  • Increased hypothalamic-pituitary-adrenal (HPA) axis activity is observed in women with FHA, supporting the role of stress.
  • Reproductive suppression severity correlates with individual sensitivity to stressors and their chronicity.

Conclusions:

  • Stress is a significant factor in anovulation and infertility.
  • FHA is a reversible condition characterized by specific neuroendocrine alterations and associated health concerns.
  • Management strategies should consider the interplay of psychogenic and metabolic stressors.
