Summary
Hypothalamic amenorrhoea (HA) is a common cause of secondary amenorrhoea in women, often triggered by weight loss, exercise, or stress. Understanding its mechanisms and management is vital for fertility and bone health.
Area of Science:
- Reproductive Endocrinology
- Neuroendocrinology
Background:
- Hypothalamic amenorrhoea (HA) constitutes ~30% of secondary amenorrhoea cases in reproductive-aged women.
- It stems from reduced hypothalamic gonadotrophin-releasing hormone (GnRH) secretion, impacting pituitary and gonadal function.
- Functional HA (FHA) arises without structural lesions, often linked to weight loss, intense exercise, or stress.
Purpose of the Study:
- To review the underlying mechanisms of Functional Hypothalamic Amenorrhoea (FHA).
- To summarize the evidence for current clinical management strategies of FHA.
- To discuss emerging therapeutic approaches for FHA.
Main Methods:
- Literature review of studies on hypothalamic amenorrhoea.
- Analysis of clinical management evidence for FHA.
- Synthesis of information on novel FHA therapies.
Main Results:
- FHA is characterized by GnRH deficiency due to lifestyle factors.
- Current management focuses on addressing triggers and restoring reproductive function.
- Emerging therapies aim to improve GnRH pulsatility and downstream signaling.
Conclusions:
- FHA requires timely intervention to prevent long-term effects on fertility and bone health.
- A comprehensive approach addressing physical and psychological factors is essential.
- Further research into novel treatments holds promise for improved patient outcomes.

01:30Hormonal 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...

01:22Hormonal 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...

01:37Hypothalamic-Pituitary Axis
64.7K
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.

01:27Ovarian Cycle
2.9K
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

01:28Menopause
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...

01:15Hypoglycemia and Glucagon
671
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...
