Summary
Corticotropin-releasing hormone (CRH) regulates the stress response and is found in reproductive tissues. Its role in pregnancy and postpartum mood disorders warrants further investigation.
Area of Science:
- Neuroendocrinology
- Reproductive Biology
Background:
- Corticotropin-releasing hormone (CRH) is a key regulator of the hypothalamic-pituitary-adrenal axis.
- CRH is a 41 amino acid peptide synthesized in the hypothalamus.
- The CRH system includes ligands, receptors (CRH-R1, CRH-R2), and a binding protein (CRHbp).
Purpose of the Study:
- To explore the role of CRH beyond its function in the hypothalamic-pituitary-adrenal axis.
- To investigate the presence and function of CRH in female reproductive tissues.
- To understand CRH's involvement in pregnancy, parturition, and postpartum mood disorders.
Main Methods:
- Literature review and synthesis of existing research on CRH.
- Analysis of CRH gene location and hormone family components.
- Examination of CRH's physiological roles in the endometrium, placenta, and ovary.
Main Results:
- CRH is present in the uterus, placenta, and ovary, influencing reproduction.
- Placental CRH is linked to pregnancy physiology, complications (preeclampsia, preterm labor), and labor onset.
- Elevated unbound placental CRH may cause hypercortisolism in late pregnancy, potentially leading to postpartum depression.
Conclusions:
- CRH plays significant roles in female reproductive functions and pregnancy.
- Dysregulation of CRH, particularly placental CRH, is associated with pregnancy complications and postpartum mood changes.
- Further research is needed to fully elucidate CRH's impact on reproductive health and mental well-being.

01:19Cushing Syndrome II: Pathophysiology
Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
01:37Hypothalamic-Pituitary Axis
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.
01:30Hormonal 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...

01:26Cushing Syndrome I: Introduction
Cushing syndrome refers to the collection of clinical manifestations that arise when tissues are exposed to excessive amounts of cortisol or cortisol-like medications over an extended period. Cortisol, a glucocorticoid produced by the adrenal cortex, regulates metabolism, immune responses, and the body’s adaptation to stress. When its concentration remains chronically elevated, these physiological pathways become dysregulated, resulting in the characteristic features of the syndrome.Exogenous...
01:19Regulation of Hormone Secretion
Regulation of hormone secretion is a finely tuned orchestration driven by various types of stimuli, encompassing neural, humoral, and hormonal signals. Environmental cues instigate neural stimuli, where action potentials traverse nerve fibers to reach their designated targets. An illustrative scenario is the body's response to stress, wherein the sympathetic nervous system releases epinephrine from the adrenal glands, inducing the well-known 'fight or flight' reaction.

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.
