Summary
Androgens, like testosterone, influence blood pressure and cardiovascular health. While acute effects may lower vascular tone, long-term androgen action promotes vasoconstriction, atherosclerosis, and hypertension, impacting disease prevalence.
Area of Science:
- Endocrinology
- Cardiovascular Science
- Nephrology
Background:
- Androgens influence sex-specific blood pressure regulation.
- Men exhibit higher risks for hypertension and coronary heart disease than premenopausal women.
- Androgen effects on renal and cardiovascular systems are complex.
Purpose of the Study:
- To review testosterone's actions on the renal and cardiovascular systems.
- To critically analyze the role of androgens in blood pressure regulation.
Main Methods:
- Systematic literature search of PubMed.
- Keywords: 'blood pressure', 'hypertension', 'testosterone', 'androgens'.
- Inclusion of experimental, animal, and clinical studies.
Main Results:
- Acute testosterone administration may decrease vascular tone.
- Long-term androgen exposure promotes vasoconstriction via upregulated thromboxane A2, norepinephrine, angiotensin II, and endothelin-1.
- Androgens induce cardiac hypertrophy, atherosclerosis, vascular remodeling, and stimulate renal prohypertensive processes (e.g., renin-angiotensin-aldosterone system).
- Androgens may promote oxidative stress and influence brain areas regulating blood pressure.
Conclusions:
- Androgen effects on the renal-vascular system are complex and sometimes contradictory.
- Net effects of androgen action include vasoconstriction, atherosclerosis, and renin-angiotensin-aldosterone system stimulation.
- Androgens are implicated in determining blood pressure and cardiovascular disease prevalence.

01:17Hormonal Regulation of Blood Pressure
Endocrinal or hormonal intervention in the cardiovascular system is predominantly exerted by the catecholamines - epinephrine and norepinephrine, as well as a slew of hormones that interact with renal function to modulate blood volume.
Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction while...

01:26Testosterone: Functions and Regulation
The intricate hormonal interplay essential for male reproductive health begins with the release of gonadotropin-releasing hormone (GnRH) by the hypothalamus. This hormone prompts the pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). LH targets the Leydig cells in the testes, stimulating them to produce and release testosterone. In concert with testosterone, FSH acts on the Sertoli cells within the seminiferous tubules to facilitate the release of...
01:18Hypertension and Regulation of Blood Pressure
Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...
01:30Blood Pressure
Blood pressure (BP) is the pressure or force of blood exerted on the artery's walls as it circulates through the body. It is essential for maintaining blood flow throughout the body.
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the diastolic...

01:24Blood Pressure
The movement of blood in a human body, commonly referred to as blood flow, is determined by the volume of blood that traverses a certain section of the bodily system per unit time. It is the rhythmic contraction of the heart's ventricles that primarily instigates this movement. As the ventricles contract, blood is forced into the prominent arteries, which then flow from areas of greater pressure to lower pressure areas. This movement continues into smaller arteries and arterioles and...
01:33Hormonal Regulation
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.
