Gonadal hormones are those hormones that are actually released from the gonads (ex. estrogen, testosterone). Gonadotropins are hormones that CAUSE the release of gonadal hormones, gonadotropins are released from the anterior pituitary gland(tropin means "releasing" so gonadotropin is a gonad hormone releasing hormone) an example of this would be FSH-- follicle stimulating hormone.

Tricuspid regurgitation?

DefinitionTricuspid regurgitation is a disorder in which the heart's tricuspid valve does not close properly, causing blood to flow backward (leak) into the right upper heart chamber (atrium) when the right lower heart chamber (ventricle) contracts.Alternative NamesTricuspid insufficiencyCauses, incidence, and risk factorsThe tricuspid valve separates the right lower heart chamber (the right ventricle) from the right upper heart chamber (right atrium).The most common cause of tricuspid regurgitation is swelling of the right ventricle. Such swelling may be a complication of any disorder that causes failure of the right ventricle.Tricuspid regurgitation may also be caused by or made worse by valve disease on the left side of the heart such as mitral regugitation and mitral stenosis.Other diseases can directly affect the tricuspid valve. The most common of these is rheumatic fever, which is a complication of untreated strep throat infections.Tricuspid regurgitation may be found in those with a type of congenital heart disease called Ebstein's anomaly.Other infrequent causes of tricuspid regurgitation include:Carcinoid tumors, which release a hormone that damages the valveMarfan syndromeInjuryRheumatoid arthritisRadiation therapyAnother important risk factor for tricuspid regurgitation is use of the diet medications called "Fen-Phen" (phentermine and fenfluramine) or dexfenfluramine.SymptomsTricuspid regurgitation may not cause any symptoms if the patient does not have pulmonary hypertension. If pulmonary hypertension and moderate to severe tricuspid regurgitation exist together, the following symptoms may result:Active pulsing in the neck veinsDecreased urine outputFatigue, tirednessGeneral swellingSwelling of the abdomenSwelling of the feet and anklesWeaknessSigns and testsThe health care provider may detect abnormalities when when gently pressing with the hand (palpating) on your chest. The doctor may also feel a pulse over your liver. The physical exam may reveal liver and spleen swelling.Listening to the heart with a stethoscope shows a murmur or abnormal sounds.There may be signs of fluid collection in the abdomen.An ECG or echocardiogram may show swelling of the right side of the heart. Doppler echocardiography or right-sided cardiac catheterization are used to measure blood pressures inside the heart and lungs.TreatmentTreatment may not be needed if there are few or no symptoms. Hospitalization may be required for diagnosis and treatment of severe symptoms.Swelling may be managed by medications (diuretics) that help remove fluids from the body.Underlying disorders should be identified and treated. Some people may be able to have surgery to repair or replace the tricuspid valve. When surgical treatment is done it is usually done as part of another procedure, most commonly mitral valve repair for mitral regurgitation.Expectations (prognosis)Treatment of any underlying conditions, especially high blood pressure in the lungs and swelling of the right lower heart chamber, may correct the disorder. Surgical valve repair or replacement usually provides a cure. However, persons with severe tricuspid regurgitation that cannot be corrected may have a poor prognosis.ComplicationsWorsening of heart failureEndocarditisCirrhosisWeight lossLoss of appetiteCalling your health care providerCall your health care provider if symptoms of tricuspid regurgitation are present.PreventionPrompt treatment of disorders that can cause valve disease reduces your risk of tricuspid regurgitation. Treat strep infections promptly to prevent rheumatic fever.Any invasive procedure, including dental work and cleaning, can introduce bacteria into your bloodstream. The bacteria can infect a damaged mitral valve, causing endocarditis. Always tell your health care provider and dentist if you have a history of heart valve disease or congenital heart disease before treatment. Taking antibiotics before dental or other invasive procedures may decrease your risk of endocarditis.ReferencesKarchmer AW. Infectious endocarditis. In: Libby P, Bonow RO, Mann DL, Zipes DP, eds.

Gonadotropin inhibitors and hypothalamic pituitarial gonadal axis?

The hypothalamic-pituitary-gonadal axis (also HPG axis) is referring to the effects of the hypothalamus, pituitary gland, and gonads as if these individual endocrine glands were a single entity as a whole. Because these glands often behave in cooperation, physiologists and endocrinologists find it convenient and descriptive to speak of them as a single system.The hypothalamic-pituitary-gonadal axis is a critical part in the development and regulation of a number of the body's systems, such as the reproductive, and immune systems. Fluctuations in the hormones cause changes in the hormones produced by each gland and have various widespread and local effects on the body. This axis controls development, reproduction, and aging in animals. The hypothalamus produces gonadotropin-releasing hormone (GnRH). The anterior portion of the pituitary gland produces luteinizing hormone (LH) and follicle-stimulating hormone (FSH), and the gonads produce estrogen and testosterone.

Is GnRH a steroid hormone?

No, GnRH or gonadotropin releasing hormone is not a steroid, but rather a peptide (type of protein) hormone.

What is the hormone gonadotropin-releasing hormone?

It is produced by Hypothalamus.It stimulates secretion of FSH and LH by Pitutory.

What does gonadotropin releasing hormone do?

Gonadotropin-releasing hormone causes the pituitary gland in the brain to make and secrete the hormones luteinizing hormone (LH) and follicle-stimulating hormone (FSH). In men, these hormones cause the testicles to make testosterone. In women, they cause the ovaries to make estrogen and progesterone.

What is the hormone assayed in home pregnancy tests?

The hormone is called hCG or human chorionic gonadotropin. It is also called "human growth hormone."

Which hormone is tested in the majority of pregnancy tests?

hCG, or human chorionic gonadotropin, is the hormone measured by pregnancy tests.

What is the embryonic hormone detected with pregnancy tests called?

The pregnancy hormone detected by pregnancy tests is called human chorionic gonadotropin (hCG). This hormone is produced by the developing placenta shortly after implantation of the fertilized egg in the uterus.

What hormone is secreted by the developing embryo?

Human chorionic gonadotropin (hCG) is the hormone secreted by the developing embryo after implantation in the uterus. It is detected in the blood and urine and is commonly used as a marker for pregnancy testing.
