Gynaecomastia Health Dictionary

A chromosomal abnormality in which a male has 1, or occasionally more, extra X chromosomes in his cells, giving a complement of instead of. The risk of a baby having the condition increases with maternal age. Features of the syndrome vary in severity and may not become apparent until puberty, when gynaecomastia (breast enlargement) occurs and the testes remain small. Affected males are usually infertile (see infertility). They tend to be tall and thin with a female body shape and absence of body hair. Incidence of learning difficulties is higher in people with Klinefelter’s syndrome than in the general population. There is no cure for the disorder, but hormonal treatment can induce secondary sexual characteristics, and mastectomy may be used to treat gynaecomastia.... klinefelter’s syndrome

This drug inhibits pituitary gonadotrophin secretion (see PITUITARY GLAND; GONADOTROPHINS) and is used in the treatment of ENDOMETRIOSIS, MENORRHAGIA and GYNAECOMASTIA. The dose is usually of the order of 100 mg twice daily and side-effects may include nausea, dizziness, ?ushing and skeletal muscle pain. It is mildly androgenic (see ANDROGEN).... danazol

An individual in whom both ovarian (see OVARIES) and testicular (see TESTICLE) tissue is present. Hermaphrodites may have a testis on one side and an ovary on the other; or an ovotestis on one side and an ovary or testis on the other; or there may be an ovotestis on both sides. Both gonads are usually intra-abdominal. The true hermaphrodite usually has a UTERUS and at least one Fallopian tube (see FALLOPIAN TUBES) on the side of the ovary, and on the side of the testis there is usually a VAS DEFERENS. Most true hermaphrodites are raised as males, but external virilisation is not usually complete. Even when signi?cant phallic development is present, HYPOSPADIAS and CRYPTORCHIDISM are common. At puberty, GYNAECOMASTIA develops and MENSTRUATION is common, as ovarian function is usually more nearly normal than testicular function. The condition is rare. A more common condition is pseudohermaphroditism: these are individuals who possess the gonads of only one sex but whose external genitalia may be ambiguous. The cause is a hormonal imbalance and can usually be corrected by hormone treatment.... hermaphrodite

A condition characterised by underactivity of the testes (see TESTICLE) or OVARIES – the gonads. The condition may be caused by a genetically based disorder resulting in an abnormally functioning gonad (primary hypogonadism) or by a malfunctioning PITUITARY GLAND that fails to produce an adequate amount of gonadotrophin hormone (see GONADOTROPHINS) – secondary hypogonadism. Those affected may fail to develop adequately the secondary characteristics of their sex: males will have delayed puberty, erectile impotence and infertility and also develop GYNAECOMASTIA; females also have delayed puberty, infertility, and sometimes HIRSUTISM.... hypogonadism

An imidazole (see IMIDAZOLES) antifungal drug available for both oral and topical use. Better absorbed orally than other imidazoles, it also has an anti-androgen e?ect which may give rise to GYNAECOMASTIA and IMPOTENCE in men. In view of its potential hepatotoxicity it should not be given orally for trivial infections, but reserved instead for SYSTEMIC fungal infections (see FUNGAL AND YEAST INFECTIONS).... ketoconazole

The original syndrome described by Klinefelter consisted of GYNAECOMASTIA, testicular ATROPHY and INFERTILITY. Intelligence was unimpaired. Patients have been described who have associated mental defects and striking tallness of stature, but the only constant feature of the syndrome is testicular atrophy with resulting azoospermia and infertility.

The atrophy of the testis is the result of ?brosis, which begins to appear in childhood and progresses until all the seminiferous tubules are replaced by ?brous tissue. Gynaecomastia, mental retardation and eunuchoidism (see EUNUCH; loss of male secondary sexual characteristics – small penis, loss of body hair and a high-pitched voice) may be present. Most patients with Klinefelter’s syndrome have 47 chromosomes instead of the normal 46. The extra chromosome is an X chromosome, so that the sex chromosome constitution is XXY instead of XY. Klinefelter’s syndrome is one of the most common chromosome abnormalities and occurs in 1 in 300 of the male population. Patients with this syndrome show that the Y chromosome is strongly sex-determining: thus, a patient who has an XXY chromosome constitution may have the appearance of a normal male, with infertility the only incapacity, while the loss of a Y chromosome leads to the development of a bodily form which is essentially feminine (see TURNER’S SYNDROME).... klinefelter’s syndrome

Rare, but increasing in most countries. Three main types: teratomas, seminomas and lymphomas. The latter affect older men.

Symptoms. A hard usually painless mass in the scrotum can give rise to gynaecomastia – abnormal enlargement of the male breasts.

Of possible value. Alternatives: – Abundant herb teas – Cornsilk, Red Clover, Violet leaves.

An H2-receptor antagonist used as an ulcer-healing drug. Cimetidine promotes the healing of gastric and duodenal ulcers (see peptic ulcer) and reduces the symptoms of oesophagitis. Side effects include dizziness, fatigue, and rashes. More rarely, the drug causes impotence and gynaecomastia.... cimetidine

A synthetic form of the female sex hormone oestrogen, occasionally used to treat prostate cancer (see prostate, cancer of) and, in postmenopausal women only, breast cancer. Common side effects include nausea, oedema, and breast enlargement (gynaecomastia) in men.... diethylstilbestrol

A noncancerous tumour of the pituitary gland that causes overproduction of prolactin. In women, this may result in galactorrhoea, amenorrhoea, or infertility. In men, it may cause impotence and gynaecomastia. In either sex, it may cause headaches, diabetes insipidus, and, if the tumour presses on the optic nerves, loss of the outer visual field. Diagnosis is made from blood tests and CT scanning or MRI of the brain. Treatment may involve removal of the tumour, radiotherapy, or giving the drug bromocriptine.... prolactinoma

(cyproterone acetate) n. a steroid drug that inhibits the effects of male sex hormones (see anti-androgen). It is used to treat hypersexuality disorders and advanced prostate cancer in men; combined with ethinylestradiol as co-cyprindiol, it is used to treat acne and hirsutism in women. Common side-effects include tiredness, loss of strength, inhibition of sperm formation, infertility, and breast enlargement (gynaecomastia). Because of a risk of liver damage, liver function tests should be carried out before and during treatment.... cyproterone

Disorders affecting the breast that are mostly minor and respond readily to treatment. The most important causes of problems are infection, such as mastitis, tumours, and hormonal changes. Breast cysts, fibroadenomas, other noncancerous tumours, or, more rarely, breast cancer may occur. Breast pain and tenderness is common just before menstruation or when a woman is taking hormones. Before menstruation, breasts may become bigger and lumpy. Such lumps shrink when menstruation is over. Hormonal disorders may, rarely, cause galactorrhoea (abnormal milk production). In men, gynaecomastia may result from hormonal disturbance or treatment with certain drugs.... breast, disorders of the

Severe impairment of liver function that develops suddenly or at the final stages of a chronic liver disease. Because the liver breaks down toxins in the blood, liver failure causes the levels of the toxins to rise, affecting the functioning of other organs, particularly the brain. Liver failure may be acute or chronic. Symptoms of acute liver failure develop rapidly and include impaired memory, agitation, and confusion, followed by drowsiness. The functioning of other organs may become impaired, and the condition may lead to coma and death. Features of chronic liver failure develop much more gradually and include jaundice, itching, easy bruising and bleeding, a swollen abdomen due to accumulated fluid, red palms and, in males, gynaecomastia (enlarged breasts) and shrunken testes. Chronic liver failure may suddenly deteriorate into acute liver failure.

Acute liver failure requires urgent hospital care.

Although no treatment can repair damage that has already occurred in acute and chronic liver failure, certain measures, such as prescribing diuretic drugs to reduce abdominal swelling, may be taken to reduce the severity of symptoms.

Consumption of alcohol should cease in all cases.

The prognoses for sufferers of chronic liver failure vary depending on the cause, but some people survive for many years.

For acute liver failure, a liver transplant is necessary to increase the chances of survival.... liver failure
