Kallmann syndrome

Kallmann syndrome (KS) is a condition that causes hypogonadotropic hypogonadism (HH) and an impaired sense of smell. HH affects the production of the hormones needed for sexual development. It is present from birth and is due to deficiency of gonadotropin-releasing hormone (GnRH). KS is often diagnosed at puberty due to lack of sexual development Kallmann syndrome is a condition characterized by delayed or absent puberty and an impaired sense of smell.This disorder is a form of hypogonadotropic hypogonadism, which is a condition resulting from a lack of production of certain hormones that direct sexual development Kallmann syndrome combines an impaired sense of smell with a hormonal disorder that delays or prevents puberty. The hormonal disorder is due to underdevelopment of specific neurons, or nerves, in the brain that signal the hypothalamus. Without these neurons, the hypothalamus cannot properly stimulate the production and release of certain hormones. Kallmann syndrome (KS) is a rare genetic disorder in humans that is defined by a delay/absence of signs of puberty along with an absent/impaired sense of smell. A closely related disorder, normosmic idiopathic hypogonadotropic hypogonadism (nIHH), refers to patients with pubertal failure but with a normal sense of smell Kallmann's syndrome is a genetic condition in which there is a complete or incomplete loss of the sense of smell and severe hypogonadism that is associated with infertility and delayed/absent puberty. Epidemiology of Kallmann Syndrome Most cases of Kallmann's syndrome are inherited by an x-linked pattern, hence more common in men

Kallmann syndrome is a rare sex-related condition that occurs in less than 0.025% of the population. Its occurrence is more common in males than in females. It is an X-linked trait and affects the adrenal glands, which causes a deficiency of important endocrine hormonesthat are needed in order for proper sexual development to occur Kallmannův syndrom je vzácné geneticky podmíněné vrozené onemocnění. Vyskytuje se o něco častěji u mužů než u žen a má vliv zejména na pohlavní dospívání postižených Kallmann syndrome is a rare genetic disorder characterized by hypogonadotropic hypogonadism associated with anosmia or hyposmia.When anosmia is absent, a similar syndrome is referred to as normosmic idiopathic hypogonadotropic hypogonadism Kallmann syndrome, like other HH conditions, is characterized by reproductive features centered around a lack of sexual maturation during the years of puberty. These signs can include a lack of testicular development as determined by testicular volume in men, and a failure to start menstruation (amenorrhoea) in women
