IGD is associated with a normal sense of smell (normosmic IGD) in approximately 40% of affected individuals and an impaired sense of smell (Kallmann syndrome) in approximately 60%. IGD can first become apparent in infancy, adolescence, or adulthood. Infant boys with congenital IGD often have micropenis and cryptorchidism. Adolescents and adults with IGD have clinical evidence of hypogonadism and incomplete sexual maturation on physical examination. Adult males with IGD tend to have prepubertal testicular volume (i.e., &lt;4 mL), absence of secondary sexual features (e.g., facial and axillary hair growth, deepening of the voice), decreased muscle mass, diminished libido, erectile dysfunction, and infertility. Adult females have little or no breast development and primary amenorrhea. Although skeletal maturation is delayed, the rate of linear growth is usually normal except for the absence of a distinct pubertal growth spurt." /><meta name="robots" content="index,nofollow,noarchive" />

IGD is associated with a normal sense of smell (normosmic IGD) in approximately 40% of affected individuals and an impaired sense of smell (Kallmann syndrome) in approximately 60%. IGD can first become apparent in infancy, adolescence, or adulthood. Infant boys with congenital IGD often have micropenis and cryptorchidism. Adolescents and adults with IGD have clinical evidence of hypogonadism and incomplete sexual maturation on physical examination. Adult males with IGD tend to have prepubertal testicular volume (i.e., &lt;4 mL), absence of secondary sexual features (e.g., facial and axillary hair growth, deepening of the voice), decreased muscle mass, diminished libido, erectile dysfunction, and infertility. Adult females have little or no breast development and primary amenorrhea. Although skeletal maturation is delayed, the rate of linear growth is usually normal except for the absence of a distinct pubertal growth spurt. [from <a title="GeneReviews" href="https://www.ncbi.nlm.nih.gov/books/NBK1116" class="defSource" target="_blank">GeneReviews</a>]</div><div class="spaceAbove"><strong>Full text of <i>GeneReview</i> (by section):</strong><br /><a class="medgenPMinfo" href="/books/NBK1334#kms.Summary" target="NBK1334">Summary</a>  |  <a class="medgenPMinfo" href="/books/NBK1334#kms.GeneReview_Scope" target="NBK1334">GeneReview Scope</a>  |  <a class="medgenPMinfo" href="/books/NBK1334#kms.Diagnosis" target="NBK1334">Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1334#kms.Clinical_Characteristics" target="NBK1334">Clinical Characteristics</a>  |  <a class="medgenPMinfo" href="/books/NBK1334#kms.Genetically_Related_Allelic_Disorder" target="NBK1334">Genetically Related (Allelic) Disorders</a>  |  <a class="medgenPMinfo" href="/books/NBK1334#kms.Differential_Diagnosis" target="NBK1334">Differential Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1334#kms.Management" target="NBK1334">Management</a>  |  <a class="medgenPMinfo" href="/books/NBK1334#kms.Genetic_Counseling" target="NBK1334">Genetic Counseling</a>  |  <a class="medgenPMinfo" href="/books/NBK1334#kms.Resources" target="NBK1334">Resources</a>  |  <a class="medgenPMinfo" href="/books/NBK1334#kms.Molecular_Genetics" target="NBK1334">Molecular Genetics</a>  |  <a class="medgenPMinfo" href="/books/NBK1334#kms.Chapter_Notes" target="NBK1334">Chapter Notes</a>  |  <a class="medgenPMinfo" href="/books/NBK1334#kms.References" target="NBK1334">References</a></div><div class="spaceAbove"><strong>Authors:</strong><br />

<div class="portlet_content ln"><div class="mgSection"><strong>From OMIM</strong><br />Congenital idiopathic hypogonadotropic hypogonadism (IHH) is a disorder characterized by absent or incomplete sexual maturation by the age of 18 years, in conjunction with low levels of circulating gonadotropins and testosterone and no other abnormalities of the hypothalamic-pituitary axis. Idiopathic hypogonadotropic hypogonadism can be caused by an isolated defect in gonadotropin-releasing hormone (GNRH; 152760) release, action, or both. Other associated nonreproductive phenotypes, such as anosmia, cleft palate, and sensorineural hearing loss, occur with variable frequency. In the presence of anosmia, idiopathic hypogonadotropic hypogonadism has been called 'Kallmann syndrome (KS),' whereas in the presence of a normal sense of smell, it has been termed 'normosmic idiopathic hypogonadotropic hypogonadism (nIHH)' (summary by Raivio et al., 2007). Because families have been found to segregate both KS and nIHH, the disorder is here referred to as 'hypogonadotropic hypogonadism with or without anosmia.'&#13;
For information on the autosomal forms of hypogonadotropic hypogonadism with or without anosmia, see 147950.  <a target="_blank" href="http://www.omim.org/entry/308700">http://www.omim.org/entry/308700</a></div><div class="mgSection"><strong>From MedlinePlus Genetics</strong><br />In Kallmann syndrome, the sense of smell is either diminished (hyposmia) or completely absent (anosmia). This feature distinguishes Kallmann syndrome from most other forms of hypogonadotropic hypogonadism, which do not affect the sense of smell. Many people with Kallmann syndrome are not aware that they are unable to detect odors until the impairment is discovered through testing.<br /><br />Kallmann syndrome can have a wide variety of additional signs and symptoms. These include a failure of one kidney to develop (unilateral renal agenesis), abnormalities of bones in the fingers or toes, a cleft lip with or without an opening in the roof of the mouth (a cleft palate), abnormal eye movements, hearing loss, and abnormalities of tooth development. Some affected individuals have a feature called bimanual synkinesis, in which the movements of one hand are mirrored by the other hand. Bimanual synkinesis can make it difficult to do tasks that require the hands to move separately, such as playing a musical instrument.<br /><br />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. These hormones are normally made in a part of the brain called the hypothalamus. Males born with hypogonadotropic hypogonadism often have an unusually small penis (micropenis) and undescended testes (cryptorchidism). At puberty, most affected individuals do not develop secondary sex characteristics, such as the growth of facial hair and deepening of the voice in males, the start of monthly periods (menstruation) and breast development in females, and a growth spurt in both sexes. Without treatment, most affected men and women are unable to have biological children (infertile).<br /><br />Kallmann syndrome is a condition characterized by delayed or absent puberty and an impaired sense of smell.  <a target="_blank" href="https://medlineplus.gov/genetics/condition/kallmann-syndrome">https://medlineplus.gov/genetics/condition/kallmann-syndrome</a></div></div>
