Health Alert:

Although sporadic cases are the most frequent, families with congenital IHH have been reported with X-linked, autosomal dominant or recessive inheritance. Others have noted that the common comorbidities associated with diabetes, such as obesity and obstructive sleep apnea, may all contribute in similar ways, making it difficult to assess the strength of the independent effect that diabetes has on hypogonadism. Hypogonadotropic hypogonadism HH is characterized by failure of gonadal function secondary to deficient gonadotropin secretion 1.

Side effects of gonadotropin treatment include the inconvenient way of administration, gynecomastia, and the induction of antibodies to hCG, which can impair the response to hCG in secondary hypogonadotropic hypogonadism females in the military future 34 Women may stop fmeales men and women may experience hot flashes, osteoporosis, or anemia; and men may experience breast development. Similarly, the pituitary function can be first evaluated by basal hormonal levels measured by ultrasensitive assays. Substantial variation in clinical expression of the same genetic defect in families of patients with IHH has been observed, with affected members presenting with Kallmann syndrome, normosmic IHH, isolated anosmia, isolated clefting, simple pubertal delay, or even apparent phenotypic normality, suggesting the possibility that Kallmann syndrome and normosmic IHH may take part of a wider spectrum of disease 310 Lynnette Nieman, M.

  • The reversible form of HH should be suspected if testicular volume increases during testosterone administration or in the absence of endocrine therapy.

This type of phenotypic heterogeneity may be ascribed to environmental or epigenetic effects. A second explanation is the coexistence within families of defects in 2 or more different genes that interact functionally, as it has recently been described in a number of families 10 Am J Ment Defic. As our population ages and we become more adept at identifying these common illnesses, it is important to realize that many disease states, and even some medications, may be possible causes of signs and symptoms of secondary hypogonadism. The early presentation of the hypogonadism, manifesting as primary amenorrhea, and the association with nonreproductive phenotypes ogival palate and bone abnormalities contributed to the hypothesis of a congenital defect in this apparently sporadic case of IHH.
