Body Composition, Bone Mineral Density, Insulin Sensitivity and Echocardiographic Measurements in Klinefelter Syndrome

August 31, 2007 updated by: University of Aarhus
Klinefelter syndrome (KS) is the most common sex-chromosome disorder with a prevalence of one in 660 men and is a frequent cause of hypogonadism and infertility. It is caused by the presence of extra X-chromosomes, the most common karyotype being 47,XXY. The phenotype is variable, but the most constant finding is small hyalinized testes, hypergonadotrophic hypogonadism, infertility, eunuchoid body proportion, increased height and learning disabilities. Klinefelter syndrome has been associated with increased prevalence of diabetes, osteoporosis and cardiovascular diseases but the pathogenesis is unknown. Accordingly the aim of the study was to investigate measures of body composition, insulin sensitivity, bone mineral density, echocardiography, as well as biochemical markers of endocrine, metabolic and bone function in KS and an age-matched control group.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male
