About this study

Background: \- During puberty, children begin to develop into adults. Problems with the hormones released during puberty can affect the reproductive system. Some people have low hormone levels that severely delay or prevent puberty. Others start puberty abnormally early. Other people may have a normal puberty but develop reproductive disorders later in life. Researchers want to study people with reproductive disorders to learn more about how these disorders may be inherited. Objectives: \- To learn how reproductive system disorders may be inherited. Eligibility: * People with one of the following problems: * Abnormally early puberty * Abnormally late or no puberty * Normal puberty with hormonal problems that develop later in life * People who have not yet had puberty but have symptoms that indicate low hormone levels. Design: * Participants will provide a blood sample for testing. They will complete a questionnaire about their symptoms. They will also have a scratch-and-sniff test to study any problems with their ability to smell. * Participant medical records will be reviewed. Participants will also provide a family medical history. * Family members of those in the study may be invited to participate. * Treatment will not be provided as part of this study.
