Molecular Basis of Inherited Reproductive Disorders Study 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.
