Beside the infertility issue, the syndrome causes decreases in bone mass, muscle wasting, decline in cognitive ability and increases the risk of diseases such as diabetes mellitus, cancer and cardiovascular diseases. Most men are diagnosed late when fertility problems arise and some even remain undiagnosed.
