It is a genetic condition that some males are born with. In this condition, the male is born with an extra X chromosome, which can happen due to random genetic error after conception, which is called meiotic nondisjunction of chromosomes. It can cause low testosterone production, facial and body hair, and reduced muscle mass. Such males have little to no sperm production, which can lead to infertility. Its treatments include fertility treatments or testosterone replacement.
