46,XY testicular dysgenesis syndrome

46,XY testicular dysgenesis syndrome (TDS) is a condition affecting males where the development of the testes during fetal life is abnormal. This disruption can lead to issues such as undescended testes, reduced sperm production, and a higher risk of testicular cancer. The syndrome is thought to result from environmental or genetic factors that interfere with normal testicular growth and function during fetal development, impacting hormone production and reproductive health later in life. Understanding TDS helps in diagnosing and managing these related conditions early, improving outcomes for affected individuals.
