Testicular dysgenesis syndrome
Testicular dysgenesis syndrome (TDS) is a hypothesized male reproduction-related condition characterized by the presence of symptoms and disorders such as hypospadias, cryptorchidism, poor semen quality, and testicular cancer. The concept was first introduced by N.E. Skakkebæk along with the department of Growth and Reproduction at Copenhagen University in a paper in Human Reproduction.
