Male erectile dysfunction is caused by decreased testicular function or other testicular disorders. Erectile dysfunction in men may result from diminished testicular function or testicular diseases. It could also be psychogenic erectile dysfunction, primarily caused by various psychological and mental factors such as stress, tension, anxiety, depression, negative sexual experiences, and marital disharmony.
