Reproductive sequelae of diabetes in male patients.

Diabetes mellitus (DM) is an increasingly prevalent public health concern. A recent study projected the number of people worldwide with DM to increase from 171 million in 2000 to 366 million in 2030. Although DM is a systemic disease that often leads to end-organ dysfunction of multiple body systems, the effects of the condition on male fertility are often not fully appreciated. DM is associated with multiple risk factors for reduced male fertility potential, including erectile dysfunction, various manifestations of ejaculatory dysfunction, and hypogonadism.
