Systemic non-testicular illness has major effects on the testis although these have not always been sufficiently recognized. The clinical management of any medical disorder should include careful consideration of the effects of illness and its treatment on male reproductive health (including fertility, androgenic status and sexual function). Men value highly their reproductive health as part of a full life. Consequently its preservation is an essential consideration in medical care and dissatisfaction can be anticipated should the focus on the presenting disease and its treatment neglect the often unstated, but nevertheless deeply felt, men’s expectations that they retain full reproductive functions. This chapter will highlight the impact of systemic, non-testicular disease on testicular function. In a first part, pathophysiological mechanisms for testicular dysfunction are considered, while the second part highlights specific diseases and their treatment by organ system. Sexual dysfunction and testosterone deficiency or its treatment are covered in other chapters (Chaps. 16, 21, 26) while drug effects on testicular function, a field still remarkably understudied, is covered only in connection with specific diseases for which they are prescribed.
