Summary

Infection and inflammation of the male reproductive tract are complex clinical conditions that can impact reproductive potential through a variety of pathophysiologic mechanisms. In this chapter, we discuss sites of genitourinary (GU) tract infections, infectious organisms, and the numerous ways in which leukocytes may impair male reproduction. Clinically, these processes most likely manifest as leukocytospermia and bacteriospermia.
