#### **Abstract**

Infection is a multifactorial process, which can be induced by a virus, bacterium, or para‐ site. It may cause many diseases, including obesity, cancer, and infertility. In this chapter, we focus our attention on the association of infection and fertility alteration. Numerous studies have suggested that genetic polymorphisms influencing infection are associated with infertility. So we also review the genetic influence on infection and risk of infertility.
