Proteomic and biochemical studies on cervical-vaginal fluid (CVF) have revealed that it contains several members of the tissue kallikrein-related peptidase (KLK) family. The roles of KLKs in the lower female reproductive system are not fully understood. In this Review, Muytjens and colleagues discuss the putative roles of KLKs in vaginal fluid and how increased understanding of their function could result in new diagnostic and therapeutic modalities.
