The male reproductive tract expresses a diverse array of adhesion-GPCRs, many in a highly specific and regulated manner. Despite this specificity of expression, little is known about the function of this receptor family in male reproductive physiology. Insights into function are beginning to emerge with the increasing availability of genetically modified mice harbouring mutations in these genes. Gpr64 is the best characterised of the adhesion-GPCRs in the male reproductive system and the phenotype of Gpr64 knock-out mice implicates this receptor in the regulation of fluid absorption in the efferent ducts and proximal epididymis. This chapter summarizes recent data concerning this receptor and other family members in the male reproductive system.
