Testicular Androgen Binding Protein (ABP) — A Parameter of Sertoli Cell Secretory Function

Abstract
It has become increasingly evident that many factors affecting spermatogenesis are mediated by the Sertoli cells that carry the developing germ cells in a close embracement during the most critical periods of spermatogenesis. Due to the vital importance of the Sertoli cells, increasing interest has been devoted to finding a biochemical index of Sertoli cell function. Testicular androgen binding protein is so far the only known specific product of Sertoli cells.
