What Does ABP Stand For?

ABP stands for Androgen Binding Protein

Androgen Binding Protein (ABP) is a glycoprotein produced primarily by Sertoli cells in the testes. It plays a crucial role in the male reproductive system by binding to androgens, particularly testosterone, enabling the transport, storage, and availability of these hormones to developing spermatogenic cells. By maintaining high local concentrations of androgens within the seminiferous tubules, ABP is essential for the regulation of spermatogenesis and overall male fertility. Additionally, its function can influence various physiological processes and contribute to the development of male secondary sexual characteristics.
