Leydig Cells

Which cell secretes inhibin and androgen-binding protein? 

Sertoli cells
– Supporting (sustentacular) cells
– Extend from basement membrane  to lumen

– Tight junctions join adjacent Sertoli cells

– Secrete inhibin

– Secrete androgen-binding protein
• Blood-testis barrier
• Hormone that inhibits FSH secretion
• Binds testosterone to keep concentration high
