QUESTION
Androgen binding protein (ABP) are secreted from?
OPTIONS
(A) Myoid cells
(B) Interstitial cells
(C) Sertoli cells
(D) Leydig cells
ANSWER
(C) Sertoli cells
EXPLANATION
Sertoli cells secrete androgen-binding protein, which helps maintain high local androgen concentrations in the seminiferous tubules and supports spermatogenesis. Leydig cells, also called interstitial cells, chiefly synthesize testosterone. Peritubular myoid cells contribute structural support and contractility around the tubules. Testosterone production and androgen binding are distinct functions, so the steroid-producing cells are not the answer here.
