Explain the function of Leydig cells and Sertoli cells in the development of sperm inside the testes.

Expert Solution

Sertoli Cells

Sertoli cels extend from the basement membrane of germinal epithelium to the lumen of tubule.
Sertoli cells envelope developing germ cells.They support the developing spermatogenic cells.
They nourishes the sperm and help in spermatogenesis.
Phagocytosis of cytoplasm shed by developing spermatogenic cells
They are joined one another by junctional complexes and form the blood testis barrier.This barrier separate germinal epithelium into two compartment , a basal compartment which contain sertoli cells and diploid germ cell precursors and adluminal compartment , which contain the product of meosis.
It help in formation of androgen binding protein, antimullerian hormone etc..

Leydig Cell

Leydig cells are located within loose connective tissue surrounding seminiferous tubule.
Leydig cell produce testosterone , in response to leutinizing hormone released by pituitary gland .
Testosterone is responsible for secondary sexual characteristics and maintenance of germinal epithelium.
They also secrete androstenedione and dehydroepiandrosterone
They increase cholestrol desmolase activity, which help in conversion of cholestrol into pregnenolone
