  12. According to the testosterone secretion correspondent to lh stimuli, leydig ' s cells could be divided, at least, into two populations : one can secrete testosterone incrementally after lh stimuli, in which star protein synthesis is necessary by the way so - called an acute regulatory pathway ; in another testosterone secretion did not occur at all with or without lh stimuli, if any, it was beyond the sensitive of rhpa technically. so we can conclude that leydig ' cells are heterogeneous in testosterone secretion, one of them is regulated by lh through the acute regulation pathway, another may have some function in testis other than testosterone secretion regulated by lh
