https://en.wikipedia.org/wiki/Spermatogenic
Spermatogenesis is the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testis.This process starts with the mitotic division of the stem cells located close to the basement membrane of the tubules. These cells are called spermatogonial stem cells.The mitotic division of these produces two types of cells.

Isolation of enriched population of spermatogenic cells as well as Sertoli and Leydig cells from testes is one of the crucial steps to address these important issues. Over the years, various approaches have been used to successfully isolate testicular cells. One approach isolates cells using fluorescence-activated cell sorting (FACS) (3-6).
