In what structure does spermatogenesis occur

WebIn human tubules areas of active spermatogenesis are interspersed with resting epithelium. As germ cells mature they move from the basement membrane of the tubule to the tubular lumen. Spermatogonia, the primordial male germ cells that are the precursors of spermatozoa multiply by mitosis throughout adult life. WebWhich hormone(s) is(are) produced by this structure?

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.
