Spermatogenesis

Sertoli cells

few in number, spaced at regular intervals in the seminiferous epithelium and rest on the basement membrane of the tubules

Sertoli cells

support and nourish the developing gametes

Spermatogonia

located in the basal compartments of both membranes

Spermatogonia

cells appear round and pale, with prominent nucleoli

Primary spermatocytes

larger than the spermatogonia, has nuclei which are more rounded, not ovoid as in spermatogonia.

Secondary spermatocytes

have nuclei one half the size of the primary spermatocytes

Spermatids

_______ are characterized by narrow condensed nuclei and tails that extend into the lumen

Leydig cells

steroid-producing cells that synthesize and secrete androgens, primarily testosterone, under the influence of luteinizing hormone

Leydig cells

located in the interstitial tissue between the seminiferous tubules and are crucial for developing male reproductive structures, maintaining spermatogenesis, and regulating secondary male sexual characteristics.
