1. MICROSCOPIC STRUCTURE OF THE MALE REPRODUCTIVE SYSTEM Testis, excretory genital ducts, accessory genital glands, and penis Spermato- and spermiogenesis Composition of the sperm (ejaculate)

4. Testis Greek - orchis tunica albuginea mediastinum testis septula testis lobuli testis 200 – 250 2-4 seminiferous tubules + interstitial tissue with LEYDIG´s cells scrotum

6. Seminiferous tubule: membrana propria, basal lamina and germinal epithelium

8. adluminal compartment basal

11. Spermatogenesis spematocytogenesis meiosis spermiogenesis

12. Spermiogenesis

13. Tubuli recti Rete testis both are lined with simple flat to columnar epithelium
