In mammals, it occurs in the seminiferous tubules of the male testes. Spermatogenesis is initiated in the male testis with the beginning of puberty. This comprises the entire development of the spermatogonia (former primordial germ cells) up to sperm cells. The gonadal cords that are solid up till then in the juvenile testis develop a lumen (opening) with the start of puberty. They then gradually transform themselves into spermatic canals that eventually reach a length of roughly 50-60 cm.
They are termed convoluted seminiferous tubules and are so numerous and thin that in an adult male testicle their collective length can be 300 to 350 meters.
