Where Does Spermatogenesis Occur?

Spermatogenesis takes place in the seminiferous tubules inside the testes. Stem cells are located at the outer edge of the tube, and the cells undergo a process to produce viable spermatozoa for reproduction.

Spermatogenesis is a three-phase process that turns stem cells into spermatozoa. The cells undergo spermatocytogenesis, meiosis and spermiogenesis. During spermatocytogenesis, or mitosis, cells divide to produce cells for differentiation. In meiosis, chromosomes in the stem cells are reduced to amount present in mature sperm. The sphere-shaped spermatids change into elongated spermatozoa during spermiogenesis. After these process are complete, the spermatozoa is released into the opening of the seminiferous tubules.
