'''Spermatogenesis''' is the process through which immature sperm cells called [[Spermatogonial stem cells|spermatogonial stem cells]] (which are actually [[Stem cell|stem cells]]) are transformed through a series of different types of cell divisions to produce mature sperm cells called [[Spermatozoa]]. | '''Spermatogenesis''' is the process through which immature sperm cells called [[Spermatogonial stem cells|spermatogonial stem cells]] (which are actually [[Stem cell|stem cells]]) are transformed through a series of different types of cell divisions to produce mature sperm cells called [[Spermatozoa]]. | ||

Spermatogonia (or Spermatogonium singular) are undifferentiated spermatogenic cells that need to be differentiated through the processes of [[Mitosis|mitosis]] and [[Meiosis|meiosis]] before they become mature sperm cells. Spermatogenesis occurs in the [[Seminiferous tubules |seminiferous tubules]] of the testis. Both Spermatogenesis and Oogenesis are forms of Gametogenesis (formation of male and female gametes from primordial germ cells). | |||

[[Testicles]] are constantly producing new sperm in spermatogenesis. The full process takes about 64 days. During spermatogenesis, testicles make several million sperm per day — about 1,500 per second. By the end of a full sperm production cycle, you can regenerate up to 8 billion sperm. | [[Testicles]] are constantly producing new sperm in spermatogenesis. The full process takes about 64 days.

The main difference between spermatogenesis and [[Spermiogenesis|spermiogenesis]] is that spermatogenesis is the formation of sperm cells whereas spermiogenesis is the <u>maturation of the spermatids into sperm cells</u>. Spermatogenesis is the complete process of the production of the sperm cells from the cells of the germinal epithelium of males. | The main difference between spermatogenesis and [[Spermiogenesis|spermiogenesis]] is that spermatogenesis is the formation of sperm cells whereas spermiogenesis is the <u>maturation of the [[Spermatid|spermatids]] into sperm cells</u>.

On the other hand, Spermiogenesis is the final differentiation and maturation process of the spermatids into sperm cells. | ||
