Spermatogenesis

In multicellular organisms the reproductive process commences with the production of gametes. The gametes are the sex cells that develop inside the gonads, the testes in males and ovary in females. The term gametogenesis includes both spermatogenesis and oogenesis. In vertebrates as well as in higher invertebrates the testis, the site of production of sperm is composite organs, consisting of a number of seminiferous tubules. Sections of the testis would reveal the seminiferous tubules with sperm development in different stages. This means that the spermatogenesis is a continuous process and one can observe the various developmental stages of sperm in a single testis. Spermatogenesis can bc broadly divided into three phases

(1) Multiplication phase,

(2) Growth phase and

(3) Maturation phase
