To distinguish between spermatogenesis and oogenesis is easy since it can be done by their location and the final product. Sperms are small in size, have a distinct tail, which makes it motile. Oogenesis : Spermatogenesis : Definition: Spermatogenesis is the formation of sperms (male gamates). Oogenesis is the formation of eggs in females. Occurrence: It occurs in males, inside testis. Occurs in females, inside the ovary.

Spermatogenesis makes spermatids which develop into sperm cells. Oogenesis. The number of cells made is 2. The process of formation of ovum is known as oogenesis and the production of sperms is what is known as spermatogenesis. Collectively these two distinctively related processes are called as Gametogenesis. So, in other words it can be said that gametogenesis is of two types namely Spermatogenesis and Oogenesis. Summary: Difference Between Spermatogenesis and Oogenesis is that Spermatogenesis produces mature sperm cells and follows the sequence previously described.

When comparing 47,XXY and 48,XXXY, there is a greater risk for congenetial caused by two non-disjunction events in spermatogenesis, both meosis I and meiosis II. This would be caused by two non-disjunction events during oogenesis. Spermatogenesis.

All stages of spermatogenesis occur inside the testis of a male, whereas the stages of oogenesis occur inside the ovaries expect for the last stage (occurs in the oviduct). The key difference between spermatogenesis and oogenesis is that spermatogenesis is the formation of sperms (male gametes) while oogenesis is the formation of eggs (female gametes). Both spermatogenesis and oogenesis are commonly referred to as gametogenesis . Gametogenesis is the series of mitotic and meiotic divisions occurring in the gonads, to form gametes. Spermatogenesis and oogenesis are the two most important processes in life. To distinguish between spermatogenesis and oogenesis is easy since it can be done by their location and the final product. Sperms are small in size, have a distinct tail, which makes it motile.
