What is the difference between Oogenesis and Spermatogenesis?

Spermatogenesis and Oogenesis are often interchanged with each other because people assume that they are completely the same. Spermatogenesis is the process wherein sperm cells are produced in males. Oogenesis is the production of eggs from the germ cells in females. The process that these two procedures follow may also be a bit different.

They have some similarities too like the fact that the processes will happen inside the gonads. This means that it will be done in women’s ovaries and men’s testes. Both would also need three stages of cell division before the process will be complete. Obviously, the end result of these two processes is different.

Spermatogenesis is the process of formation of male gametes. This process happens in the seminiferous tubules of the testes. Primary spermatocyte divides into secondary spermatocytes, and each secondary spermatocyte divides into two spermatids. The method of spermatogenesis is completed in the testes. Spermatids then mature into sperm to be able to carry out in the process of reproduction. The entire process takes about 74 days to be completed. Oogenesis is the process of formation of female gametes called ovum. The process takes place in the ovaries.

Before birth, the process of oogenesis begins. At puberty, primary oocytes divide to form secondary oocytes and a polar body. Secondary oocytes divide again and create an ovum and of cold body. Oocyte matures outside the ovaries. The entire process takes days to years to be completed.
