2. | Germinal cell epithelium includes Sertoli cells. | Germinal cell epithelium does not include Sertoli cells. |
3. | Growth phase in spermatogonia is very short. | Growth phase in Oogenesis is prolonged. |
4. | Sperms can be produced all the times here. | Egg is produced once at a time here. |
5. | Motile sperms or male gametes are produced by the spermatogenesis process. | Non-motile eggs or female gametes are produced by the oogenesis process. |
6. | Formation of polar body does not takes place and spermatogenesis process takes place in the testes. | Formation of polar body takes place and oogenesis process takes place in the ovaries. |
7. | Spermatogenesis process continues till old age. | Oogenesis process stops at 45 years age. |
