| 1. It occurs in testis of human males | 1. It occurs in ovaries of human females. |
| 2. It is continuous process which continues whole life. | 2. It is stopped after a definite age. |
| 3. All the spermatogonia take part in formation of sperm. | 3. Only one follicle cell develops as oocyte while other several follicle cells degenerate in growth phase. |
| 4. Both the maturation division completed in testis. | 4. The 2nd maturation division completes outside the ovary in female. |
| 5. Growth phase is of short duration and involves lesser growth. | 5. Growth phase is of longer duration and involves more growth. |
| 6. Four spermatids are formed from one primary spermatocyte in this process. | 6. Only one ootid and 3 polar bodies are formed from one primary oocyte. |
| 7. Each spermatid is transformed into sperms by metamorphosis. | 7. No metamorphasis occurs during this phase. |
| 8. Ovulation like process does not occur. | 8. Ovulation occurs. |
