Difference between Spermatogenesis and Oogenesis
Characteristics |
Spermatogenesis |
Oogenesis |
Location | Occurs in testes | Occurs inside the ovary |
Number of gametes | The number of gametes produced is 4. | Gametes produced is 1 |
Production rate | The production of sperm is in million every day. | Only one ovum is released once a month. |
Size of gametes | The size of gametes produced is small(Motile). | The size of gametes produced is large(non-motile). |
Timing | The initiation of the process starts at puberty. | Initiation of the process starts before birth. |
Cell division | The division is equal and helps in the formation of four haploid spermatids. | The division of the cell is unequal and helps in the formation of one haploid ovum and two polar bodies. |
DNA replication | DNA replication occurs during the phase before meiosis I. | DNA replication occurs during fetal development, before birth. |
Metabolic rate | It has a high metabolic rate. | It has a low metabolic rate. |
Type of gamete | Produces genetically diverse sperm cells through meiosis and recombination. | Produces genetically identical daughter cells due to the lack of recombination during meiosis |
Difference Between Spermatogenesis And Oogenesis
Spermatogenesis and Oogenesis are the processes in which male and female gametes are formed. Sperm formation is the process of spermatogenesis, whereas oogenesis is the process by which ova is formed. Mainly spermatogenesis and oogenesis differ in their occurrence, procedure, number, and size of gametes produced after gametogenesis. The difference in the procedure is due to the creation of sperm from spermatogonium and the ovum from oogonium.
