what is major difference between spermatogenesis & oogenesis?
Hi,
Spermatogenesis | Oogenesis |
It is the process by which sperms are formed from the sperm mother cell in males | It is the process by which ovum is formed from the oogonia in females |
After the second meiotic divisions in a single spermatogonium, 4 spermatids are obtained, which undergo maturation to form 4 sperm cells, or spermatozoa | After the second meiotic divisions in the single oogonium, only one ovum and three polar bodies are obtained. |
Spermatogenesis occurs in males from puberty almost until death. | In females, oogenesis starts before birth and occurs until menopause. |
Hope this answers your question,
Cheers!!
