SUMMARY

Oogenesis and spermatogenesis are both arrested until the onset of puberty in humans. Oogenesis halts at the diplotene stage of Prophase I, with primary oocytes remaining in this state from birth until puberty. In contrast, spermatogenesis is arrested at the primary spermatocyte stage. The secondary oocytes are further arrested at the metaphase II stage until fertilization occurs.

PREREQUISITES
  • Understanding of meiosis stages, specifically Prophase I and metaphase II.
  • Knowledge of human reproductive biology.
  • Familiarity with oogenesis and spermatogenesis processes.
  • Basic concepts of gametogenesis in mammals.
NEXT STEPS
  • Research the stages of meiosis in detail, focusing on Prophase I and metaphase II.
  • Study the hormonal changes that trigger puberty and their effects on gametogenesis.
  • Explore the differences between male and female gametogenesis in humans.
  • Investigate the implications of arrested development in oocytes and spermatocytes on fertility.
USEFUL FOR

Students of biology, educators in reproductive health, and anyone interested in human developmental biology will benefit from this discussion.

Hey PF! Have two questions about Oogenesis and Spermatogenesis! In human beings when is oogenesis and spermatogenesis arrested until the onset of puberty? I believe it is at Prophase I and at Primary Spermatocytes, but is this correct? Any input would be great!


Thanks PF!

Thank you for your help! Then does spermatogenesis arrest at spermatogonia until the onset of puberty?
 
i made a mistake in my original post... the 1˚ spermatocyte actually does arrest. I'm not sure when.
 
Is this homework?
 
No big deal Tdod appreciate your help and no it is not; I need to understand the cycle and I don't yet. When I read about it the material only speaks of the arrest occurring at meiosis I it doesn't talk about prophase I

spermatocytes never gets arrested.

primary oocytes arrest at diplotene stage of prophaseI till the female reach puberty. (remember oocyte porduction starts at the time of birth in females).
secondary oocytes are also arrested at the metaphaseII stage till the process of fertilisation take place.
