SUMMARY

The discussion centers on the impossibility of oocyte division occurring without sperm contribution. Participants clarify that transferring nuclear material from one oocyte to another does not equate to artificial fertilization, as sperm is essential for creating an embryo. The genetic contribution of sperm is emphasized as critical, with claims that it influences embryonic development beyond mere genetic material. The conversation highlights misconceptions about reproduction and the necessity of male genetic input.

PREREQUISITES
  • Understanding of oocyte biology and development
  • Knowledge of fertilization processes in mammals
  • Familiarity with genetic material roles in embryogenesis
  • Awareness of reproductive terminology, including "artificial fertilization"
NEXT STEPS
  • Research the role of sperm in embryonic development
  • Study the process of oocyte maturation and fertilization
  • Explore the implications of genetic material contributions in reproduction
  • Investigate current scientific findings on maternal-fetal cell transfer
USEFUL FOR

This discussion is beneficial for biologists, reproductive health specialists, and anyone interested in the mechanisms of fertilization and embryonic development.

If two oocytes are considered, does taking the nuclear material of one and transferring to the other's nucleus start the division of it ?

That happens with oogonia. During development the primordial germ cells form and become oogonia through mitosis (by millions), then they can become primary oocytes.

Thanks. But this process cannot be considered as an artificial fecondation ?
 
fecondation=fertilization.

It is not artificial fertilization. Correct. What @Fervent Freyja defined above is normal reproduction.
I believe you are asking: under the microscope, can one take the nucleus (nuclear mterial) from one oocyte and insert it into another oocyte. Then expect the oocyte (now 2n) to undergo normal cell division to create an embryo? i.e., artificial fertilization.

I do not know.

Absolutely not. What you are asking about would imply that males aren't needed, that's impossible, and a harmful notion. You need a sperm for fertilization to create an embryo. The genetic material from the sperm actually contributes far more than half to the embryo, and also contributes further in ways that the genetic material in the oocyte does not; of course, mainstream would like people to believe differently. There is even evidence that my body could still be harboring and using my Husbands genetic material in different locations, even my brain, years after pregnancy.
