AI Thread Summary
The discussion centers on the process of oocyte manipulation and its implications for fertilization. It clarifies that transferring nuclear material from one oocyte to another does not initiate normal cell division or constitute artificial fertilization. The consensus is that fertilization requires sperm, which plays a crucial role in embryo development beyond merely providing genetic material. The conversation also touches on the idea that the genetic contribution from sperm is significant and that maternal bodies may retain genetic material from previous pregnancies, highlighting the complexity of reproductive biology.

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.

The study provides critical new insights into the African Humid Period, a time between 14,500 and 5,000 years ago when the Sahara desert was a green savanna, rich in water bodies that facilitated human habitation and the spread of pastoralism. Later aridification turned this region into the world's largest desert. Due to the extreme aridity of the region today, DNA preservation is poor, making this pioneering ancient DNA study all the more significant. Genomic analyses reveal that the...
