Question Pregnancy in Turner syndrome

UW mentioned that pregnancy in turner syndrome is possible in majority of cases with oocyte donation.

Is this possible to happen even without the initial hormonal support provided by the Gravian follicle ?

Patients being mosaics for Turner sy can be fertile, even without oocyte donation and hormone replacement.

In the absence of ovaries in Turner synd, probably by hormonal replacement and oocyte donation, but about its risk for the life of the mother and child

I believe that the reason for mosaicism in Turner sy is not high yield. But as I understood, it is a result of the lost of X chromosome in early stages of embriologic development. Partial deletion of the X chromosome can also occur. No Barr body in cells with only 1 X chr

I would like to add 1 more thing to this mosaicism thread- nondisjunction is possible not just in meiosis 1, but in meiosis 2 and mytosis also.
