256: TRANSPLANTING
OVARIES OR TESTICLES
IN REGARD TO
LINEAGE

ɳ Question

What is the status of a child born to a woman who received the
transplant of another woman’s ovaries? Is this child considered the
child of the woman who bore him, having no connection whatsoever
with the donor of the ovaries? Or is he perhaps considered the son of
the original owner of the ovaries and will be forbidden to marry her
daughter or sister, and will inherit her and have to mourn her when
she dies [i.e. could a child have two mothers, a genetic mother as well
as a birth mother]?

I also wish to raise an additional question which is still hypotheti-
cal but which will probably become practical in the near future. What
is the status of a child born to a man who had a testicular transplant
from another man who was killed in a road accident? Does his lin-
eage follow that of the father who sired him, or of the original owner
of the testicles? This relates to forbidden incestuous unions [i.e. to
which ‘father’s’ relatives is he related?] to inheritance, to his lineage as
a Kohen etc.
