[tri-med] Re: GINA~ tri children and reproduction

i think i know what you are saying but there still the change he could be
sterile too. i've looked and i've not found a full 8 out there. i was told
at salt lake there thay miscarriage or are born still. and the doctors that
i've talked to have not see or heard of a full 8 . if there was it would be
1%..or not happen.. i would love to find out though.. and i know that there
is always that change but i've not found or heard of one being born or
living.. .but thanks for telling me again on sperm and Taylor could have
kids. gina son taylor triosmy 8 mosaic.
