Why do we continue using fresh donor eggs when doing donor
egg IVF treatment ?
It's now standard practice all over the world to use only
frozen sperm for donor insemination, because we know that fresh sperm carries
the hazards of HIV transmission.
Now, this is true for donor eggs as well, yet we continue
to use fresh eggs from fresh donors. However this is completely unacceptable,
especially when the technology for freezing eggs has become so mature. When eggs are vitrified, the survival rate is
100% in a good clinic with an experienced embryologist, who has the required
Just like we quarantine frozen sperm samples, we should make
sure that the only eggs which are used for donor egg IVF are frozen eggs , to prevent
the inadvertent transmission of HIV/AIDS through IVF.
Not only are frozen eggs far safer, the pregnancy rate
with them is higher. It's much more reliable to use frozen eggs, because we
know how many there are , and we can guarantee that we will be able to use at
last 10 mature eggs for the recipient.
It's also much easier to match the physical traits of the
egg donor and the recipient when we use frozen eggs, because we don't have to
worry about synchronising their cycles.
