Embryo Freezing During IVF or ICSI Cycles
A new technique of embryo freezing was introduced two years ago (VITRIFICATION).
Currently, success rates with embryo freezing and transfer in the next cycle (not
the cycle in which eggs are retrieved) are in the range of 50-60% (10% more than
with fresh embryo transfer). In view of this technology advance, the clinic might
decide to freeze all your embryos and transfer them in the next cycle in the following
situations:)
-
Less eggs and embryos (less than
3 of grade 1)
-
Patients with low AMH and poor
responders (pooling of embryos).
-
History of previous miscarriage.
-
History of previous ectopic pregnancy.
-
More than 20 eggs (hyper-stimulation).
-
Endometrium (uterus lining) thin
or < 7 mm in thickness.
-
History of previous failed IVF
cycles.
-
Any other indication at the discretion
of Dr Jatin.
The decision to freeze all and transfer in the next month might be taken during
your IVF cycle and even as a last minute call it is purely to give you a better
chance and entirely in your own interest. More and more international clinics are
moving towards frozen embryo transfers to:
-
Enhance pregnancy rates.
-
Avoid complications such as ovarian
hyper-stimulation.
-
Lower the risk of early pregnancy
losses (biochemical pregnancies and miscarriages), tubal or ectopic pregnancies.
-
Lower the incidence of preterm
labour and small for gestational age babies.
-
Focus more on implantation from
the point of view of the uterus and its lining (endometrium).
-
Avoid high order multiple pregnancies
(triplets or more).
-
Make treatment simple and relatively
painless.
This revolutionary freezing technique has been mastered by one of our ace embryologists
(Hima Shah) after intensive training at premier IVF institutes in Japan and Italy.
Our clinic also has an active freezing program for eggs (oocytes) especially for
young women who wish to preserve their fertility and have children at a later age.
