In in vitro fertilisation (IVF) or intra-cytoplasmic sperm injection (ICSI) treatment, fertility drugs are used to stimulate the ovaries to produce more eggs than usual.Patients who undergo IVF may have several eggs collected. The eggs are then fertilized with a sperm and checked for fertilization.Fertilized eggs are called embryos.A patient may have multiple high quality embryos eligible for embryo transfer back to the uterus. A certain number of embryos are chosen for embryo transfer, and the surplus of high quality embryos can be cryopreserved for future use.In an IVF cycle only an appropriate number of embryos are transferred into a woman’s uterus.As a result, patient is left with extra embryos created at the time of ivf treatment.These additional embryos can be frozen (cryopreserved) and stored or may be discarded or donated as per the wish of the patient.Embryo freezing provides a patient with the opportunity to conceive more than once from a single egg recovery cycle.
The procedure of Embryo Freezing or Vitrification
After a fresh embryo transfer, good quality surplus embryos and blastocysts created during IVF or ICSI treatment may be frozen and stored for future use.Embryos can be frozen from Day 2 (four cell stage) to Day 5 (Blastocyst).They are placed in thin plastic straws, sealed at both ends, and labeled with your name and identification number.They are then frozen where the temperature rapidly drops to -150° Celsius.The straws are then placed in goblets, and put into tanks filled with liquid nitrogen, which keeps the temperature at -196° Celsius to suspend their development. Once frozen,they can remain in liquid nitrogen for many years without deterioration before being thawed and,if they survive and subsequently develop well,transferred to the woman’s uterus during a frozen embryo transfer (FET).
Vitrification, a cutting edge technology for cryopreservation (freezing) of embryos and eggs, is available at Al-Manar Fertility & Endoscopy Center in Basrah, Iraq. There IVF laboratory maintains gold standard. All egg retrievals and embryo transfers take place at Al-Manar Fertility & Endoscopy Center.There embryo identification procedure is meticulously performed by an experienced embryologist and they are available at every critical step in embryology process transfer and cryopreservation.
