Embryo Cryopreservation in Delhi

Book an appointment

Cryopreservation is the technique of storing or freezing certain products such as embryos, sperm, and eggs for further IVF or other fertilization techniques.

An embryo is an egg fertilized with sperm, which has multiple cells. During infertility treatment, fertility drugs or hormones are given to the woman to stimulate the egg's development. After a successful maturation embryo can be used for cryopreservation. More embryos may be developed after the retrieval and fertilization of eggs in the laboratory than the required quantity to be transferred into a woman’s womb. If these non-transferred embryos are enough in quantity, they can be stored through the cryopreservation method. These stored embryos may be further transferred when needed. Embryo cryopreservation provides the opportunity for future or additional embryo transfer. It replaces the inconvenience of an extra IVF cycle. Thawing is also a necessary step performed before reusing the stored tissues.

Procedure

Embryos can be preserved after egg retrieval at any phase from day 1 to day 7. However, each embryo is not ideal for cryopreservation like which divides at a slow rate or irregular in other ways. Therefore, embryos with higher quality are more likely to survive than others and show their future development capability after cryopreservation. The process is started by providing hormones or fertility medications to the woman to produce fertile eggs. These eggs are extracted from the ovaries by the doctor for following further steps. One healthy embryo is produced through successful fertilization. Then the embryo can be transferred to the woman’s womb following embryo development. If more than one embryo develops, the doctor can process embryo cryopreservation for future use.

  • During embryo cryopreservation, water is removed from the cells of embryos furthering rapid cooling.
  • Embryos are placed in a cryoprotectant solution than flash cooled at a higher rate through a process of vitrification.
  • For long term storage, embryos are stored in liquid nitrogen at a temperature -320˚F. The embryo can be cryopreserved for up to 10 years.
  • Prior to a frozen embryo transfer cycle, the natural cycle of the woman is closely examined, and the best stage for embryo transfer is ensured by the doctor.
  • Then the normal procedure of embryo transfer will take place. After two weeks of transfer, a pregnancy test will be conducted.
