Embryo freezing


Embryo Freezing - Save a child for future

During a typical IVF or ICSI cycle, many eggs are retrieved from women's ovaries. Also, many sperms are retrieved from the male body too and after the fertilisation process, there are several embryo formations during IVF treatment. The doctors choose the best embryo and transfer it to the uterus of female but even after transferring sometimes the remaining embryos are healthy to be used for subsequent cycles. These remaining embryos are preserved freezing techniques for future use.

With the growth of medical science, new techniques are emerging at a constant rate and making our life more comfortable. Embryo freezing is a good way to preserve your ability to conceive in future. There are mainly two methods to preserve embryo - traditional slow rate method and vitrification. All the best IVF clinic in India use vitrification to preserve sperm, egg, and embryo remained after treatments. A high concentration cryoprotectant is used to solidify the cell in vitrification process for future use. Liquid nitrogen is used to solidify the embryo instantly at - 196A°C. The complete process is carried out in laboratories by experts and the frozen embryo is stored safely in liquid nitrogen to prevent damage.

Benefits of embryo freezing

This method can help you prevent undergoing the complete retrieval process next time if you have healthy embryos in the first cycle. Sometimes, there are enough healthy embryos for more than one cycle and that prevents you from undergoing the complete complex process next time you want to conceive.

Use of frozen embryo

The IVF procedure using frozen embryo is similar to the procedure using fresh embryo. Either the natural cycles of women are monitored using ultrasound or some medications are given to prepare the uterus line for embryo transfer. The medical history and other things will be kept in mind while choosing any of the processes. The frozen embryo is brought to the original state by reversing the vitrification process and then it is transferred in the uterus at a suitable time.

Success rate

The success rate of embryo freezing depends on the chances of survival of frozen embryo. According to records, 70% of frozen embryos survive and after that, the treatment is most of the times successful if the embryo is in good condition. However, the embryos with the best quality are always used in the first cycle and only left embryos which are slightly less good are frozen and therefore the chances of successful conception are less. But if the embryo is of good quality and it survives the freezing process, the chances of conception are nearly equal to simple IVF treatment.

Who should go for embryo freezing?

  • Some couples want to have another baby in future and if any healthy embryo still exists after transfer, fertility specialist store that
  • In some cases, embryo transfer can be postponed due to reasons like severe OHSS or poor endometrium
  • If the women is going for any complex medical treatment and she wants to save her reproductive potential, embryo freezing is helpful
