In the process of in vitro fertilization, the stimulation of the ovaries of a female is done so as to produce multiple eggs. This technique is performed in laboratories by creating the special environment and using freezing equipment so that the embryos can be stored in liquid nitrogen for the longer period of time.

What is Embryo Freezing?
Embryo freezing is also known as cryopreservation. This technique refers to a procedural method in which the viable embryos are preserved by keeping them at the cool place at very low temperatures, at -196 degree Celsius. After the process of fertilization is done and acculturation of embryo is performed, then the best embryos out of the group are selected for transfer of embryos. In 50 percent of cases, there are ample amount of embryos to fulfill the requirement of embryo transfer. And hence, these embryos can be frozen for use in future purposes.

Advantages of Embryo Freezing
One of the best advantages of embryo freezing is that thawing of frozen embryos can be done and then these can be transferred in the uterus of women without stimulating ovaries. The cycle of transferring frozen embryos is quite simple. The assessment of the menstrual cycle is done to estimate the uterus lining development in females and at the time of ovulation, the embryo is transferred. In certain cases, the women’s medical history is taken before and the hormonally controlled cycle is warranted. However, one should always consult the clinician before going for any treatment procedure.

Disadvantages of embryo freezing
As per the research history, almost 70% of the frozen embryos are able to survive the thawing purpose. But the success rate varies from individual to individual. It may be possible that even after saving many embryos, none of the embryos survive the thawing process.
