Step 1. Consents: Applicable consents for carrying out such process are obtained from couples/ individuals who are opting for Embryo Freezing.
Step 2. Medical Screening: Screening for individuals/ couples who have provided genetic material used for embryos is carried out to diagnose diseases such as HIV, Hepatitis B & C etc.
Step 3. In Treatment & Freezing: During the process of treatment, the unused embryos are frozen and then stored in tanks of liquid nitrogen. A liquid called a cryo-protectant is added to protect the embryos during freezing
In the standard freezing method, embryos are slowly frozen down to -196 degrees Celsius.
But in ‘Vitrification’is a fast freeze process – the embryo undergoes instantaneous ‘glass-like’ solidification without the damaging formation of ice crystals (which can occur with the standard method of freeze).
One of the above methods are used to freeze the embryos
