Embryo freezing is an advanced yet simple procedure to preserve surplus embryos from an IVF or ICSI cycle. If stored properly, cryopreserved embryos can be utilized for a new cycle even after 10 years as freezing renders the embryos ageless.

Embryo freezing is useful for fertility couples who have had a successful IVF birth and would want to have another child a few years later. Freezing surplus embryos also safeguards against the possible failure of an ongoing IVF/ICSI cycle. Furthermore, a frozen embryo transfer (FET) is less taxing in terms of cost, effort and time as it bypasses several steps of a fresh IVF cycle.

we use the Vitrification technique for freezing eggs, sperm and embryos. Vitrification is an ultra-rapid freezing method which eliminates potential damage to the embryo from ice crystals that form inside the embryo’s cells during the conventional slow freezing process. The vitrification process is so fast – nearly 600 times faster — that there is no time for ice crystals to form.

The embryos are cooled to sub-zero temperature (-196°C) using special freezing equipment and safely stored in liquid nitrogen in a sterile, fully-equipped lab. We have been using the fast freeze method for years due to its proven advantages over the traditional freezing technique:

• Ultrafast freezing
• Higher embryo survival rate upon thawing
• Higher embryo implantation rate

• Inappropiate hormonal profile
• Risk of Ovarian Hyper Stimulation Syndrome (OHSS)
• Presence of polyps, hydrosalpinx or hydrometra
• Absence of spermatozoa in the day of the oocyte retrieval
