Freezing Services

Clinically described as cryopreservation, freezing is a process in which cells or whole tissues are preserved by cooling to sub-zero temperatures (-196 Degree Celsius). When fast frozen in liquid nitrogen, the process is called as (Vitrification). Vitrification is ideal for embryos as it minimizes damage to the cells due to ice crystal formation. Sperm and eggs can also be frozen to achieve a higher chance of success. Cocoon Fertility, with its state-of-the-art facilities, has a well-managed freezing mechanism.

 

Embryo Freezing And Frozen Embryo Transfer Cycle:

In IVF, the ovaries are stimulated to obtain eggs - all of these, if mature, will be fertilized, thus creating embryos in excess of those that can be transferred to the womb at one time. If these (spare) embryos are of sufficiently good quality, they can be frozen and placed in storage for future use. This provides another possibility of pregnancy, without having to go through the process of ovarian stimulation multiple times. These frozen embryos can be replaced in, either a natural cycle (no drugs involved) or in a cycle, in which the lining of the womb is stimulated with hormones (if there are concerns about the endometrial quality). We will be happy to discuss both options with you so that you can make an informed decision.

 

Frozen Eggs:

Egg freezing, as a fertility preservation technique, has been around for many years. With the advent of newer cryopreservation techniques, egg freezing is now a viable option using the Egg Vitrification Egg Storage (EVES) Technique. Frozen eggs extracted from a woman at a younger age will give her a better chance of getting pregnant later in life, rather than with eggs collected when she is older. Over 85% of eggs undergoing the EVES will survive the freeze-thaw process.

 

Frozen Sperm:

Age does not have the same effect on sperm as it has on eggs, which is why men can produce healthy sperm even after the age of 60. Men who need to have a vasectomy, but would like to be able to father a child can opt for sperm freezing. Men who have to undergo cancer treatments can also opt for sperm freezing, as chemotherapy and radiotherapy are known to adversely affect fertility levels.
