Future of your eggs and sperms

When the time comes to use the frozen eggs extracted before to conceive in cases where women had gone through the procedure, these cryopreserved eggs are placed in warming solution and assessed. So, the eggs that have survived in the freezing process are fertilized with intracytoplasmic sperm injection (ICSI) resulting to the fertilization of  eggs which will then grow in culture until the embryo(s) are ready to be transferred into the uterus to achieve pregnancy which  actually takes 3-5 days after fertilization. 

Most importantly the procedure proves to be a boon for those undergoing certain medical treatment like radiation or chemotherapy which can harm the fertility. So, if the egg freezing procedure is done before the treatment might enable you to have biological children in the future. 

Why use frozen eggs and not fresh ones’?

3 benefits of using frozen eggs during the IVF process: 

  1. Immediate availability of frozen eggs than the fresh ones’. 
  2. Availability of a variety of donors when frozen eggs are used as compared to fresh ones’. 
  3. Egg freezing in the donor egg treatment cycles results in quicker and more reliable cycles.

 Preparing your uterus for pregnancy

Preparing your uterus for IVF with frozen eggs will begin by taking estrogen orally and also administering progesterone either vaginally or via injections. Once the uterus has appropriately matured, the eggs are then thawed and fertilized with sperm. As a result, embryos are cultured for 3 to 5 days and 1 or 2 embryos is then transferred into your uterus.

How successful is oocyte freezing?

Though the above process registers a sudden decline in the pregnancy from the use of frozen eggs when compared with fresh eggs. This occurred because the pregnancy rate actually depends on the quality of the eggs that are frozen, which is directly related to a patient’s age and the underlying diagnosis. 

3 important factors on which the pregnancy rates depends: 

  1. The freezing technique being used by the hospital
  2. The quality of the eggs
  3. The quality of the sperm

 Do risks exist?
 
Along with having numerous advantages, the use of frozen eggs with IVF technology conveys some unknown risks. A major downside to egg freezing is the lower pregnancy rates when using embryos resulting from frozen eggs. This can be always improved over a period of time as the egg freezing and thawing technology get refined.
