Embryo Pooling Method

What is the embryo pooling process?

The first step in IVF treatment is the development of follicles. For this purpose, enhancer injection called gonadotropin are used daily. After the collection of the eggs, microinjection is performed and embryos are obtained. In the pooling process, the obtained embryos are not transferred, but stored by freezing. The process of obtaining embryos and storing them under appropriate conditions and performing this process more than once is called pooling.

To Whom is Embryo Pooling Applied?

Embryo pooling is a method performed especially in women with low ovarian reserve. First of all, in the IVF treatment process, the injection to enlarge the eggs is started-the eggs are collected-The embryos are obtained after the fertilization process and these embryos are frozen without transfer. The freezing process is done using a special technique called vitrification and is carried out by placing these embryos in liquid nitrogen tanks at -190 degrees.

In what other cases is embryo pooling recommended?

It is especially recommended in elderly women, in the presence of recurrent pregnancy losses, in cases where genetic screening of excess embryos is required. After the embryos are obtained, biopsies of the embryos are made and sent for genetic testing, and especially in women with a low number of embryos, embryos are obtained more than once, biopsied and subjected to genetic testing.

Are Embryos Damaged While Being Stored, Frozen or Thawed?

The probability of damage by rapid freezing and thawing technique called vitrification is very low. It’s almost less than 5%. These embryos, which are labeled and stored in special tanks, can be safely stored for many years.
