Pregnancy after egg freezing

There are times when a woman wants to plan her future with confidence and when she will be ready to give birth to a child.

With the modern rhythms of life now, many times the acquisition of a child is delayed enough with the result that the woman does not have so good or so many eggs.

That is why science gives it the equipment to do the so-called cryopreservation. In other words, to keep her eggs frozen and in a safe bank, so that even later in her life she does not face a fertility problem.

It is a method that more and more women follow.

Another case in which cryopreservation of eggs is required is when there is a problem of oncogenesis in which the woman will undergo chemotherapy and radiation, sometimes resulting in poor function or production of her genetic material.

There are many women who have premature menopause or have a similar history in the family.

It is still possible that the partner has azoospermia, so he must be treated or followed by in vitro fertilization, again with the use of cryopreserved eggs.

Potentially, all women can take advantage of the method, even if it is for a long time.

There are cases where a pregnancy was achieved with cryopreserved eggs even after a decade and their quality remained excellent.

This system has evolved so much that it ensures survival, which reaches almost 100% and in vitro fertilization with cryopreserved eggs is successful, reaching 80-90%.

Success is almost the same as fresh egg pregnancies.

More and more countries are maintaining egg storage banks. More than 1400 such children have already been born in our country.

It is estimated that 1/5 of births in assisted reproduction units come from cryopreserved surplus embryos.

The next question that arises and reasonably concerns, is at what age a woman should keep and guard her eggs, so as not to question in the future, as much as possible, her possibility of fertility.

As the best fertile period, except unexpectedly for a woman, is the age of 25 to 38, this is also the best time to collect eggs.

If a woman is going to face oncological problems, such as breast cancer, which unfortunately nowadays occurs in younger and younger women, then she should discuss the matter with her gynecologist.

Any chemotherapy or radiation will reduce or rather shrink the volume of the ovaries, so the follicles and eggs.

However, after the adventure of her health, the woman must have an Antimillerian hormone test to see how low her egg supply is. A complete ultrasound examination is necessary.

The method helps a woman a lot to make as many extracorporeal efforts as she can and wants using cold-preserved eggs. Especially with the modern method of vitrification and not with the traditional slow freezing.

The benefit of this procedure is that no crystals are created in the fetus, which can mean significant damage to the quality of both the fetus and the child to be conceived.

The egg is stored in special containers of liquid nitrogen, at -196oC until the time of embryo transfer.

Sometimes, however, during thawing, 20-30% of the embryos that do not survive are lost.

The method is ideal when there are even suspicions of chromosomal abnormalities, ie the creation of children with Down syndrome. The older a woman gets, the greater this chance.

The eggs are frozen at a very low temperature, in order not to damage the plasma membrane that protects them like a capsule of each egg.

When the woman requests it, in consultation with her doctor a few days before fertilization and embryo transfer, she asks for the thawing of her egg or eggs and proceeds to fertilization using her partner’s sperm.

The final phase is embryo transfer and the pregnancy rate reaches even 77.3%.
