Embryo Vitrification

What is Embryo Vitrification?

Vitrification is an ultra fast freezing technique that allows the preservation of the embryos produced in assisted reproduction treatments.

The vitrification technique allows us to preserve the good quality embryos produced in the reproduction treatments once the fresh transfer has been carried out. Embryos are also vitrified when the patient’s uterus is not ready to receive them, as in cases of ovarian hyperstimulation or when the endometrium is not very receptive.

Successful pregnancy rates with Embryo Vitrification

At Clinica Fertia we analyse the success rates we achieve with the techniques we apply. In the case of embryo vitrification, the success rates resulting from our experience are:

 What does the technique consist of?

The vitrification technique consists of ultra-fast freezing, of the order of -15000ºC per second. To achieve this, the fluid contained in the cells must first be replaced by a special solution called the Culture Medium. In this way we can prevent the formation of crystals that would affect the embryo.
The results of vitrification are measured by survival rates, based on how the embryo withstands the process of both freezing and the subsequent thawing. For this reason, given that high-quality embryos are required, not all the embryos are usually vitrified.

Once vitrified, the embryos are stored in containers of liquid nitrogen, at temperatures close to -196ºC.

Ask us
How long do I have to wait to start treatment?
If the evaluation is successful, treatment can be started immediately.
Treatment can be scheduled for the month that best suits the couple. In the case of egg recipients, the waiting time is usually one or two months.
How many attempts can I make?

In the case of artificial insemination, here at the clinic we recommend a maximum of four attempts, since 90% of pregnancies occur in the first four cycles.
Regarding In-vitro fertilisation or microinjection, our clinic never makes more than four attempts using these techniques.
In the case of egg donation, it is more difficult to establish a limit, this will normally be determined by psychological and also economic factors.

Can you use these techniques when you have already entered menopause?
Yes. Nowadays, it is possible to become a mother after entering menopause, either physiological due to ovarian failure, or after treatment of neoplastic diseases.
In these cases, the reception of eggs from a donor must be used.
What are the biggest concerns of egg or sperm recipient couples?
Anonymity is what worries most couples and, at Clínica Fertia, this is absolutely always guaranteed. Although a patient accepts to undergo the treatment, they do want the upmost discretion.
Another factor that concerns a couple is the health of the donors and the physical resemblance to them.
In our centre, both in the case of sperm donors and egg donors, our goal is to seek that the physical resemblance is as similar as possible to the parents.
Are these treatments expensive?
For a couple with fertility problems to achieve a pregnancy it can cost between 800 and 6,000 euros, if an assisted reproduction technique is used. Although the price not only depends on the technique used, but also on the frequency of its application.
Clínica Fertia is a pioneer in maintaining an honest and transparent policy. Since 2002 we have published the information of the cost of our treatments on our website.
