Frequently Asked Questions on IVF

Fertilización In Vitro Fecundación

High Complexity techniques are mainly summarized in traditional In Vitro Fertilization (IVF) and Intracytoplasmic Sperm Injection (ICSI)

These are techniques aimed at carrying out the fertilization of the egg with a sperm. Subgroups of treatments and technologies applied to each one are derived from these two techniques to improve clinical results and favor the development of zygotes.

In IVF, oocytes are obtained by ultrasound-guided needle aspiration of previously stimulated ovarian follicles, vaginally in an operating room and under the effect of sedation, to later go to the IVF laboratory and prepare them for fertilization. The biologist is in charge of preparing both the plates and culture media depending on the technique to be used (IVF or ICSI), as well as its execution.

Once the fertilization of the oocytes has been observed, the development of the zygote is carried out inside an incubator that simulates the fallopian tube in the woman, monitoring all the development from day 1 in the zygote to day 5 or 6 in the blastocyst.

Subsequently, the transfer of the blastocyst(s) is carried out in the operating room with the patient awake, introducing them with a special cannula into the uterus with the help of a vaginal mirror.

These are some of the questions most frequently asked by patients who require In Vitro Fertilization treatment:

In in vitro fertilization we generate better conditions for a natural event to occur that up to now had not been possible.

If we transfer one or two embryos, the possibility of pregnancy is one or two babies, no more

The care will depend on your particular case, not on the fact of coming from an in vitro fertilization cycle.

Preimplantation Genetic Diagnosis is a fairly safe technique where the benefits far outweigh the risks.

It is possible to increase the probability of generating a certain sex, as well as to know it before transferring it

There is a classification technique that offers an effectiveness of 92% for X chromosome (girls) and 81% for Y chromosome (boys).

Rest is not necessary, you can continue your usual activities except for specific contraindications

Vitrified but not transferred embryos are vitrified (frozen) and can be used later without going through the entire process again

From the start of ovarian stimulation to the pregnancy test it will take a month

During ovarian stimulation you may feel slightly swollen or uncomfortable, it is very rarely necessary to suspend it for these reasons.

Generally, all that is needed is a clinical and ultrasound evaluation of the woman, a seminal study of the couple, and blood samples from both.

A testicular biopsy can obtain sperm to fertilize the eggs

No, no greater risk inherent to the technique has been found.
