In-Vitro Fertilization (IVF)

What is In-Vitro Fertilization?

In-Vitro Fertilisation is one of the most common Assisted Reproduction techniques where an egg is fertilised by a spermatozoon in-vitro in the laboratory. The resulting embryo/embryos are then transferred into the patient’s uterus.
The IVF process consists in four phases: ovarian stimulation, oocyte retrieval (egg pick-up), in-vitro fertilisation of the eggs in the lab, and at last the transfer of the embryo/embryos into the womb (transfer).
Over the past few years, great progress has been made in IVF and today it offers very high pregnancy rates as long as it is performed in a qualified centre.
A correct diagnosis, a personalised guidance for each case and the coordination of the process by the medical team are key to success. It is also essential that it is carried out in a laboratory equipped with the most advanced technology for Reproductive Biology, allowing to obtain the most suitable eggs, sperm and embryos to achieve a pregnancy.

Physician of the Year in Assisted Reproduction 2019

Dr. Marisa López-Teijón’s opinion

“We have just published a scientific study where we have observed that patients who monitor their embryos have better pregnancy rates and, furthermore, these increase in direct proportion to the number of times that they connect to be with them. The French Society of Reproduction has selected this research among the best three of this year!! As you know, patients in our centre have continuous access to the images of their embryos in real time through an online application (Embryomobile)”. Read more.

How is performed an In- Vitro Fertilization?

Before starting an IVF cycle, it’s essential to be well informed on the whole process from a medical, biological, legal and psychological point of view. Furthermore, some tests are required for an in-depth understanding of the characteristics of each couple. It is important to focus on each case to guarantee better results.

Is In- Vitro Fertilization a painful treatment?

In Vitro Fertilisation is not a painful treatment. The great majority of patients, when faced with this doubt, agree that the worst anxiety is experienced throughout the different phases of the cycle, especially when the embryos have already been transferred into the uterus and they await the results (the two-week wait). Therefore, before starting the cycle, couples can consult with a specialised psychologist to deal with the situation in the best possible way.
