Institut Marquès: Leading reference center in assisted reproduction

In this page you will find information of your interest about technical and practical issues before the first visit.


Even if in colloquial terms infertility and sterility are often used as synonyms, they are different. Sterility is the incapacity to conceive a child. However, infertility is the incapacity to carry the pregnancy long enough to deliver a baby, as it is the case of repeated miscarriages.
When a couple has not been able to conceive after having had unprotected intercourse for a year, they might have infertility problems.


Assisted reproduction can be carried out using different techniques; the most appropriate one will be determined according to the couple’s specific circumstances and problems.

Artificial Insemination

Artificial Insemination consists in an ovulation induction, which involves taking a hormone medication. This encourages the proper ovarian development of 1 to 4 follicles.


In-vitro fertilisation

In-Vitro Fertilization consists in a laboratory oocyte’s fertilization by a spermatozoon, and then, in a in utero transfer of the embryo or embryos (maximum two embryos).


Shared motherhood

That both women participate actively in bringing their child to the world being its ‘biological’ mothers: the first as the genetic mother and the second as the gestational mother.


Embryo adoption

To adopt an embryo means to try to fall pregnant with embryos whose biological parents have not chosen their destination.


Egg vitrification

Is a technique which enables a womans eggs to be frozen so that she can delay and choose when she wishes to become a mother.




Erotic Personal System

It has been proven that a good level of arousal affects semen quality. Therefore, our patients have at their disposal various methods of stimulation.


It’s an incubator that maintains the necessary physiological conditions required by a living embryo during an in vitro process, with a camera that continuously captures images of the embryonic development.


An innovative application developed by Institut Marquès that allows patients to watch the evolution of their embryos, in real time, all day, using their smart phone.


Our IVF laboratory is like a giant uterus: we have replicated the conditions of the uterus in order to improve the embryonic development: same temperature, same light conditions and a nearly totally sterile atmosphere, so that the embryos can “feel at home”.


We have play music because it has been proven that musical vibrations improve the embryo development.

In natural conditions, oocytes and embryos travel through the fallopian tubes into the uterus due to continuous peristaltic movements that move them, surround them with the nutrients they need, and drive them away from their waste metabolites.

These cell movements facilitate the exchange of substances, but embryos in the laboratory remain static in the culture media, and, as a result, the released toxic products -free radicals or ammonium – are stored in the culture medium in which they lie.

That micro vibrations stir the culture media, thus producing a more homogeneous distribution of the nutrients and dispersing toxic products to avoid their accumulation.
