Genetic compatibility in couples

When faced with fertility issues, many people believe that this is often due to the couple’s incompatibility. The reason behind this inability to fall pregnant is often unknown and quite simply a mystery due to some form of irresolvable  ‘genetic issue’. When faced with such circumstances, we can but give in and accept it and, as with all popular beliefs, there is some truth in it.
It’s estimated that around 20% of reproduction issues are down to genetics. In fact, many of the tests carried out as part of patient fertility analyses in our clinic, aim to determine if there is a genetic issue behind the couple’s difficulties falling pregnant. […]

Can I choose the sex of my embryos when I undergo embryo transfer?

The human genome consists of 46 chromosomes: 23 of these are inherited from our father and the other 23 are inherited from our mother. Our organism’s entire genetic make-up is stored in these chromosomes. The 23 pairs are organised as follows: 22 pairs, known as autosomes, and one pair of sex chromosomes (X and Y) which differentiate the two sexes (XY for males and XX for females).
From a technical point of view, using pre-implantation genetic diagnosis, we have the means of analysing an embryo’s entire chromosomal make-up. This technique, which is known as CCS (Comprehensive Chromosome Screening), means additional or a lack of any chromosomes in the embryo can be detected. Therefore, we can use CCS to analyse the entire make-up of the embryo and determine that there are neither DNA excesses nor deficiencies which will stop the embryo from developing properly. But, if we focus on the sex chromosomes, we can also determine if the analysed embryo has two X chromosomes and will, therefore, be a girl (XX) or one X chromosome and one Y chromosome (XY) and will be a boy.

The Rafael Bernabeu Foundation and its social welfare calling

The Rafael Bernabeu Foundation, the social welfare foundation at Instituto Bernabeu, has been working towards helping to improve health, well-being and financial conditions in society since 2007. Support programmes for patients with financial difficulties, scholarships and long-term support for various NGOs and academic and medical institutions are just some examples of the work which is carried out “as part of our commitment to the people of Alicante.” To the company, “social responsibility is a must.”

The foundation was set up at almost the same time as Instituto Bernabeu in Alicante. Whilst work went on in the reproduction and fertility clinic, the needs of the local population surrounding the medical group as it grew and became more consolidated became clear. It was the company’s closest reality, its closest community, the people who could potentially one day walk past one of the groups newest branches. IB began donating part of its financial resources and this increased as the institution grew. Along with the company’s growth and strength came the decision to provide this giving spirit, which had been active for many years, with a more formal structure. The Rafael Bernabeu Foundation was born in the cold month of January 2007 with the aim of providing different causes and adverse circumstances with warmth and solutions.

“Our patients and everyone in the IB team are participants in this support aimed at the very same society which has enabled us to grow and to which we wish to return the favour,” says the Rafael Bernabeu Foundation. Since it was set up, its work, donations and activities have grown and centred around three core areas: health, training and financial support for NGOs. […]

Comprehensive Chromosomal Screening (CCS): More reliable and less damaging for embryos

The necessary information for an adequate development of human beings is contained in some “books” called genes; they are written in an “ink” called DNA. Our total number of genes is found in the 46 chromosomes that we inherit from our parents, and it should have no excesses or deficiencies, since these could cause serious diseases and malformations, and even put our life in danger.
Human embryos have a high rate of chromosomal alterations, especially in the case of couples with fertility problems, such as recurrent miscarriages and implantation failures. For this reason, when we are in the In Vitro Fertilisation (IVF) laboratory with a couple’s embryos, we already know it is very likely that many of them are chromosomally abnormal.
Only embryos with no excesses or deficiencies in their DNA have the capacity to produce a healthy newborn. Therefore, by identifying and selecting an embryo with a full chromosome count, we manage to guarantee that the embryo has maximum capacity to produce a healthy child. […]

Usefulness of Comprehensive Chromosomal Screening (CCS) in Recurrent Miscarriages

When couples make the decision to have a baby, either by natural means or by resorting to assisted reproduction techniques (ART), one of their main concerns is having a full-term pregnancy and a healthy baby. Miscarriage occurs in about 10-15% of pregnancies and is regarded as a “Recurrent miscarriage” when two or more pregnancies are lost spontaneously.
The cause of “Recurrent miscarriages” may be immunological, hormonal or uterine. Yet, the most common cause is no doubt chromosomal, since it is present in more than 50% of cases. […]

Are PGD, PGS and CCS all one and the same?

Pre-implantation Genetic Diagnosis (PGD) is a combination of techniques carried out on embryos prior to transfer to the womb with the aim of studying possible chromosomal and/or genetic disorders. Its purpose is to ensure healthy offspring and stop disorders from being passed on to children.
The 21st century has witnessed huge steps being made in terms of embryo abnormality analysis. The range of diagnosis options and the reliability of techniques have converted something which was only a pipe-dream a few years ago into a reality. Nowadays, such techniques are routine and Instituto Bernabeu is a worldwide leader in providing its patients with the latest in embryo genetic diagnosis.
This revolution has led to a number of new testing techniques coming to the fore. Most of them are known by their initials and, in many cases, this has turned PGD into mumbo-gumbo for patients who end up getting them mixed up and confused. We would like to use this forum to shed some light on this sea of initials. […]

Genetic approach to embryo implantation failure and repeated miscarriage

Couples that don’t achieve pregnancy after in vitro fertilization treatments and those who lose their pregnancy in early stages require a multidisciplinary approach in order to diagnose and treat their reproductive problem.
From a genetic point of view, these patients are more likely to produce embryos with chromosomal abnormalities. To improve these couples’ pregnancy rates, the preimplantational genetic diagnosis (PGD) can be applied. In these cases, the goal is to select the embryos with the highest capacity of resulting in an ongoing pregnancy thanks to the fact that the PGD allows us to identify the number of chromosomes in the embryo. Only embryos with the correct number of chromosomes can lead to a healthy child, others will arrest in their development or will lead to a miscarriage. […]

Indications of Preimplantation Genetic Diagnosis (PGD)

Preimplantation Genetic Diagnosis (PGD) is a new technique used in Reproductive Medicine and is one of the main sources of innovation and research. PGD allows embryos to be selected from assisted reproduction cycles and tested for certain genetic or chromosomal abnormalitybefore being transferred to the womb.


Advantages of Embryo Donation

One of the options for patients undergoing In Vitro Fertilization (IVF) techniques with remaining embryos, meaning high quality embryos that can be cryopreserved for the future, is to donate these embryos to other couples for reproductive purposes. In most cases, these embryos come from couples that have gone through double donation treatments (egg and sperm), and after achieving their goal of becoming parents, decide to donate their embryos so that other couples can achieve their own.
