You can avoid passing hereditary diseases on to your children by taking the GCT (Genetic Compatibility Test)

Our Genetic Compatibility Test (GCT) based on next-generation DNA sequencing analyses over 600 diseases.
For a person with an hereditary disease, eliminating the chance of passing that disease on to their children becomes a desire as well as the very best gift they could give them. Sometimes, parents don’t even know they are carriers of a disease. A person with an hereditary disease will pass it on to his or her children. Sufferers carry a heavy weight upon their shoulders because they are aware that they will pass on health issues to their children and that this will have a negative impact on their quality of life or lead to premature death. In most cases, we are carriers of one recessive disease or another, but our health is not affected by it. However, there is the possibility that we might pass that disease on to our children. […]

Why does Comprehensive Chromosome Screening (PGS/PGT-A/CCS) by array-CGH reduce miscarriage rates?

Miscarriage rates in the general population with no fertility problems range around 15-20%. In other words, one out of every five couples who achieve pregnancy suffers a spontaneous miscarriage, and 5% of these couples suffer it more than once. Even when pregnancy is achieved with the help of assisted reproduction techniques, miscarriage rates do not vary. For this reason, it is important when couples come to our clinic seeking reproductive counselling to perform comprehensive testing and design an adequate protocol for their case to secure the best result, which is a healthy baby at home, minimising the chances of miscarriage. In order to do that, one should know that miscarriages and pregnancy losses are caused by different reasons (uterine problems, immunological problems, and so on), and yet in half the cases there are chromosomal abnormalities in the embryo that prevent pregnancies to progress, hence causing miscarriages. Normal embryos have two copies of each chromosome, one inherited from the father and the other from the mother, and the chromosomal anomalies they may suffer involve a change in the number of copies, producing an imbalance in their genetic load which might block embryo development.

Instituto Bernabeu begins research on a new treatment for patients with poor ovarian response

From January 2016, Instituto Bernabeu will work on a clinical trial (free to participating patients) with the aim of evaluating the efficiency of a line of treatment in patients with poor response to ovarian stimulation.
The research, which has already been approved by the Spanish Drug Agency and has been published in the USA National Health Institute register, involves comparing ovarian response to two different stimulation protocols. One is conventional with drug administration starting at the beginning of the cycle. The other, new procedure carries out stimulation once it has been confirmed that the patient is ovulating. […]

Assisted Reproduction in women who do not have a male partner

In modern society, the increasing demand for assisted reproduction techniques from single women and same-sex couples has become a reality. From the perspective of reproduction, women only need to receive the male gamete (sperm). For years, these couples have solved the problem in ways that have not always been medically or legally safe and have had to face the possibility of infectious diseases and paternity suits.
Today, these inconveniencies are solved in assisted reproduction centres, where procedures that meet their demands and offer them a solid and safe foundation are regularly performed.
Thanks to Assisted Reproduction Techniques (ART), Reproductive Medicine enables us to distinguish the fact of reproduction from the act of intercourse between two people. Several options for motherhood are offered to both single women and […]

Usefulness of Comprehensive Chromosomal Screening (PGS/PGT-A/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. […]

Accumulation of oocytes in patients with a low response.

The number of oocytes retrieved is a key prognostic factor in In Vitro Fertilisation (IVF) treatments. Chances are greater the greater the number of retrieved oocytes is, until the moment when 6 to 8 oocytes have already been retrieved.
For this reason, care of patients with a Low Response should be especially thorough, both as regards the chosen protocol for ovarian stimulation and the processes of oocyte retrieval and management at the laboratory. In these cases, retrieving an extra oocyte may considerably increase the chances of success.
While many of these patients benefit from the implementation of specific stimulation protocols and the use of adjuvant therapies, some of them will be refractive and will yield a very poor response.
The appearance of vitrification as a successful technique to freeze both oocytes and embryos has stirred new expectations in patients with a low response at the possibility of accumulating vitrified oocytes from several stimulation cycles. This way, after performing a number of oocyte collection cycles and once collecting a number between 6 and 8 oocytes has been achieved, the processes of fertilisation begin. In this case, prognosis is more favourable, as patients now have more or less the same number of oocytes as those patients with a normal response. […]

Low ovarian reserve, a challenge with optimistic future in Instituto Bernabeu

The social changes in recent years have been highly beneficial to achieving rights and equalities, although it has also led to a significant increase in maternal age. But nature does not understand social change and the biological clock keeps ticking as usual. There are several consequences of this delay on female fertility and it depends on each woman, but it is a reality that as women age, the ovarian reserve diminishes and the egg quality lowers. […]

Egg Donation, solidarity and life

Solidarity can be carried out in very different areas of life and society: supporting initiatives of NGOs or associations, or dedicating some of our time to community service in our neighbourhood or town or simply carrying out daily routines to improve the lives of those around us. It is basically making a gesture or devoting some of our time to make a little effort towards others. […]

Genetic Health of the Embryo: Science Applied to Life

This is not science fiction, it’s reality. It is reproductive medicine and advanced genetics together to achieve healthy children who are free of diseases. Before, medicine focused on a person’s health. Now thanks to genetics and scientific research we are able to go one step further and take care of the embryo. […]

Why aren’t all embryos obtained from an IVF cycle suitable for freezing?

Today, in In Vitro Fertilization treatments, it is not extraordinary to find ourselves on the day of embryo transfer with a high number of good quality embryos. For a fresh transfer we shall be electing the embryo or embryos that morphologically and kinetically demonstrate greater development and ‘the other’ good quality ones can be cryopreserved. […]
