Genetics

What is Preimplantation Genetic Diagnosis (PGD)? Is PGD indicated in all patients?

Preimplantation genetic diagnosis (PGD) is a very useful tool in Assisted Reproduction for the genetic selection of embryos prior to their transfer to the maternal uterus. It allows the selection of healthy embryos for a large number of diseases and alterations, thus avoiding the transmission of hereditary diseases and the transfer of embryos that would […]

Genetics in premature ovarian failure and menopause

Oocytes are the female gametes, cells that, upon being fertilised by the sperm, will produce an embryo. In humans, the number of oocytes that females have throughout their lives is not unlimited; they are born instead with a limited number. These oocytes gradually run out in each menstruation until their supply becomes completely exhausted at menopause.

It is said that women suffer from premature ovarian failure when menstruation ceases because the oocyte supply has become exhausted at an earlier age than the age when the natural decline of ovarian function occurs (at 50, approximately). In cases where oocytes are still produced in women suffering from premature ovarian failure, they do not respond satisfactorily to the hormones responsible for their development and maturation.

Premature ovarian failure may have important consequences for women:

Obviously, in their fertility: These women cannot conceive naturally and require assisted reproduction techniques in order to bear offspring. These patients also have a high risk that their oocytes will not respond to the In Vitro Fertilisation cycle, thus putting the success of the treatment in danger.On the other hand, the absence of female hormones due to low ovarian activity has serious consequences for health, mainly in cases of cardiovascular disease and osteoporosis.

Criteria for embryo classification

Embryos develop from the moment they are fertilised up until transfer to the mother’s uterus and this development process is assessed by embryologists. The embryos that have evolved correctly and are in the best condition are selected for transfer and/or cryopreservation.

Types of embryos

At Instituto Bernabeu, we categorise embryos in accordance the Association for the Study of Reproductive […]

New expanded GCT. Screening of more than 2500 genetic diseases

We have the latest technology to study and avoid the
main hereditary diseases

Preconceptional genetic studies (also called carrier studies) aim to prevent the birth of a child with recessive diseases. Recessive genetic diseases behave in such a way that individuals can be either completely healthy, carriers or affected. Affected individuals are sick and manifest the disease. […]

IBgen RIF: An Instituto Bernabeu test makes determining the origin of recurrent pregnancy loss and embryo implantation failure possible

IBgen RIF analyses the
variants in genes associated with thrombotic risk, immunological factors and
endometrial receptivity and it improves patient prognosis

This achievement emanates from over four years of intense research work. IBGen RIF, a new test that has been developed by Instituto Bernabeu, highlights the causes of implantation failure and recurrent pregnancy loss when the underlying reasons for […]

Artificial ova and spermatozoa generated using stem cells

Research into and publications about the use of stem
cells to generate artificial gametes
cells has increased significantly over the last few years.

The idea of obtaining ova and spermatozoa – highly complex and specialist cells – using a cell obtained from an adult human being is both appealing and worrying. Patients who are unable to generate their […]

A father’s age and its impact on the health of his children

Anyone who works in the field of fertility puts a great deal of time and effort into working out how to improve pregnancy rates. However, significantly less time is spent thinking about the period that follows gestation or the birth of a healthy child. It’s time to ask ourselves if helping to build healthy and happy families […]
