Genetic incompatibility between the couple, does it exist?

It is estimated that about 20% of reproductive problems are genetic or chromosomal type. That is why today genetic testing is an essential part of the fertility study in couples who come to our clinic looking for descendants.
For the diagnosis of fertility problems there is a set of genetic studies very useful in the assistance of couples with reproductive desire. Tests such as the karyotype in both partners, microdeletion of the Y chromosome in the male or the molecular study of fragile X syndrome in women are usually required tests to determine a possible genetic basis of fertility problems in couples.

Selection of egg donors at Instituto Bernabeu

Currently, oocyte donation is probably the most demanded technique in fertility centers, mainly due to the increase of maternal age. Voluntary participation of donors is essential, but donors must be evaluated carefully in order to avoid unsatisfactory results (do not forget that the ultimate goal is the birth of a healthy child without prejudice to the donor or the recipient couple).
In a recent study carried out in our center and presented at the Congress of the British Fertility Society, the leading causes of rejection in our program were evaluated in 560 potential egg donors. […]

Array-CGH: Discovering the miracles of the embryo. Comprehensive Chromosome Screening (CCS)

New technologies are making remarkable progress in the diagnosis of fertility. The latest development that has been incorporated into the range of diagnostic techniques is called array-CGH.
This new genetic test allows us to analyze our cells’ DNA to limits that years ago we would have considered pure science fiction.
The human genome is made up of 46 chromosomes: 23 from the father and 23 from the mother. All of our organism’s genetic information is stored in these chromosomes. The excess or defect of any chromosome region may be responsible for certain diseases or fertility problems, such as implantation failure or recurrent miscarriages. […]

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.


Egg donation explained simply

For 21 years, egg donation has been a treatment that Instituto Bernabeu offers to women who need it, which has made it a European reference point for egg donation.

It is the reproductive technique with the highest pregnancy rates, over 60% per cycle. At IB, the overall pregnancy rate after three cycles of treatment is over 90%. […]

Azoospermia in the IVF lab

Azoospermia is defined as the absence of sperm in the ejaculate, which is generally classified as either obstructive or secretory. In obstructive azoospermia, the sperm cells cannot complete their journey from the testicle to the urethra through the seminal tract; however, the sperm cells are produced in the testicle (spermatogenesis). […]

The karyotype

All our genetic information is encoded in DNA. DNA is found in the nucleus of every cell of our body as part of the structures called chromosomes. The analysis of these chromosomes is called a karyotype. […]

Spermiogramme and Advanced Semen Studies (FISH AND TUNEL)

A seminogramme or spermiogramme is one of the basic studies performed on men to determine the sperm quality. Sperm is analysed from both a macroscopic and microscopic viewpoint. The most relevant parameters of the study are threefold:
–          Sperm count
–          Sperm motility
–          Sperm morphology

Instituto Bernabeu Egg donors receive special care

A surprising number of patients require the support of assisted reproduction techniques in order to become parents with egg donation treatments playing a major role. These patients choose the professionalism of Instituto Bernabeu to achieve this goal. […]
