New examination aimed at testing couples with recurrent implantation failure

Instituto Bernabeu focusses on providing personalised solutions, particularly in cases of patients with a difficult reproductive prognosis (low ovarian reserve and recurrent implantation failure (RIF)).
Carrying out a number of empirical tests and treatments has, on occasions, been put forward as an option in the case of patients suffering from recurrent implantation failure. The latter have proven to be of questionable efficacy and the former have proven to be of limited or no use.
One of the proposed strategies for patients with recurrent implantation failure (RIF) that is providing many of these cases with solutions, is IVF (in vitro fertilisation) with elective freezing and biopsies on all embryos so that the frozen embryos can later be transferred during a natural cycle. In other words, without any hormone treatment.
It is possible to recreate the conditions under which transfer takes place during treatment of this kind by carrying out a mock cycle and evaluating a series of parameters that can influence transfer success. […]

What information does a FISH procedure on spermatozoa provide us with?

When a fertility analysis in the male partner is limited to a seminogram or spermiogram, we only get a partial view of semen quality. A seminogram only provides us with information on the number and characteristics of sperm in the ejaculate (mobility, morphology…). It does not, however, tell us anything about other aspects such as sperm DNA integrity […]

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. […]
