The new Instituto Bernabeu Group newsletter is now available, dedicated to our last reserach work accepted at FFER congress 2018.

Instituto Bernabeu has submitted three items of research work to the French Federation of Reproduction Studies (FFER) Congress that will be held in the French city of Lyon between 12^th and 14^th September. The event will bring together over 600 experts from all over the world who will exchange information on the latest updates in fertility and reproduction.

Research performed by Instituto Bernabeu has looked into whether fresh transfer or deferred transfer through cryopreservation followed by defrosting is the best strategy for carrying out pre-implantation genetic diagnosis for aneuploidies (PGT-A).

As a part of our continuous training programme, an intensive theoretical and practical seminar entitled ‘Advanced Workshop in Embryo Biopsy: Techniques and tips for usage’ will take place. The workshop is aimed at reproduction biologists who are specialised in micro-handling techniques.

During assisted reproduction treatment, conventional ovarian stimulation is performed over the first few days of the menstrual cycle. However, recent research shows that it can begin on any day of the menstrual cycle. The advantage is a decrease in the total time before treatment can begin. During the research, the oocyte retrieval results using the two strategies were similar.

Instituto Bernabeu has carried out research work with the aim of understanding if it is possible to predict the success of a cycle of egg donation by analysing two parameters: the number of mature donated oocytes obtained following ovarian stimulation and the quantity that are eventually fertilised.

Based on the positive results obtained, research performed by Instituto Bernabeu in Albacete entertains attempting ovarian stimulation in patients with low oocyte retrieval levels. The strategy is a step taken prior to egg donation.

With the incorporation of genetic techniques, it has been possible to identify a greater number of microorganisms that cannot be analysed with a normal microbiological culture and that make up the vaginal microbiome. A powerful tool to identify the microbiome are the massive sequencing techniques. The analysis of the microbiome is important since, among other things, in the field of reproductive medicine it is possible to detect if there is a microorganism that can facilitate or hinder the implantation of the embryo.

Since one of the parameters that enable us to measure assisted reproductive treatment efficiency is embryo morphology, its research is highly critical.

A study performed in the molecular biology and genetics laboratory at Instituto Bernabeu, IB Biotech, and submitted to the Spanish Fertility Society (SEF) congress has concluded that there is an increased risk of embryo abnormalities in chromosomal segments in young women.
