IB research: “Ovarian induction in egg donors: Corifollitropin alfa versus urinary FSH”
In last years corifollitropin alfa (ElonvaTM) has been added to the treatments available to induce ovulation. It is especially designed to work much longer than conventional FSH, so that one single injection of Elonva can …
In the last years, on the way to single embryo transfer (SET), preimplantation genetic screening (PGS) using array technology to test embryo aneuploidy of all chromosomes in the blastocyst stage, is becoming the technique of …
Blastocyst biopsy for Comprehensive Chromosomal Screening (CCS) treatments can be addressed through different strategies. When biopsy on D+5 is performed, fresh transfer on day 6 is possible. There is also the option of freezing the …
IB Research on the Embryo Vitrification Model: optimizing the equilibration time.
Vitrification techniques are commonly used in In vitro fertilization (IVF) laboratories. The vitrification process includes a first step of embryo equilibration. This step never exceeds 15 minutes because cryoprotectans can produce embryo damage. The aim …
IB Research: CCS as a means of achieving pregnancy in women who are polymorphism carriers.
Developments in Comprehensive Chromosome Screening (CCS) which provides information on the chromosomal make-up of embryos, have meant that we are able to determine which embryos have chromosome abnormalities and study possible factors affecting those abnormalities.
IB Research: avoiding sexually transmitted diseases in egg donors.
Assuring the best quality and health guarantees of donated gametes for our egg receptor patients has led us to take into account other aspects. As well as the usual tests for egg donor candidates (karyotyping, screening for cystic fibrosis, fragile X …
International Conference: pharmacogenetics and ovarian stimulation
Dr Belén Lledó participated as a speaker in the ‘European Fertility Meeting: Strategies to improve IVF success rate’ which took place on the 10th December in Rome. The Director of Instituto Bernabeu Biotech gave a conference …
New IB research: Communication between sperm and the egg during fertilisation
Female gametes (also known as eggs) are covered by two layers. The first of these is the zona pellucida (ZP) and the second is a layer of granulosa cells. Numerous pieces of research carried out …
A presentation on continued research on work previously awarded a prize was given in the VIII edition of the congress organised by the Spanish Association for the Study of Biology and Human Reproduction held in San Sebastian, …
Social and economic changes have led to motherhood being postponed and, as a result, fertility issues in couples have increased. Prognosis is poorer in older patients when it comes to IVF treatment. Amongst other things, …
