Reproductive biology
Discover in depth the biological processes related to fertilization, embryo implantation and all aspects affecting human reproductive biology.
Embryo implantation, the ultimate test
It’s the miracle of life: fertilization and human reproduction. A meticulous and perfect process that allows two cells to come together and create another that will develop until transforming into a new being.
Ethics and good practice: Let the truth be told
Assisted Human Reproduction is undoubtedly an area with ethical and moral implications. There are common issues that arise with the generation of new embryos when a couple undergoes ART and with transfers of previously frozen […]
Contamination, environmental toxins and fertility
Scientific evidence from the last 15 years shows that without a doubt, environmental toxins before conception and during pregnancy cause long-lasting effects on reproductive health. An example of this is the exposure to mercury, which […]
Using Magnetic Fields to Select Healthy Sperm: MACS (Magnetic Activated Cell Sorting)
It is well known that having the best possible sperm quality is important to the success of assisted reproduction techniques. To achieve this, the lab has to improve sperm quality based on its motility and […]
Towards a Positive Embryo Transfer
At first glance, the embryo transfer seems to be the quickest and simplest step in the In Vitro Fertilisation (IVF) process. However, it is actually the most critical step in the entire treatment. Successfully overcoming […]
Instituto Bernabeu Pregnancy Guarantee programme
“WE’RE NOT TALKING ABOUT STATISTICS, WE ENSURE YOUR PREGNANCY.” Instituto Bernabeu has always been loyal to its patient care philosophy, and is even more so now in these current hard times, by planning and implementing […]
Is it better to use fresh or frozen oocytes in egg donation?
One of the issues that is generating much controversy amongst oocyte donation patients concerns the origin of the eggs. That is, whether or not they have been frozen and which of these two alternatives is […]
Unraveling the mysteries of ICSI (Intracytoplasmic sperm injection)
We’re dedicating this Instituto Bernabeu forum topic to a very common technique used in the human reproduction laboratory: ICSI or Intracytoplasmic sperm injection. We have prepared this explicative video on the topic, in which Dr. […]
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 […]
Blastocyst, advantages of a transfer on day 4 or 5
When we perform an assisted reproduction cycle, we try to optimise the results as much as possible. Currently, the most physiological way of achieving this is with an embryo culture that reaches the blastocyst stage.
