As a result of a number of different factors – essentially social and economic ones – including medical progress (availability and widespread use of contraception), there is a growing demographic trend in the Western world towards delaying when a woman tries for her first child. This translates into a number of different fertility issues that are caused […]
Gamete donation plays a crucial role for a considerable number of patients willing to start a family and seeking the help of assisted reproduction techniques. These patients place their trust in the professionalism of Instituto Bernabeu in order to select the safest and most appropriate donor for them.
Gamete donation is a generous gesture that […]
Research into and publications about the use of stem
cells to generate artificial gametes
cells has increased significantly over the last few years.
The idea of obtaining ova and spermatozoa – highly complex and specialist cells – using a cell obtained from an adult human being is both appealing and worrying. Patients who are unable to generate their […]
Dr Ángela Llaneza is incredibly passionate about her work and loves having a job that truly motivates her, day in, day out. She discovered her interest in medicine just a year or two before she had to choose what to study at university. Whilst she does have relatives who are doctors, she had not really shown […]
Pregnancy losses (miscarriages) usually happen as a result of factors in the foetus or in the mother. However, in 50% of cases, the pregnancy losses that happen during the first trimester of pregnancy are caused by chromosomal abnormalities in the embryo and the number of cases are higher number in women of an advanced age. Abnormalities can be […]

In vitro fertilisationis a procedure that is carried out in an embryology laboratory with the aim of obtaining embryos using female gametes (ova) and male gametes (spermatozoa). The ova and spermatozoa can be retrieved from the patients (the patients’ own gametes) or from female and male donors (donated gametes).
There are many different ways of obtaining embryos which facilitate a […]
Embryo collapse refers to the contractions that are observed in the blastocyst and which have a connection to appropriate embryo development.
Following a number of physical phenomena, there is a build up of liquid in the cavity which ends up forming what we know as the blastocoel. A progressive accumulation of liquid leads to an increase in […]
Anti-müllerian hormone (AMH) is used in reproductive medicine as an ovarian reserve marker. This hormone is detected using a simple blood analysis and, in conjunction with a follicle count ultrasound scan on the ovaries, it helps us to predict a patient’s response to stimulation. This is mainly true when patients have a limited prognosis.
In any case, despite how […]
The miracle of conception involves an intimate union between the ova and spermatozoon, appropriate evolution of the fertilised embryo and, furthermore, an ideal environment inside the uterus so that implantation can take place. Whilst this process might seem simple, it is much more complex than we might think, particularly in human beings. Only 30% of our conceptions end in […]
