Infertility was a taboo subject until just a few years ago but nowadays it is common practice to turn to a reproductive medicine clinic for help when women are facing issues having children naturally. Instituto Bernabeu wants to give you a few rules of thumb for knowing when the time has come to visit a fertility clinic. […]
The extent of the issue
Obesity is a public health issue both in the general population and in women of childbearing age. Far from improving, the problem has progressively increased over the last few years.
A study published in the journal The Lancet concludes that 13% of the world population has weight
issues. In Spain, there is a growing […]
I’m pregnant. What foods should I avoid eating? – Instituto Bernabeu
During pregnancy, the future mother experiences a number of hormonal changes. It is also very important to be aware of nutritional requirements since they can vary throughout gestation.
It is important to follow a balanced diet that has been adapted to the woman’s new circumstances so that both the […]
The ‘implantation window’ is the name we give to the period of time during which the endometrium in the mother’s uterus is in an appropriate state for embryo implantation to take place.
Implantation is a critical and very precise process during which the embryo makes contact with and penetrates the endometrial tissue in the mother, making gestation possible. This […]
From an immunological point of view, pregnancy is a unique set of circumstances because a woman’s body has to ‘withstand something that is foreign to it’. The mother has to carry the embryo and, in order to do so, her immune system needs to accept co-existence with cells that are at least half foreign in origin. Using a […]
Egg donation has become an option for women who, for whatever reason, can no longer use their own ova. For example, due to poor ovarian reserve, poor oocyte quality and premature menopause.
The process is widely used in Spain. As well as exceeding organ
donations and transplants in number, we also have the largest number of egg
donors in Europe.
Whilst it is not part of the day-to-day routine at reproductive
medicine clinics, it is now increasingly common to have to transport biological
samples (oocytes, semen or embryos) from one clinic to another and even from
one country to another.
There can be several reasons for this such as the following:

The risk of contracting HIV during unprotected sexual intercourse is estimated to be between 0.5 and 1%. For serodiscordant couples (one partner is a carrier), trying for a child naturally can entail an elevated risk of transmission. In cases such as these, assisted reproduction techniques are an excellent choice for getting pregnant without the risk […]
Embryo fragmentation is a phenomenon that takes place in most embryos and its origin is not entirely clear. Some studies would seem to suggest that the fragments come from cell remains that have no nucleus or that they are the result of the decomposition of one or more cells from the embryo itself. The oocyte plays the most important role in fragmentation. Poor oocyte quality can lead to embryos that are highly fragmented. Embryo quality is determined by several characteristics such as the number of cells, their size or if the cell interior has an abnormality of any kind such as granularity or vacuolisation. However, one of the factors that has most impact on embryo quality is the extent of fragmentation. Based on the amount, in percentage, of space that it occupies, fragmentation is categorised into 4 types or degrees. […]
