The link between thrombophilia and recurrent implantation failure

The percentage of pregnancies achieved following assisted reproduction treatment has progressively increased over the years but we still have a long way to go before we achieve optimum results. This is why alternative treatment options that have not already been attempted are taken into account when several courses of treatment have not given a positive result.

It has been […]

Embryonic development: the embryo on day 1 (D1)

When an oocyte is in an optimum state of maturation, ovulation takes place. This is known as day 0 of development (D0) and fertilisation by a competent spermatozoon must take place during this period.

When the oocyte is fertilised, it is then known as a zygote and
we are now on D1 of development. Certain characteristics and essential
structures need […]

Embryo fragmentation

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. […]

The importance of embryo nutrition in achieving a successful cycle of in vitro fertilisation (IVF): metabolomics

One of the main limitations of assisted reproduction techniques are its embryo implantation failure rates. The implantation rate is the embryo’s ability to implant in the mother’s uterus. In other words, not all embryos are able to give rise to a pregnancy. Some have a greater chance of doing so than others. If it were possible to select embryos with the greatest ability to implant, it would be possible to improve assisted reproduction technique success rates. […]

Is there hope for me following fertilisation failure after ICSI?

In vitro fertilisation treatment (IVF) techniques consist of fertilising oocytes with spermatozoa in a laboratory. They are held under conditions that are similar to their natural environment and, a few days later, the best embryo is selected and placed in the woman’s uterus where it remains until it implants. From this point on, monitoring procedures are the same as in any other spontaneous or natural pregnancy. […]

Oocyte quality

Oocyte quality is one of the most important of the factors that have an impact on fertility in women. Optimum oocyte quality generally gives rise to embryos with an increased ability to implant in the uterus. […]

Assisted hatching

Assisted hatching is a laboratory technique that consists of making a small hole in the zona pellucida, the membrane surrounding the embryo, in order to make it easier for the embryo to hatch out (something that naturally needs to happen) and implant in the uterus. […]

Antiphospholipid Syndrome: What is it? How does it affect pregnancy?

Antibodies are proteins produced by the immune system of our organism to combat possible infections of viral or bacterial origin. In some diseases, the immune system produces antibodies that, erroneously, attack the tissues of our own body. The result of this attack is the appearance of what are known as autoimmune diseases. […]

10 things you should know if you want to freeze your eggs

1 . Does it hurt?
Egg Retrieval is painless. It is carried out by means of a simple vaginal procedure, and the patient is lightly sedated.
2. What’s the right age for preserving my eggs?
Whilst there is no minimum nor maximum age, it is advisable to undergo the procedure before 35 years of age in order to obtain a sufficient number of good quality eggs because, from 35 years of age onwards, there tends to be a decrease in both their quantity and quality. […]
