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 […]
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. […]
Culture mediums used during embryo development in in vitro fertilisation (IVF) laboratories are crucial to the exit of assisted reproduction treatment of any kind. Culture mediums have the mission of reproducing the physiological conditions inside the female reproductive system as closely as possible, embracing fertilisation up until embryo implantation in the endometrium.
In order for implantation to take place during […]
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 […]
We are not yet fully aware of the exact reasons why sometimes a pregnancy happens and sometimes it does not. The embryo implantation process is an entire set of processes, many of which are unknown.
Based on the fact that the main factors that have an impact on implantation are the embryo and the female uterus, huge progress has been made […]
After ovulation, follicles transform into the corpus luteum or ‘yellow body’. Corpus luteum development depends on the luteinising hormone (LH) surge before ovulation and on the number of receptors for this gonadotropin in the granulosa cells and in the theca cells. Both types of cells go through significant changes in structure and composition and this turns the walls of the corpus […]
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:

Pre-implantation genetic diagnosis(PGD) consists of studying chromosomalabnormalities and genetic abnormalities in the embryo prior to transfer to the mother. Itspurpose is to ensure that children are healthy and to bring thetransmission of a given condition to an end.
Significant progress that has revolutionised this area ofreproductive medicine has been made over the last few years and specificallywith regards to one type […]
The advantages of comprehensive chromosome screening (PGS/PGT-A/CCS) in women of an advanced maternal age
Women currently seek guidance on reproduction at a much older age than they did some years ago. As a result, amongst the women who undergo fertility treatment, there is a significant group of women of an advanced age and their prognosis is poorer. This is a huge challenge for reproduction specialists. […]
