28 February, International Rare Disease Day

Currently, preimplantation genetic diagnosis (PGD) conducted by fertility clinics like ProcreaTec reduces the risk of passing on rare diseases by 98% According to the Spanish Federation of Rare Diseases, rare diseases are: Illnesses that have a low incidence rate or occur infrequently within the population. To be considered rare, each specific disease can only affect a limited number of the total population, defined in Europe as less than 1 per 2,000 citizens (EC Regulation on Orphan Medicinal Products). It is … Continue reading 28 February, International Rare Disease Day

Advantages of the EmbryoScope at ProcreaTec

Today we talk to Procreatec’s embryologist Nagore Uriarte about the latest technology used in the ProcreaTec lab. We also look at how this technology has affected the centre’s success rates after almost one year. The EmbryoScope What advantages have you observed through using the embryoscope in your work as an embryologist? As we outlined in several videos and recent news posts, the embryoscope is a cutting-edge incubator. Not only can it be used to continuously monitor embryo culture conditions but, … Continue reading Advantages of the EmbryoScope at ProcreaTec

 What is ERA Test?


This is an innovative test which allow to evaluate the receptivity of a woman’s endometrium. This test increases the possibilities of having a successful embryo transfer in some of our patients. When is the endometrium receptive for embryo implantation? Generally, the best implantation moment happens between days 19 to 21 of a menstrual cycle, this is 5 to 7 days after ovulation and it is called ‘implantation window’. What is the Endometrium Receptivity Array Test? This test consists on the … Continue reading  What is ERA Test?

The EmbryoScope is a state of the art incubator.

It has the novel feature of incorporating time-lapse photography, which means that images of developing embryos are taken 24 hours a day. Moreover, the EmbryoScope captures these pictures at different cross-sections of the embryos providing valuable information on their morphology. Not only are images recorded, but also at any given moment the embryologist can watch the embryo development in real time. Once placed inside the EmbryoScope, the embryos are not taken out until the transfer. With a traditional incubator the … Continue reading The EmbryoScope is a state of the art incubator.

Preimplantation genetic diagnosis (PGD)

Definition of PGD Preimplantation genetic diagnosis, or PGD, is a technique which allows the testing of chromosomic and genetic alterations in embryos. This study technique will determine if the analyzed embryos are or not healthy. In this way, only embryos which are free of alterations will be finally transferred to the patient. How is PGD carried out? Patients who are going to undertake treatment with PGD will go through the process as those not using PGD, that is, an egg … Continue reading Preimplantation genetic diagnosis (PGD)

IVF. What next?

Assisted reproduction treatment is no easy option. The couple or woman may have to undergo a number of disappointing failed attempts. Despite the hopes pinned on the ‘last treatment’, medical experts have a duty to advise and orientate their patients on the most suitable treatment. What should people do if IVF treatment is unsuccessful, and how should they decide whether to use a different technique? IVF (In Vitro Fertilisation) is a laboratory process in which eggs extracted from the affected … Continue reading IVF. What next?

Preimplantation Genetic Diagnosis: an increasingly used technique

It is not a new technique, but it is increasingly improved. In fact, it is a commitment to the future for many professionals of assisted reproduction. For years, fertility doctors know that numerous genetic anomalies and chromosomic alterations cause many cases of implantation failures and recurrent miscarriages. Before having PGD, what we could do in those cases was to keep our fingers crossed, wait for embryos of IVF treatment to be adequate for transfer and wish a healthy baby. Nowadays, … Continue reading Preimplantation Genetic Diagnosis: an increasingly used technique

Three frequently-asked questions about fertility treatment

fertility treatment

In Spain can the sex of the baby be selected? The Spanish law on assisted reproduction (Law 14/2006, dated 26 May, on assisted human reproduction techniques) expressly prohibits sex selection and it is considered to be a serious offence for non-medical purposes. Sex selection is only allowed when it can prevent diseases linked to sex, as indicated in Article 12 of the law: Duly authorised centres can practise preimplantation diagnosis techniques for: a) The detection of serious hereditary diseases, that … Continue reading Three frequently-asked questions about fertility treatment

What is the future of assisted reproduction?

What is the future of assisted reproduction?

As we explained in our last post, industry experts such as David Sable assure us that the future of assisted reproduction lies in discovering as much information as possible about embryos to prevent the transmission of disease and ensure the birth of healthy children. The human genome project represents an important breakthrough for assisted reproduction as it has led to the development of a technique that allows embryos to be diagnosed before implantation in the womb. What is preimplantation genetic … Continue reading What is the future of assisted reproduction?

EmbryoGlue and Assisted Hatching


What is it used for? When is it used? EmbryoGlue What is it? EmbryoGlue is a transfer method which has been in use since 2003. It improves implantation success by using a combination of hyaluronic acid and recombinant albumin. Hyaluronic acid is a natural compound found in all human tissue, especially in the uterus. There are high quantities of hyaluronic acid in cells surrounding the egg. What is it used for? A study published following meta-analysis 1 by the Cochrane … Continue reading EmbryoGlue and Assisted Hatching
