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

Fertility preservation in young cancer patients, an option people know little about

On repeated occasions, we have underlined the fact that doctors have a responsibility to the society they live in.  Part of this responsibility includes properly informing patients of their full options and associated risks when they are diagnosed with a serious illness. A recent study has revealed that most young cancer sufferers whose fertility is put in jeopardy as a result of treatment do not know about fertility preservation, which could enable them to become parents in the future. The … Continue reading Fertility preservation in young cancer patients, an option people know little about

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?

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)

http://d1o7lnqyawgbwf.cloudfront.net/wp-content/uploads/2016/09/DGP-EN.pdf

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)

Diet, fertility and longevity

diet , fertility

Scientists from the Charles Perkins Centre and the ANZAC Research Institute of the University of Sydney have published the results of a study in the journal PNAS (Proceedings of the National Academy of Sciences) which concludes that carbohydrate prolongs life expectancy while protein promotes fertility. These conclusions were reached by adjusting quantities of protein, carbohydrate, fat and energy through 25 types of diet that were given to mice and then analysing the data obtained. Up until now, the widely accepted … Continue reading Diet, fertility and longevity

Does cryopreservation of oocytes affect future embryos?

cryopreservation of oocytes

Cryopreservation of oocytes is a technique that allows women to preserve fertility for the purpose of using these oocytes at a later date or to safeguard fertility due to medical reasons. New York University Fertility Center and New York University School of Medicine conducted a research to determine if long-term cryopreservation of oocytes affects oocyte developmental competence, live-birth rates and blastocyst aneuploidy. In this research, a total of 33 patients cryopreserved their oocytes for various reasons. Only one patient who … Continue reading Does cryopreservation of oocytes affect future embryos?

Does right-sided ovulation favor pregnancy?

ovulation

It appears that it does. Clinics, laboratories and hospitals from Japan and Denmark conducted a research which achieved some interesting results. 1057 cycles of 856 fertile women and 1033 cycles of 258 infertile women were considered. This research aimed to evaluate whether frequency of ovulation and fertility potential of oocytes were different in left and right ovary. Let’s see the results obtained in both fertile and infertile women: Right-sided ovulation occurred more often than left-sided ovulation, although pre-embryo formation from … Continue reading Does right-sided ovulation favor pregnancy?

EmbryoGlue and Assisted Hatching

embryoGlue

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
