Can you imagine that when a failure occurs in the fertilization process, what could be the cause to be able to know with more accuracy how to act to solve the fertility problem of each couple? Well, there is already a method for this. It has been developed by the assisted reproduction center CREA, which has presented this innovative procedure for the study of oocytes during the course 'New tools for the study of gametes in assisted reproduction', directed to and taught by the best experts in the field.

The organization of the medical center has announced that this new tool to diagnose and treat gametes not only improves the effectiveness of assisted reproduction treatments, but also makes them safer.

As explained by Dr. Miguel Ruiz Jorro, co-director of CREA, until now when after fertilization in vitro or sperm microinjection do not obtain success in obtaining any fertilized oocyte, it is impossible to discern at first sight if the cause is due to a dysfunction in the oocyte or sperm. However, this new technique allows us to study the oocytes to find the origin of the failure of fertilization, which makes it possible to know if the solution is to resort to the donation of ovules or semen in order to guide the patient.

Increasingly effective reproductive techniques

In these days taught in the capital of Turia have been able to see also new techniques, safer, effective and simple, to diagnose the sperm DNA fragmentation. This pathology consists in the presence of ruptures or injuries in the genetic material of the spermatozoid due to the oxidation of the membranes, which results in failures in conventional assisted reproduction treatments, and even in occasions in repeat abortions.

One of those techniques is that of Immunomagnetic selection of sperm, also called 'annexation columns', and which CREA has developed together with the gametology expert Vanesa Rawe. This procedure uses magnetic fields to filter the spermatozoids, allowing to select those with complete DNA (without fragmenting), which multiplies the possibilities of originating a healthy embryo, with a better capacity of implantation and of normal evolutionary development. Six out of ten patients with fragmented DNA, get to be parents thanks to this technique.
