Dr Borja Marquès presents a study on the self-repair capacity of embryos that proposes to change the criteria to know if they are suitable to be transferred to the womb in Assisted Reproduction treatments.

Institut Marquès has attended the 36th Congress of the Spanish Society of Gynaecology (SEGO) with 10 communications under the arm. Among them, Dr Borja Marquès López-Teijón’s study Signs of embryo self-repair in the IVF laboratory stands out. This work proposes changing the criteria for determining whether embryos are suitable to be transferred to the womb in In Vitro Fertilisation treatments.

The director of Institut Marquès, Dr Marisa López-Teijón, also participated in this meeting held in Murcia with a conference entitled “Limits and conditioning factors in Assisted Reproduction”.

The other studies that Institut Marquès presented at the SEGO congress dealt with toxic substances and male infertility; Embryomobile and its positive effect on the pregnancy rate; Babypod and musical stimulation; the resting of patients after embryo transfer, the relationship between smoking and semen quality or the persistence of the social taboo regarding infertility and Assisted Reproduction treatments.

Embryo cells work as a team to repair themselves

Dr. Borja Marquès, a gynaecologist specialising in Assisted Reproduction, is the author of the study “Signs of self-repair of embryos in the IVF laboratory”, whose conclusions indicate that embryos possess a self-correction mechanism that was unknown until now. According to this work, embryos that have undergone reverse cleavage (disappearance of some of their cells) or multinucleation (presence of two or more nuclei in some of their cells) can successfully give rise to a normal pregnancy and the birth of a healthy baby.

Thanks to incubators with time-lapse cameras (Embryoscope), in the laboratories of Institut Marquès it has been possible to capture images of embryos with reverse cleavage reabsorbing their own cells and of multinucleated embryos expelling the abnormal cells on the 4th or 5th day of life. To achieve this, the development of more than 20,000 embryos was analysed, from fertilisation until they reached the blastocyst stage.
