Visualizing the development of your embryos before transferring it to the mother’s womb improves pregnancy rates in in vitro fertilization cycles (IVF). Researchers at the Institut Marquès have proven that active behavior, such as watching live images of their own embryos developing in an incubator during the five days of blastocyst culture, increases the chances of pregnancy.
“In the field of human reproduction, despite the evidence that infertility by itself and assisted reproduction treatments can generate anxiety and stress, the impact of emotions on pregnancy rates is underestimated,” the authors indicate. The interaction between the psyche and the nervous, endocrine and immune system is already known and this approach has been applied to understand and treat different pathological conditions from a holistic point of view.
In the study of the Institut Marquès, 934 women participated in a cycle of IVF and embryo transfer in fresh for a period of three years (2016-2018). To minimize the variables related to the oocyte and embryonic factor, ovule donation cycles have been included in the study exclusively. All embryos were grown in a time-lapse incubator and mothers were able to connect online to the images of their embryos before transfer.
“We have observed an increase in pregnancy rates as the number of visualizations increases, reaching statistical relevance for the group that exceeded 30 visualizations compared to the other groups. Pregnancy and clinical pregnancy rates by transfer of single blastocyst in fresh were 72.3% in this group,” say the authors. The results have just been presented at different scientific congresses in Europe.
The embryoscope is revolutionizing embryonic medicine. It is an incubator that maintains in vitro the physiological conditions that the embryo requires in vivo with a special peculiarity: it incorporates a camera that continuously captures images of embryonic development. Patients thus have the possibility to watch this first film of life from their home via the internet and follow the evolution as do the embryologists themselves.
