Fertility calculations

Mathematics can help on the jumps of fertility. To this end, the researchers of the Department for artificial insemination at the university and Polyclinic “La Fe” and the Polytechnic University of Valencia (UPV), have developed a mathematical model to optimize embryo selection in which the selection of the best embryos a success of fertilization operation to be achieved.

Published in the journal mathemathical and computer modeling research, observed that embryos with reduced viability were spotted faster and it was more helpful and allows a more accurate assessment for successful fertility clinic treatment.

The model assesses the embryo quality using two morphological variables: the number of cells and the symmetry and degree of fragmentation of the embryo. The best embryos are those here who have four cells and the symmetry and fragmentation degree one, ie it is symmetrical cells with less than 10% fragmentation. For these, it is most likely that there is a pregnancy. When artificial insemination but not always such embryos are available. Here, the model can assist the embryologist in selecting those embryos, even if they do not meet the optimal conditions, but can lead to pregnancy.

Wikipedia talks briefly about infertility:

Infertility primarily refers to the biological inability of a person to contribute to conception. Infertility may also refer to the state of a woman who is unable to carry a pregnancy to full term. There are many biological causes of infertility, including some that medical intervention can treat.

Utilizing preimplantation genetic diagnosis is the best way to utilize this method, although there are also other tools for embryo selection these are not as precise and efficient. “With this model, a fast, accurate and efficient statistical analysis is performed, which improves the predictability of common over other methods significantly.”

This model assesses the embryo Quality Index (EQI) obtained score. The index is calculated on the basis of transferred embryos in relation to the aging woman. Observing which case embryology all embryos with the inverted microscope and determine the number of cells and the degree of the embryo. By observing the development, the embryos are selected for transfer into the uterine cavity, which have the best rate of implantation. In retrospect, the EQI of implanted embryos is calculated. The generated index can predict with the woman age the probability of pregnancy.

The research also showed that the probability of pregnancy decreases with age. Contrary to previous studies, however, this development is not linear. This discovery was made ​​in the Health Research Institute “La Fe” by the professional staff of the hospital “La Fe”, Inmaculada Molina, specialist of the Department of In Vitro Fertilization and Antonio Pellicer, director of the Women’s Hospital area of “La Fe”. Of the UPV were involved Ana Debón by the Centre for Quality and Change Management and Suitberto Cabrera of the group wave phenomena.
