DNA can influence the willingness of reproduction

reproductionAging society and childless families are both becoming a significant issue throughout industrialized countries. The average age at which people decide to have a first child, as well as the number of families that do not to have children at all, is constantly increasing. This trend is mainly associated with sociologic, economic and environmental factors. But as the latest study suggest, human DNA might also have an influence on adult’s willingness of reproduction.

Surprising findings

morning-sickness-reduces-the-risk-of-pregnancy-lossThe research was conducted by University of Oxford and included an investigation of entire human genetic material. It was mainly based on the meta-analysis of already existing studies. As a result, the scientist were able to create an extremely comprehensive database, that hold information about 600,000 individuals. In addition, the researchers took advantage of the experience gathered by 250 institutions from all around the globe. The final outcome of the research was truly impressive. The specialists found a correlation not only between certain parts of DNA and willingness to reproduction, but also between the total number of wanted children.

DNA code

bezpieczna_pozycjaThe study revealed a relationship between 12 areas of human genetic material and exact age, at which the first child is born. There are 24 genes associated with this mechanism and some of them are already related with certain aspects of infertility. However, the scientists are able to predict the age of giving a first a child only in 1% of all cases. Yet still, despite the small amount of collected data and low rate of foreseeability, it is a huge step towards further investigations in the reproduction field. What is more, the specific part of DNA code is also related with sexual development. That is why the gathered data might be equally useful in the examinations of certain sexual development abnormalities.

Impact on fertility

In majority of the cases, the age of both male and female is crucial, when it comes to reproduction. Considering a safety of the unborn child, it is drastically reduced, when one or both of the parents are above 40 years old. Nevertheless, the possible risk of age-related pregnancy disorders may vary greatly. That is why the research might become very effective in terms of predicting the optimal reproduction range of age.
