How harmful and dangerous is paternity later?

Earlier, scientists believed that later paternity has a negative impact on the health of the unborn child. In particular, there was information that approximately every year of life adds to the body of the baby two additional gene mutations.

Recent studies have refuted information that later paternity contributes to the accumulation and further transfer of harmful mutations from generation to generation. To this conclusion, scientists came after a detailed study of the data of several million fathers who lived in Europe from the 17th to the 19th century.

This global study could prove that later paternity does not have a harmful effect on the health of the population as a whole.

There is an opinion among specialists that in many developed countries the population stopped. This is due to the fact that most of the children survive to adulthood, and natural selection is later, impossible.

But this opinion does not agree Ruben Arslan is a German psychologist. Together with other specialists, they conducted a study, the results of which showed that many harmful mutations independently disappear from the population, which means that natural selection continues.

Scientists have carefully studied the church books with records of the birth and death of Europeans of the past centuries. In particular, information was studied in Sweden, Germany, and also in the province of Quebec. After that, the data were compared with modern medical statistics.

The studies obtained before gave information in favor of the fact that each year of the future father on the eve of conception adds to the future child about two harmful mutations.

But a group of specialists led by Arslan was able to show that these mutations do not go further than practical ones. This is due to the fact that children born as a result of late paternity have about 5% fewer children.

The immediate cause of such fertility data is the fact that the presence of additional harmful mutations at the gene level can somewhat complicate the process of conception. So, the number of children born as a result of this will be less.

At the same time, some changes that occur over time are also important. In particular, it was noted that men at this time began to have the first child, but at the same time the average age of future fathers( in comparison with the 17th and 18th centuries) was less.
