How have children

For young women may be better to have children with middle-aged man: a new study shows, it is more likely to give birth to healthy children than in young men with raging hormones.

A large study of the question of how age affects the parents’ risk of developing the child’s problems at birth, found that the greatest danger are those kids whose fathers are not yet twenty years. The children of young fathers to 22% more likely to die in the first four weeks of life, and the chance of dying in the first year they have a 41% higher than those whose fathers of twenty. In addition, they have 17% more likely to be born prematurely and underweight.

Moreover, if a man over forty, the risk of congenital disease in children is not increased.

Age of all mothers who participated in the study ranged from 20 to 29 years to eliminate the influence of maternal age on the results. Results of work published in the medical journal Human Reproduction.

Led the team, Professor Shi Wu Wen of the Research Institute of Health in Ottawa, Canada, said that the findings are of great value. “Although the risk in most individual cases increased slightly, to society as a whole, it is huge, if observed by us indeed increase the risk associated with paternal age.”

Probably, however, that its role is played by social factors.

Fathers of adolescents in most cases, poorer than men over forty, they have less education, they rarely provide their pregnant wives of medical care, which would allow to avoid problems in the child. Allan Pacey, lecturer in andrology at Sheffield University, said: “It’s easy to say that in the case of a young father’s sperm, if they were somehow abnormal.”

“But this was contrary to the data set of studies showing that the DNA of germ cells in men with age increases the number of defects”.

“It is much more convincing explanation is that older men simply have more opportunities to support their pregnant wives, than the young. It seems that older fathers, children begin life in a more favorable launch conditions.”
