This newspaper stay Peng, special correspondent of U.S.A., it splashes womans to be child-bearing peak period, are men like this too? The latest scientific research shows: The man has child-bearing peak period too like woman, very great that the child that the man gives birth to suffers from the possibility of schizophrenia at advanced age. Materials of the expert research nearly 90,000 people of American Columbia University, New York University medical college, Israeli Ministry of Public Health, these people were born in Jerusalem between 1976 and 1964. Expert find 45 year old it suffers from possibility of schizophrenia to be 25 -year-old young the intersection of man and 2 times of child given birth to to 49 -year-old child that man give birth to; Child's ill probability that the man above the age of 50 is given birth to is 3 times of the latter's. This research still reveals, 26.6% of the schizophrenia patients are because older when father bear, seem not to have big relation with mother; The longer the parents time united by marriage is, the lower the child's chance to suffer from schizophrenia is, but this can not offset father's older dangers brought. This discovery has broken people's traditional idea. People think woman make mum advanced age, its child presented physiology and amentia easily in the past, and the man is a bit older become father and have a little effect on child. This result of study has made the new explanation to the reason to cause schizophrenia too. Schizophrenia is the most common spiritual disease, 1% people suffer from schizophrenia in the world, 2,200,000 people suffer from this disease in U.S.A.. In the past, people thought schizophrenia was mainly caused by genetic function and social environmental impact. Why advanced age high that the child that the man gives birth to suffer from the probability of schizophrenia? The scientists have made explanations to this, in fact the root of the trouble lies in sperm's sudden change. When the man becomes large at age, the sperm realizes and regenerates by cell division gradually, each division of sperm, all probably make a mistake in the course of duplicating the chromosome. And the sperm which carry the wrong chromosome may pass this kind of mistake to the future generation after combining with the egg cell. The expert warns, if the man wants to give birth to the child at advanced age, must consider the adverse effect that age may bring.
