Специалисты выяснили, почему мужчинам стоит бояться переливания женской кровиScientists came to an unexpected conclusion.

The procedure of blood transfusion is considered to be one of the most common in medicine.

In the selection of donor blood is considered blood type and RH factor, but the results of a study by Dutch scientists indicate that important gender can be both donor and recipient.
The authors of the Medical centre at Leiden University have studied data on the health 31118 recipients who had undergone a blood transfusion. They found out who was the recipient, and also examined information about three-year survival rate of donors.

It turned out that men who were given blood from women with a history of at least one pregnancy, 13% more likely to die within three years after the procedure than patients of male sex that this blood is not transfused. The authors concluded that males are more preferred donors were donors-male or female, who has never been pregnant. In the risk group consisted of only men under the age of 50 years.

The authors have not yet proposed a scientifically sound explanation that they discovered phenomena, but plan to continue research in this area. They suggest that the pregnancy has caused some changes in the immune system women, and therefore transfusion of their own blood might increase the chance of premature death of the donors. However, why such blood is “bad” only for men younger than 50 years, is not explained.

Many scientists react to the results of skeptical, expressing hope that the criteria for the selection of donors and recipients during blood transfusion to change is still not necessary. At least until that time, until you have obtained evidence that men under 50 years do not should pour the blood of women who have ever been pregnant. They suggested that the impact could have been some other factors.

In earlier studies conducted by other scholars, evidence of this fact had been received on health and life expectancy reshepients not affected not gender or age of the donors.
