It is easy to understand from the name that doctors simply can not understand what prevents women on the path to pregnancy. And now scientists from the University of Ferrara, found that half of the victims of female infertility have a virus called HHV-6A, which is spread by bacteria that are very similar to those that cause chickenpox.
