“The times of King Herod have returned. A mysterious epidemic is claiming the lives of male infants. The surviving boys turn into girls or intersex freaks before their mothers' eyes. Girls give birth without conception, and married couples are stricken with infertility...” Sounds like the beginning of a novel by a crazed science fiction writer, doesn’t it? However, this is not fiction, but a realistic reconstruction of the events that could happen if humanity were to catch an infection that has already affected hundreds of thousands of animal species.
