Italians vote in emotional fertility referendum

ROME (Reuters) - Italians began voting in an emotionally charged four-part referendum on fertility treatment and embryo research on Sunday that will test the influence of the Catholic Church and newly elected Pope Benedict. 

As two days of voting that could repeal a restrictive law on assisted procreation began, the big question was whether a minimum turnout of 50 percent of eligible voters would be reached. If not, the referendums would be null and void.
