While Ms Lorenzin stressed that conscientious objection is respected in Italy, she also said that hospitals can ask regional governments to complete "specific individual services".
Earlier, the Italian Bishops Conference (CEI) slammed the planned hiring of two gynecologists at the San Camillo Hospital on a contract that reportedly envisages their dismissal if they refuse to perform abortions because it is against their consciences.
The CEI said conscientious objection was "a right" that must be preserved.
Women regularly complain about the difficulty of obtaining an abortion in Italian hospitals, where conscientious-objector doctors are a majority.
According to the latest figures, seven out of 10 Italian doctors are conscientious objectors to abortion.
Lazio Governor Nicola Zingaretti said the proposed contracts were a way of making sure Italy's abortion law is upheld.
"We have to face up to the issue of the real implementation of Law 194, also by trying innovative forms of a law that would otherwise not be upheld," Mr Zingaretti said.
The governor added that the call for the two posts at San Camillo was a limited one, and the overall right to conscientious objection was "100 per cent guaranteed".
The head of the Italian Free Association of Gynecologists for the Application of Law 194 (LAIGA), Silvana Agatone, made a shocking revelation in light of the debate.
"Abortion must be present in all hospital bodies, according to article 9 of Law 194. But this is not so; more than 40 per cent of hospital bodies are illegal in Italy," Ms Agatone said.
The president emeritus of the Constitutional Court, Cesare Mirabelli, told Italian TV that "a competition that excludes those who are objectors is of dubious Constitutionality" and discriminatory.
