TORONTO - Ontario's governing Liberals are promising to provide limited coverage of infertility services to more women who are struggling to get pregnant.

They say they plan to help would-be parents pay for one cycle of in vitro fertilization for all forms of infertility starting early next year.

But the province won't cover the costs of drugs and other services associated with IVF which can cost thousands of dollars.

Health Minister Deb Matthews wouldn't say exactly how much of the IVF costs will be covered, but estimates Ontario will pay out $50 million annually once the program is fully implemented.

She says the government hasn't decided yet whether it will offset the costs through a tax credit or through the Ontario Health Insurance Plan.

The Liberals made an election promise in 2007 to make fertility monitoring available earlier in life and make treatment "more accessible and affordable."
