More than 7 million Americans want to have a baby but can't without the help of pricey infertility treatments.

Earlier this month, Connecticut joined 14 other states in mandating that insurers cover in-vitro fertilization (search). And like some of those states, the Constitution State imposed a 39-year-old age limit for women seeking the procedure, causing some women to be up in arms.

Treatments can be as high as $12,000 to try to get pregnant (search). Some moms, like Teresa Le Ruo, 42, of Connecticut, can't afford treatment and don't meet the age requirements for infertility treatments.

"We feel insurance should cover it," Le Ruo said. "They cover elective terminations of pregnancies. I don't see why they can't cover my in-vitro fertilization."

Le Ruo and her husband adopted a baby last year but the birth mother later took the child back. As an alternative to adoption (search), Le Ruo wants to try the in-vitro fertilization treatment.

"What are they going to tell a woman with breast cancer? 'Oh, I'm sorry, your stats for your age aren't very good, so we're not going to treat you?'" Le Ruo asked.

Age limits also raise questions with recent statistics showing that the number of women older than 40 having babies has risen by 58 percent over the past decade. Some insurers say despite the statistics, they don't change their position that it costs too much to insure all ages of women.

"For every 1 percent that health care benefits rise, several hundred thousand people across the nation lose their coverage, become uninsured," said Susan Pisano, spokeswoman for America's Health Insurance Plans.

But states including Pennsylvania, California, Florida and New Hampshire are still looking into offering some type of insurance coverage to residents who want to try in-vitro fertilization.
