"Some of that has always been that way — if you have a disability or heart disease or cancer," he said. "If you have money and power you get better care than others."
But Florida psychologist Judith Horowitz, who counsels couples who undergo fertility treatments, challenges the idea that insurance companies should have to pay for expensive treatments for older mothers.
She supports a public information campaign to educate women before they make the tough choice to delay childbirth for a career. Many of her own patients are shocked when a doctor brings up the topic of "waning fertility."
"It heightens one's awareness and one's fear," she said. "It seems as if physicians are pushing children to become mothers and reversing the trend — that education and career are less important."
She added women need to be "armed with the facts" to make intelligent choices about when to have children.
Meanwhile, Katz told the New York Post, that her decision to be a single — and older — mother was one "that I felt if I didn't do, I would regret for the rest of my life."
The city councilwoman said she hoped her experience would be a help to others with fertility struggles. As for inequities in insurance coverage, she said she hopes to take the issue with her on the campaign trail.
"The comptroller is a good bully pulpit," she said. "It's good to set an example for other folks."
Still, even after the painful and grueling IVF treatment, being a single mother seems simple, according to Katz.
"I am simply having a baby," she said. "People have been doing it for generations."
