"All our savings go to IVF…Then you get that negative pregnancy result. There's another $6,000 gone" - Grace. Grace is one of the tens of thousands of Australian women who have put their faith in fertility treatments to help conceive a much longed for baby. At 42, she's been through six unsuccessful rounds of IVF. The physical, emotional and financial toll is huge. Julia too, had dreams of becoming a mother, undergoing 8 rounds of fertility treatment. And while she willingly put her body in the hands of fertility specialists, she struggled to get a clear answer on just what her chances of having a baby actually were. Four Corners looks at the booming business of fertility, where the industry pulls in more than half a billion dollars in revenue, and asks whether clinics are giving women clear, unambiguous advice about their chances of giving birth. Many fertility specialists say it's up to individual women to decide how much treatment they can take. But as this program shows, there are concerns, even from industry insiders, that some women undergoing IVF don't actually need it. Others warn against the practice of upselling - where women are sold expensive and unproven treatments that one doctor says is akin to snake oil. And disturbingly, they also have concerns about the potential harm fertility treatments could be causing for women - including potential links to cancer.

Four Corners is Australia's premier television current affairs program. It has been part of the Australian story since August 1961, exposing scandals, triggering inquiries, firing debate, confronting taboos and interpreting fads, trends and sub-cultures. Its consistently high standards of journalism and film-making have earned international recognition and an array of Walkleys, Logies and other national awards.
