KEY POINTS:
More than 100 gay Australian couples have paid A$80,000 ($101,664.76) to create a baby using rent-a-womb women in the United States.
The controversial scheme, branded as "one-stop baby shopping", is becoming increasingly popular among professional gay men in Sydney and Melbourne, according to the Fertility Institutes based in Los Angeles.
"We've seen more than 125 gay couples from Australia who have gone home with a baby," said the clinic's medical director, Dr Jeffrey Steinberg.
"We're up to six to eight a month now, which is a four-fold increase over two years ago."
The first programme dedicated to two-father families allows gay men to pay for surrogate children, a practice which is illegal in Australia.
