The availability of medical infrastructure and potential surrogates, combined with international demand, has fueled the growth of the industry.

A person agreed to by other potential surrogates would rank first, followed in order by a spouse, an adult child, a parent, an adult sibling, and a close friend.

They had been at this for a while and already had screened many potential surrogates.

"Her capacity for denial should have been a central thing that was looked at in evaluating her as a potential surrogate," Dr. Nickman said.

"If this convinces potential surrogates not to enter an agreement unless they're absolutely sure, then that's what we want," he said.

"We will be developing a centralized database of all potential surrogates (elected officials, Democratic activists, celebrities, other supporters)," the memo said.

She guided them through complicated medical procedures, helped them vet and select potential surrogates, and lifted their spirits with they felt hopeless about having a child.

So they tried two other potential surrogates.
