And also unnecessary. As Tax-chick notes ... "there is so much money and emotional force driving the industry that few want to learn the truth."
In the case of Dr. Arnold, she and her husband are catholic. Had she read up on church teachings and explored the basis for them, they might have consigned their desire for a family to adoption. Perhaps, being a physician, she leaned towards science rather than faith. However, her body is quite small and very compact (she is barely 3' tall). High doses of hormones were bound to have an effect ... it was emotionally painful to watch them go through the process of hope for a birth child, followed by the despair following the surrogate's miscarriage. Dr. Arnold's body was too small to carry the fertilized egg, hence the surrogate. Now this. She tweeted her fans the other day: “Exhausted after escaping my hospital bed for Zoey's doctor appt-Glad I could be there- now need rest during rest of my chemo.” Cancer is a big challenge as it is, of course, but battling the disease while getting a newly adopted child settled into the family adds a very difficult component to the mix."
Here they are, in happier days, with their son, Will.
