I wonder if there are some concerned IVF doctors or nurses who, like with other oversights or scandals in health, would raise their head above the parapet and whistle blow if they had protection of anonymity.
If you have ex midwives in private clinics seeing the same faces appear regularly for implantation or if there was a national register with red flags for or on serial 'repeat customers' who had multiple surrogate pregnancies maybe stronger advice could be presented and doctors could refuse more easily, for fear of being sued.
I'm not a conspiracy theorist but I don't trust the clinics to put the best interest of the patient at the heart of what they do as that place is occupied by cold hard cash under the pretence of 'helping' the infertile couple who also don't have the best interested of the surrogate mother at their heart. They just want the baby.
This woman says she does it willingly but she sounds like she needs some therapy to me, someone should be exploring with her, her need (obsession?) to be pregnant/give birth. The way she talks about pain has an element of self harm to it somehow.
