Having read a summary of the available research into outcomes of genital surgery in these males, what she is proposing is even worse than it appears.
The average complication rate in adults is one in three, ranging from light infections, urinary issues, bowel perforations to death. 30% are not able to reach orgasm post-surgery.
But that is only in penile inversion surgeries. All other methods have a higher risk of complications and worse outcomes in terms of function and satisfaction.
It's important to note that she is not advocating for performing the best surgery available right now, the one that has the best outcomes in terms of risk and function, but for deliberately choosing a path for these boys that leaves them only the lesser surgery with higher risk and worse outcomes.
What she is proposing is already unethical, irresponsible, cruel and inhumane, but she does so knowing she is closing off the path to the least risky medical treatment as well. For children.
Addendum: please note that the quality of evidence as to outcomes of genital surgery in adult males is judged to be low. There is a lack of research in the first place and a lack of long-term follow-up. Where the latter does happen, patient surveys use inconsistent rating systems and don't measure the same data across studies.
In other words, they don't collect enough data and the data they do have cannot be compared. In adults. IIRC there is no data about outcomes in children.
