Fwiw I know some straight couples who have had IVF and have sued the clinic when they ended up expecting a boy instead of a girl. I don’t think this in itself makes the couple awful or ‘not ready to be parents’.
The issue here is that the IVF clinics in the USA offer gender selection and they failed at doing that. That, in itself, has little to do with the fact we are talking about a gay couple.
I have issues with their reasons of wanting a boy rather than a girl, I have to say. And seeing that one of them is obviously the father, I’m also wondering what will happen to their involvement with the child….
In the case of a straight couple now expecting the child, they might be unhappy with the sex of the child but will raise the child. With surrogacy, the door is obvioulsy wide open for them to then just step out and refuse the child (how they can do that is another matter. And refusing to raise the child DOES make them unfit parents in my book)
