Regarding a comment the author made in passing:
For the increasing number of people who have cataract surgery, the eye’s lenses have ben replaced with plastic, which usually have a fixed focus. (Artificial lenses that can be focused are under development.)
My dad recently had cataract surgery and I just assumed he was getting would be a deformable lens that would give him the ability to focus again. Does anyone know why it is so hard to develop such a lens ? As far as medical breakthroughs it seems like low hanging fruit and most people over the age of 45 could benefit from such a surgery since that is the age at which our lenses begin to harden and can no longer be shaped by our ciliary muscles.
It should be pointed out that the pituitary gland sits at the base of the brain and prolactinomas are not technically considered "brain tumors" because they're not in the tissue of the brain. So it's a mischaracterization to keep referring to this as a "brain tumor" and a bit of an odd one for someone trying to start a medical research effort.
Unfortunately, the reality is that sometimes life just doesn't deal you a good hand. I think it's sad this man is talking about children when prolactinomas are a leading cause of infertility and it sounds like, for a variety of reasons, this man's girlfriend has one that is very difficult to treat. While it's OK to always hope, it's also possible to cling to false hope so strongly that it prevents you from accepting and moving forward with the life you have instead of the life you envisioned.
Thanks for sharing your story too, perhaps this condition isn't rare. Coincidentally I once went into bar and vaguely recognized a roommate I hadn't seen in years. His appearance had changed and he now had remarkable Hulk like features. I restrained myself from asking but I honestly thought he looked great.
We chatted and he shared that he had "brain surgery" 2 weeks(?) prior to remove a tumor on his pituitary gland. He just woke up one day and his vision was distorted. The next day he woke up blind which lead to him getting a diagnosis and surgery. The tumor had also caused pituitary disfunction which induced giantism.
If I recall, the surgery was performed going behind his nose through an incision in his mouth above the posterior of his upper lip which differs slightly from the approach in the OP. It's amazingly fortunate that this is an option given it looks inoperable from the MRI.
I'll also share that towards the end of our conversation he thanked me for not commenting on his appearance and that he was self-conscious. It's compelling, especially when someone looks good, to mention it, but there's no need to lead with it.
