I can relate. I have an ultrasound tomorrow on my reproductive parts. The doctor suspects endometriosis (causes scar tissue on uterus and other internal organs and just generally wreaks havoc), and I hope it's serious enough to require a hysterectomy. It's unlikely, of course, that it's *that* bad; doctors tend to assume that their patients don't want their reproductive organs removed and will therefore try other less invasive treatments first.
A hysterectomy is usually the 'worst case scenario' for many women. Sometimes I think I should feel terrible for wanting the 'worst case' to happen to me, because I know of a few young women who needed a hysterectomy and took the news rather hard. But me? Hell, I'd celebrate.
Forgive me if I'm not 100% educated on MtF bottom surgery, but it seems to me that the only thing that would be required for SRS is the tissue of the scrotum (to form the labia), not the actual testes. The testosterone factories could probably be removed, but the skin encasing them should remain in place... I do know that if an orchi is performed in the event of testicular cancer, the patient can elect to have prosthetic testes placed in their scrotum for a more normal appearance post-op.
