Women who've had a hysterectomy?
Women who've had a hysterectomy still have ovaries. You need to suggest a ovectomy (??? is that the right word??), but even then you can still harvest eggs.
The potential is there.
But, as we rack our brains for some kind of exception, we are simply emphasizing the rule: in the vast majority of cases, a male and female are potentially reproductive.
Jack and Jake are never potentially reproductive.
I certainly hope the state isn't going to snoop into my medical records to find out if I've had a hysterectomy.
