By that definition, I was certainly in error. However, by that definition, most "sterilizations" are not, since tubal ligation, among other procedures, does not stop egg production.
On a related point, it's interesting that proposals to "sterilize" the poor are rarely directed at men, only at women. Fiscally impractical, one would think, since one man can father many more offspring than one woman can deliver. The procedure is also much cheaper.
As for other factors such as blocked tubes, etc., that's referred to as 'unexplained infertility with underlying condition'. Trust me on this. I have endometriosis and am all to familiar with this term. I am still fertile, but another condition is making the likelihood of a natural pregnancy very difficult, if not impossible. Men can also be classified as 'sterile' and yet become fathers through IVF.
I don't think IVF is an evil thing. It helps so many couples become parents. Its the whack jobs like this doctor and Octopussy mom that ruin it those who are sincere and want to have a family.
I have a friend who had to use IVF due to male factor infertility (basically no sperm). She had two girls via IVF and had a very unexpected natural pregnancy. They were so thrilled, especially when doctors told them it would never happen.
