[Physicist]

In the interest of flogging an Eohippus fossil, what I originally meant to say was not that it is logically impossible to inherit infertility, but that it is logically impossible for an infertile individual to pass along his traits.

[Bonaparte]

"...what I originally meant to say was... that it is logically impossible for an infertile individual to pass along his traits."

If that's the case, then I'm afraid you're wrong again. If the infertility is due to anything but lack of viable eggs or lack of viable sperm, an infertile individual can pass along his traits by artificial insemination (in vivo implantation) or by in vitro fertilization. Depending on the cause of the infertility, that infertile individual can also pass along his traits by other means, such as drugs or surgery. This would apply to both infertile males and infertile females.

With enough re-writes, I'm sure you'll eventually get this right.
