I hesitate even to bring this up, in that it is something that has no moral coloration whatsoever, is not her fault, and is really none of anyone's business, but Ann Coulter may
not have been able to have children. There are women who have AIS (androgen insensitivity syndrome), and she has some of the hallmarks --- tall, thin, quite attractive (if you ask me), nice complexion, lustrous hair. In essence, they are biologically male, but develop in every way as females, aside from not having a female reproductive system. It is kind of "intersex-but-not-intersex", in that in many cases, there is no indication there is anything "wrong" until they eventually end up never having periods and being infertile. Without getting too graphic, some AIS women would never be able to consummate a marriage --- they usually can, but there are degrees of AIS, and some are affected more profoundly in this way than others.
They really make quite striking-looking women --- jazz singer Eden Atwood, who has AIS, is positively gorgeous. The human embryo's "default setting" is to develop into a female, and it is only the presence of male hormones that nudge the developing embryo to become male. Men, when you are looking for something to be thankful for (and I'm assuming all of us men here are thankful to be men!
), reflect that but for the grace of God, you did not have AIS.
