Why must these women give in to a (purely psychological?) urge to become biological mothers? Maybe, with some of their free time--just a few hours a month--they could hang out at the local crisis pregnancy center, lend a hand. Encourage a scared young woman, facing an unplanned pregnancy, to see adoption as an alternative to abortion. Save a life already created instead of starting from scratch. These centers need all the help they can get.
Artificial insemination, IVF, etc...these procedures do nothing, absolutely nothing, to decrease the incidence of abortion.

I don't understand it myself. I've been married 20 years and never had the desire for children, so I never had any. You should see the flack I've gotten on FR for my "selfish" decision! What posters fail to express is why it's any of their business. I guess if you don't do what the posters generally think is right in your own life, they'll let you have it, whether you have kids or not.
