How can you tell if a woman is sterile?

There are certain unexplained conditions such as : Congenital ( in-born) absence of a Vagina ( wow), Congenital absence of normal breast nipples, a flat-chested condition reminiscent of the Carrier Lexington ( which was on the hunt for somebody who well, was flat on top. ) Sorry, Miss Powers. Sterililty could also be caused by exposure to radiation or some other types of accidents.
