Unless this person was significantly older, I am guessing it was a line, like "my Dr said I can't have kids", or similar, to get out of wearing a condom. I am 31 now, but I heard that more than once when I was in college.
Regardless, now that she has made that claim, I am sure they are looking into it. It would be very negligent if things ever got to a trial phase and they hadn't looked into it.
ETA/ I say the bit about significantly older because I have two male friends who have been quite adamant that they didn't want kids and had trouble finding a doctor who would perform the surgery at their age.
One has since changed his mind and is a very happy dad. The other is counting down until he is 38, which is the youngest he could find a doctor willing to do it.
The others in our area seemed pretty set on 40 as the limit unless there was a medical necessity or a high risk of genetic disease to the man's potential offspring, or if he were married and his wife would sign off on it.
