Her partner is infertile.

That my um... My partner is... Um infertile." She had started out so strongly but quickly begins to fumble her words and get increasingly embarrassed as her head drops once more to staring into her lap.
"Well I'm sorry to hear that..." somehow you're not sure this is enough comfort as the woman seems clearly sad, "at least now you know and can solve it. And now you know you're fine." this seems to give her a little confidence as her head comes up again.
"I know but that's the worst part. I'm so fertile!" Annoyance and frustration creeping into her voice now, almost with dashes of despair thrown in. "I was one of the most fertile people they've ever tested. They even asked if they could have some of my eggs for further testing and research! It's all my partners fault he's probably been shooting blanks forever!" she seems on the cusp of crying. You decide you must choose your next words carefully as you have to approach the topic of further loans for the treatment.
