Is it ever explicitly stated in the Anime or Manga that Rei is sterile?
If so when?  (I just need to know what ep it's in)

Thanx in advance

I don't think they ever say that she's sterile...

There is a linein episode 14 'weaving a story 1'. 
It's during Rei's monologue about herself 
"Who am i? A woman who does not bleed."
