Le Fondre is the leading scorer for the Royals this season with seven goals, but has started just nine league games and is now mulling over his options.
He concedes that it has been a difficult time and says he could leave the Championship club before the January transfer window closes.
Questioned on whether he would consider an offer from another club, Le Fondre told BBC Radio Berkshire: "Of course I would."
Le Fondre came off the bench in a 1-1 draw against Nottingham Forest on New Year's Day, and has made seven further appearances as a substitute.
He added: "It is frustrating for me as a footballer and I want to play games. That is what I am paid to do. I am not paid to sit and watch games.
"I want to play games and that is something I have not been doing.
"I haven't played for two months now and for someone who is leading the goalscoring charts, to not have sufficient playing time is something for me to look at."
Manager Nigel Adkins has made it clear that he still regards Le Fondre as a key part of his plans and does not want him to leave.
He responded: "It is not on our agenda to be moving Adam on. We really want him to be at Reading Football Club."
