For more on marking an answer as the "Best Answer", please visit our FAQ.Depends on what breed of Hamster they are, if they are Syrian then chances are they were fighting as they generally don't like each other's company, also if your female is more than 12-14 months of age she will be sterile anyway, if she is younger then I would pop to the vets and get her checked.
As for other breeds, look here and there is information about it.
Good luck.
