a male is stronger
The male rats (or mice) used in labs do not usually get neutered.
Female rats don't just turn into male rats. Sometimes a male rat's testes will be withheld in his body as a result of stress and he will appear to be female. Of course in such a situation, he is still male.
Males. Female rats tend to be more active. Male rats tend to get lazy as they mature.

Only male rats have testicles.
There are various different experiements performed on rats, & they quite often vary between male & female results. Male rats are not a high choice for experiments, but should a test to be used for men need to be created, then male rats would be the test subjects, & vice versa for females/
