Do CR test animals have sex?

[Guest guest]

I just had this thought recently,

As far as I know the evidence for CR is based on mice/rats and

monkeys. The one time I saw these lab animals I realised that they

were in individual cages.

I maybe assuming too much here but isnt the fact that they dont get

to have sex affect their lifespan? Considering that sexual maturity

coincides with aging for most animals, isn't there a case for sex as

a factor for life span?

Does anyone know have any knowledge on this subject?

Thanks in advance
