> What are the breeding age time periods of male and female gerbils?
With the experience I had, it's seems typical that the beeding age period is
from about 3 months of age till up to 24 months of age.
> At what age does a male reach puberty?
Not sure, maybe as young as 7 weeks?
> Can a male gerbil impregnate a female up until he dies?
As far as I know, yes he can.
> Is he intersested up until he dies?
He probably is as long as he is with a young enough female.
>Does his age affect the quality of his sperm and his offspring?
I'm sure it affects the quality of his sperm, but not sure about the
offspring.
> At what age does a female reach puberty?
I've heard some females getting pregnant as young as 7 weeks, this usually
happens if she is housed with an older male.
> At what age does she have menopause?
I think as early as 18 months.
>What is the average number of litters a female will have in her lifetime?
With my breeding pairs, it was anywhere from 10 to 18 litters.
