You can induce ovulation in a frog every four months.
The first few times will yield the highest quality eggs, but you will still get good eggs
from a frog that is several years old- provided that she is healthy. It is advised that you
wait 4 months between inducing the frogs. A rest period under 4 months does
not provide sufficient recovery time and the eggs will be unhealthy. It is ultimately in
your best interest to be patient.
