Essentially for my story my Evil Empire needs a constant and huge amount of new population to conscript for their armies. The way they accomplish this is by forcing every female member of society (aside from those in the Upper Courts that is) to continuously produce children.
With access to near-future technology, what is the largest amount of healthy children a mother could give birth to in her lifetime?
This can include using any manner of IVF or other technologies, the only requirement is that the offspring survives the birth in a healthy enough state to be able to grow to adulthood and hold a gun.
Also, considering the fact this is an evil empire, Ethics and Morals need not apply.
