The more fertile a swampert is depends on how large its gotten and its climate. Female swamperts grow much slower. Often the results in much younger males breeding with older females. Breeding causes much more strain on the females than males, and its likelier to fail the skinnier the females are. Females can produce nearing a thousand eggs, and if the female isn't fed well enough, they can die while producing so much. Unlike many other pokemon, swamperts will breed even if they are in ill health. Because of such an excess in failed children, runts and failed births are often ate.
Swampert 'heat' is most common in the earlier parts of the year. When courtship begins, males will show their interest in a female by raising their tail fins high in the air, and often thrusting a bit. Once they have successfully attracted a female, they will walk them around their territory as a sort of mating dance. During this mating dance, the two will rub the undersides of their hindlegs together, where their is a chunky, sensitive area. If done right, this mating dance can last longer.
Male swamperts will release their sperm in a jelly, leaving it in a safe warm part of the marsh water. During their trot, the male will lead the female to this 'jelly'. If she is truly interested, she will take the jelly into her, and begin fertilizing her eggs.
