Not really, no. An older male may have a lower sperm count and lower number of viable sperm, but if the male is still producing generally there is still more than enough to fertilize any eggs released by the dam. Biggest factors affecting litter size are how many eggs the female releases at ovulation and then how many of those successfully implant and grow.
