Female fertility is affected by age. After puberty, female fertility increases and then decreases, with advanced maternal age causing an increased risk of female infertility. In humans, a woman's fertility peaks in the early and mid-20s, after which it starts to decline slowly, with a more dramatic drop at around 35.

There is still some debate about how to classify this animal (as a unique species, as a subspecies of gray wolf, or as a close relative of the red wolf), but USFWS is currently managing it as a subspecies of the gray wolf.
