The genus Vertigo is summarized to be monoecious, meaning that the snail has both the male and a female reproductive organs. The Vertigo genus is known to have a well developed penis with a shortened prostate, a smooth uterus, and a free oviduct (Pilsbry, 1939-1948).

   There are a number of different sexual systems and reproductive strategies, behaviors and anatomy that land snails take part in (Sterki, 2007). Vertigo is hermaphroditic, meaning the organism has reproductive organs normally associated with both male and female sexes. Many of these land sails have the ability to self-fertilize but they can also take part in reciprocal mating, in which each hermaphroditic snail can act as both a female and a male and exchange sperm (Sterki, 2007). Vertigo paradoxa is oviparous, a reproductive method in which the organism lays eggs (Sterki, 2007).

   Different Vertigo species live in a variety of different habitats. These habitats range from dry grasslands to forests (Anderson, 2004). Because of this variety in habitats, this may influence the time where the conditions are right for the land snails to breed. This causes different species of land snails with different habitats to have different breeding habits and preferences (Anderson, 2004).
