Imperforate vagina in mice: per cent incidence and surgical repair

An inbred strain maintained at Nagoya University, Laboratory of Animal Genetics, produced high incidence of imperforate vagina as 12.21% of occurrence in females, herein designated as Imv strain. Selected females with imperforate vagina in this strain were surgically repaired and subsequently mated with their littermates. These matings produced a 12.76% incidence of imperforate vagina.
