A DNA bank is a repository of DNA, usually used for research. The Royan DNA Bank, for example, collects the DNA of male and female infertile patients and couples with repeated miscarriages, for scientific research. Most DNA provided by DNA banks is used for studies that attempt to determine the reason behind idiopathic infertility and abortion, as well as to investigate genetic diseases related to infertility and abortion.
