When is IUI used?

IUI is a fertility treatment often selected by couples who have been trying to conceive for at least one year with no success. IUI may be selected as a fertility treatment with any of the following conditions:

Unexplained infertility
Low sperm count
Decreased sperm mobility
Requirement of donor sperm
A hostile cervical condition, such as cervical mucus that is too thick
Cervical scar tissue from past procedures or endometriosis
Ejaculation dysfunction

IUI provides the sperm an advantage being kept nearer to the place of fertilization, but still requires a sperm to reach and fertilize the egg on its own.
