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.
