Intrauterine insemination (IUI)

Intrauterine insemination (IUI) is a form of assisted insemination (AI). The technique is used in only a few circumstances, for example when:

  • There is a physical problem with sexual intercourse
  • Scarring of the cervix prevents sperm penetration
  • Donor sperm is required.

When there is low sperm count, or if there is endometriosis, assisted insemination techniques such as IUI are not as effective as in vitro fertilisation (IVF). In addition, the fallopian tubes must not be blocked. The technique is not recommended when the cause of infertility is unknown.

 

Sperm Injection Into Uterus

 

IUI

IUI is a technique in which sperm are placed into a woman’s uterus using a soft, thin plastic tube around the time of ovulation.

An insemination cycle might or might not include ovarian stimulation.

The cycle is monitored with blood tests and ultrasounds so that insemination can be timed precisely to coordinate with ovulation.
