Intra Uterine Insemination (IUI)

Artificial insemination (AI) is a method by which the sperm is placed into the female reproductive system. Intrauterine insemination (IUI) is a laboratory procedure to separate fast moving sperm from the more sluggish or non-moving sperm. These fast moving sperm are placed into the woman’s womb at the time of ovulation when the egg is released from the ovary, in the middle of the monthly cycle.

 

In that, IUI is the one most commonly performed and it involves placing sperms into female uterus.

The IUI is a low-tech solution to infertility issues and it was the first technique used to assist the couples who have difficulty in conception.

Done by using sperm from women's husband or partner [artificial insemination by husband (AIH)] or from anonymous or known sperm donor [artificial insemination by donor (AID/DI)].

The rationale is to increase the conception rate in the couples, by increasing the density of gametes at the time and site of fertilization.

IUI can be done around the ovulation time.

To get good success rate, the insemination timing relative to ovulation is important.

A wider time frame can be used. Usually 12-36 hours after hCG injection, IUI is planned.

US guidance in IUI improves the PRs. It also reduces the chance of difficult IUI.
