Intrauterine Insemination (IUI) is a fertility treatment that involves placing sperm inside a woman’s uterus to facilitate fertilization. The goal of IUI is to increase the number of sperm that reach the fallopian tubes and subsequently increase the chance of fertilization.
IUI provides the sperm an advantage by giving it a head start but still requires a sperm to reach and fertilize the egg on its own. It is a less invasive and less expensive option compared to In Vitro Fertilization. The most common reasons for IUI are low sperm count or decreased sperm mobility.
Before IUI is carried out, you and your partner's fertility will need to be assessed to find out why you are having difficulty conceiving and to see whether IUI is suitable for you.
Your chances of success with IUI depends on:

Pre-ejaculate fluid (precum) is a normal part of physiology for lubrication produced by glands of the penis to facilitate sexual intercourse. The odds of getting pregnant from precum are very small. It’s estimated that 4 in 100 women will get pregnant using the withdrawal method correctly. Even if the man pulls out and ejaculates away from the vagina or vulva area, there is a 4% chance that pregnancy may result. These pregnancies are due to those few sperm cells in precum. If a man never inserts his penis into your vagina, and only the tip of his penis (with precum) comes into contact with the outside of your vulva, it's extremely unlikely that precum on the outside of the vagina will lead to pregnancy. However, the odds are not guaranteed. It is still theoretically possible for pregnancy to occur.

Urine is naturally acidic, and some of that acidity lingers in the urethra even after you've passed urine. The problem is that sperm cells are sensitive to pH levels, and the acidity of urine can kill sperm cells. Once the sperm come into contact with urine, they don't survive very long. Since sperm can only live for a maximum of 5 days in the female reproductive tract, only a small number of sperm will even survive the long journey through the female reproductive tract.

Even if a man pulls out in time, pregnancy can still happen. Some experts believe that pre-ejaculate, or pre-cum, can pick up enough sperm left in the urethra from a previous ejaculation to cause pregnancy. For every 100 people who use the pull out method perfectly, 4 will get pregnant. But pulling out can be difficult to do perfectly. So in real life, about 22 out of 100 people who use withdrawal get pregnant every year that's about 1 in 5.
