Iui procedure

The IUI procedure can be an effective treatment for some causes of infertility in women under age 41. The washed specimen of highly motile sperm is placed either in the cervix (intracervical insemination, ICI) or higher in the uterine cavity (intrauterine insemination, IUI) using a sterile, flexible catheter.
The intrauterine insemination procedure, if done properly, should seem similar to a pap smear for the woman.
Most clinics offer for the woman to remain lying down for a few minutes after the procedure, although it has not been shown to improve success.
Many studies have shown that insemination with drugs to stimulate multiple eggs to ovulate gives a higher success rate than doing IUI without drugs, called natural cycle IUI.
In this procedure, a concentrated specimen of sperm processed in the lab is placed in the uterine cavity using a thin, plastic flexible catheter through the cervix. On the day of IUI, the husband collects the sperm in the laboratory and the sperm sample is specially prepared in the andrology laboratory by "sperm washing". Intrauterine insemination (IUI) is a procedure in which concentrated motile sperm are deposited into the uterus through the cervix by a soft insemination catheter. The cost of IUI is much less than that of an IVF cycle and can vary dependind on whether other treatments are also required. Most women that are having trouble producing a baby on their own will begin the fertility process with the IUI procedure, which is an outpatient fertility treatment procedure that is less invasive than other options, such as IVF. If you have tried at home to have a baby for several months with no success, many doctors will recommend that the woman undergo an IUI procedure. The reason behind the fertility problem is the primary factor in deciding whether a woman or a couple is indeed an IUI candidate. As a general rule, when the infertility cause is unknown, the IUI procedure may still be used at the beginning depending on other factors that the doctor may take into consideration. While the procedure itself is straightforward, the techniques used that lead up to the actual insemination vary between clinics and physicians.


Natural Cycle – The most basic of the procedures, the natural cycle allows for insemination to take place between the 12th and 15th day of the woman’s natural ovulation cycle. Monitored Cycle – Prior to the time that ovulation is expected, some doctors will use ultrasounds to time the IUI procedure by watching the ovaries. The success rates of the IUI fertility treatment vary with most studies showing the success rate between 10 and 20 percent. Just as with any procedure, there are pros and cons of the IUI procedure that a woman and couple should take into consideration. However, with IUI, the sperm is washed first, which increases the chances of pregnancy due to the fact that the sperm is ensured to be of the highest quality. While the IUI procedure does not necessarily increase a woman’s changes of conception by a significant mount, it is the first recommended step for fertility treatments.
It is reasonable to try IUI for longer in women with polycystic ovaries (PCOS) and lack of ovulation that have been given drugs to ovulate. Therefore, IUIs must be properly timed so that sperm show up for the date while the eggs are still viable. The woman could develop an infection in the uterus and tubes from bacterial contamination that originated either in the semen sample, or through a contamination of the sterile catheter in the vagina or cervical area during the procedure. Different techniques are used including a simple swim up procedure or the Density Gradient procedure according to the quality of the semen sample produced on that particular day. Lower sperm concentration or motility may not yield enough motile sperm to obtain a visible pellet for IUI to be practical. Women under 35 years of age may be encouraged try attempt to conceive at home for up to one year prior to trying fertility treatments; however, IUI is often recommended at six months for a woman over the age of 35. Women that can ovulate, either with medication or on their own, and have open fallopian tubes are most likely to achieve a successful pregnancy with IUI.
Once one mature follicle has developed, the IUI procedure is planned for the following day.


While these percentages aren’t much higher than what you could expect from natural conception, IUI is the first step in attempting to conceive a baby after at-home failed attempts. Should there be blockage in a woman’s fallopian tubes, the IUI procedure will not be successful. IUI has also been shown to have a reduced success rate in younger women with a significantly elevated day 3 FSH level, or other indications of significantly reduced ovarian reserve.
After the IUI, daily supplemental progesterone is given, usually in the form of a vaginal suppository, to support implantation and early embryo growth.
Usually, the woman will receive a HCG hormone injection before the procedure to help complete egg ovulation.
IUI can ensure smoother sperm traffic, bypass the cervical barrier, and shorten the distance to the distance ends of the tubes to improve the chance of fertilization.
The sperm preparation (IUI Prep) is subsequently stored in an incubator up to the time of the IUI procedure. Compared to regular intercourse, the IUI procedure inserts the sperm higher in uterus so that it can ultimately have a head start.
If a woman does not have a regular cycle each month, timing the IUI can be rather difficult resulting in the woman having to take medication or monitor her ovulation daily. IUI can help improving the odds by delivering millions of sperm into the more hospitable environment of the uterus while reducing the distance the sperm have to travel to reach the egg at the end of the tubes.
