It is a fertility treatment where fertilization is facilitated by placing sperm inside the uterus of the woman. With the help of IUI the number of sperms reaching the fallopian tube increases and thereby the chances of fertilization rise. It is one of the best methods to use when the sperm count is low, and their mobility is less than required. However, it can also be used if the conditions like unexplained fertility, cervical mucus, cervical scar tissue or ejaculation dysfunction are present.
Intrauterine insemination is less invasive fertility treatment as compared to others. It is also less expensive and therefore can be easily affordable. The entire process endows a head start to the sperm to enter inside the fallopian tube; however, fertilizing the egg will be its own process. The success rate of IUI with just one cycle is relatively less but a continuous 3 to 6 cycles of IUI the rate of pregnancy goes as high as 80%.
Intrauterine insemination (IUI) is a simple Procedure .That Sperm directly inside your uterus, Sperm get closer to your egg. If the sperms are present in the tubes when the egg is released from the ovary, sperm and egg can meet and fertilise in the fall opian tube.
IUI stands for intrauterine insemination. It’s also called donor insemination, alternative insemination or artificial insemination.IUI works by putting sperm cells directly into your uterus sperm helping and get closer to your egg.
Then doctor puts the sperm right into your uterus. Pregnancy happens if sperm fertilizes your, egg the fertilized egg implants in the lining of your uterus.
If the man has poor sperms quality, the couple may benefit from IUI.
Unexplained causes: The most common use for IUI is when no specific cause for the infertility found. Sub-fertile women are given medications (by mouth or as an injection) to make their ovaries produce more eggs and timed IUI is done around the time of their egg release. The goal is to increase the chance pregnancy by putting more sperms in contact with more eggs.
Cervical stenos is or abnormalities: IUI is helpful when a woman's cervix has scarring that prevents the sperm from entering the uterus from the vagina or there are problems with the quality of the mucous.
Problems with sperm delivery: IUI can also be used couples which the male parent t erectile dysfunction or is not able to ejaculate effectively, or at all. For example, retrograde ejaculation is when the sperms are released backward into the bladder, instead of through the penis, at the time of male orgasm. Prior surgeries or medicals conditions, such as diabetes, can cause retrograde ejaculation. Also, IUI may help if the man has an abnormals urethral opening (opening of the penis).
Lack of an ovulation (an ovulation): Most of the time women who do not release an egg regularly (ovulate) can become pregnant through intercourse. Sometimes, IUI may be helpful.
Fertility preservation: The Men may collect freeze (cry preserve) their sperm for futures use before having a vasectomy, testicular the surgery, was or radiation/chemotherapy treatment for cancer. The sperms may be used later and used for IUI.
Third-party reproduction: IUI is used when couples use sperms from a man who is not the woman’s partner to have a baby. This is called donor insemination (DI). DI is done when the male partner has no sperms or when the sperm quality is so low that his sperm cannot be used for conception, and in vitro fertilization is not an option. DI can also be used if the man has certain genetic diseases that he does not wants to pass on to his children. Single women or lesbian couples who wants to have a baby may also consider DI.
How are sperm collected? Semen needed for IUI can be collected in severals ways. Most commonly, the man masturbates into a sterile glass or plastic cup that is provided by the doctor's office or an anthology laboratory, which specializes in dealing with male health issues. Sperms can also be collected during sex in a special condom that the doctor provides. If a man has retrograde ejaculation, the sperms can be retrieved in the laboratory from urine he has collected.
Men who have a difficult time erection despite using medications, as well as men with a spinal cord injury, may be able to produce a sperm sample with the help of vibratory stimulation or electro ejaculation. Vibratory stimulation commonly takes place in an offices and uses a handheld vibratory device. Electro ejaculation uses electrical stimulation in order to produce a sperm specimen. For men with a complete spinal cord injury, electro ejaculation is commonly performed in the office, while patients with an incomplete spinal cord injury may have an electro ejaculation procedure performed under anesthesia in the operating room. For more information on these procedures, see the ASRM fact sheet titled Sperms retrieval in men with spinal cord injury.
Once collected, semen then washed the laboratory concentrate the sperm and removes the seminal fluid (seminal fluid can cause severe cramping in the woman). This process can take up to 2 hours to completed.
IUI is performed around the time that the woman is ovulatings. The IUI procedure is relatively simple and only takes few minutes once the semen sample is ready. The woman lies on an examining tables and the clinician inserts a speculum into her vagina to see her cervix. A catheter (narrow tube) is inserted through the cervix uterus and the washed semen sample is slowly injected. Usually this procedures is painless, but some women have mild cramps. Some women may experiences spotting for a day or two after the IUI.
The success will vary dependings on the underlying cause of the infertility. IUI works best in patients with unexplained infertility, women with a cervix that limits the passage of sperms, and men who are unable to ejaculate effectively. For example, for unexplained infertility, the pregnancy rate with IUI is double that over no treatments.
IUI does not work as well for men who produce few sperms or have slight abnormalities with their sperm and does not help women who have severe fallopian tube disease, moderate to severe endometriosis, or a history of pelvic infections.
Overall, if inseminations are performed every month with fresh or frozen sperms, success rates can be better. The success rates depend on whether fertility medications are used, age of the woman, and infertility diagnosis, as well as others factors.
If a woman is taking fertility medications to increases the number of eggs when she has an IUI, her chance of getting pregnant with twins, triplets, or more is greater than if she were not taking fertility medications. Having an IUI does not increases the risk of birth defects. The chance of birth defects in all children is 2% to 4% whether conceived naturally or from IUIs. The risk of developings an infection after an IUI is small.
