Intrauterine Insemination (IUI)
Intrauterine Insemination is a technique that can help treat certain kinds of infertility in both men and women.
Intrauterine Insemination (IUI), also known as artificial insemination is usually recommended to accompany ovulation induction cycles to increase pregnancy chances. When an IUI is performed, the partner's semen, after its seminal plasma has been washed off, is directly injected into the uterus.
IHR's expertise in Intrauterine Insemination lies in our willingness and ability to individualize our approach to best suit each and every one of our patients. If you have any questions as you review the material on Blastocyst, please contact us for a FREE IUI E-Mail Consultation..
When male infertility is a factor, IUIs empirically improve pregnancy rates over regular intercourse. It also improves pregnancy rates if cervical factor infertility is present (i.e. the cervical mucus inactivates semen motility) and in the presence of mildly abnormal semen, which can constitute a case of general male infertility.
Intrauterine Insemination process includes preparing and delivering sperm so that a highly concentrated amount of active motile sperm is placed directly through the cervix into the uterus. IUI is typically performed with fertility drugs for the female patient. Thus, for infertility patients, IUI is commonly performed as a low-tech, cost-effective approach to enhancing fertility in patients.
There are several techniques available for preparing the sperm for IUI. All of the techniques involve separating sperm from seminal fluid. It is not possible to inject semen that has not been separated directly into the uterus because of chemicals in the fluid that can cause extremely painful uterine contractions. We primarily use a method of sperm separation called "Density Gradient Separation". In this technique, motile sperm are separated from dead sperm and other cells through the use of viscous solution. Approximately 2 hours are required to process the sperm. After preparation, the sperm concentrate is placed through the cervix into the uterus by using a thin, flexible catheter. The time required for insemination is ~5-10 minutes. The patient may experience mild cramping during the procedure but this symptom should resolve shortly after the procedure is completed. There is a small risk of infection following this procedure (less than 1%). A hysterosalpingogram should be performed prior to IUI to document at least one open fallopian tube.
Every male partner providing a semen specimen for IUI preparation must be tested for infectious diseases. If a woman is using donor sperm from a sperm bank, we require that she have infectious testing performed prior to initiating donor sperm inseminations. The specific tests required are HIV, HTLV I, RPR (a test for syphilis), Hepatitis B Surface Antigen, and Hepatitis C antibody.
Studies suggest success rates with IUI are enhanced with the addition of moderate treatment of the female partner with medications. A decision regarding medication to stimulate the ovaries is made in consultation with the physician. Alternatively, patients may be advised to take injectable fertility drugs which are more aggressive in stimulating multiple egg release from women (the more eggs that a woman produces during a treatment, the higher the chance for success but also, the higher the chance of a multiple pregnancy).
Though the pregnancy rates for women undergoing artificial insemination may not be as high as they are for some more advanced techniques, this technique has a key advantage: it's a simple procedure with few side effects.
Perhaps less known is our work with individuals and couples who are considering assisted reproduction, but who are uncertain of their next step. We encourage anyone, before they make a decision, to consult with us. Currently, we are offering a FREE IUI E-Mail Consultation.
