However, longterm mixing of acetaminophen (the ingredient in Tylenol) and aspirin can result in renal (kidney) damage. It will not happen if you mix them once or twice, but mixing repeatedly over a long period of time is dangerous.
IUI stands for intrauterine insemination. It is sometimes called artificial insemination as well. Essentially, IUI is a technique to directly place sperm into the uterus. IUI is a technique to overcome a variety of mild fertility problems, many of them on the male side.
What is an IUI and how is it done? An IUI -- intrauterine insemination -- is performed by placing a very thin flexible cannula (tubing) through the cervix (neck of the womb) and injecting washed sperm directly into the uterus (womb). The whole process takes about 5 minutes - it usually only requires the insertion of a speculum and then the cannula.
