Intrauterine insemination (IUI), also known as ‘artificial insemination’, is often used in the treatment of unexplained infertility or mild male infertility. When a woman is ovulating, the male partner’s or the donor’s sperm is collected. After the semen sample is ‘cleaned’ in a cell culture media and concentrated through centrifugation, it is inserted into the woman's uterus through a tiny straw or catheter. The concentrated sperm is released and swims to the fallopian tubes where one will hopefully meet with the egg and fertilization will occur.
The chance of pregnancy for patients with unexplained fertility that are treated with IUI ranges from 8-10% per month. SOURCE
Depending on the severity of the male patient’s semen problem, the success rate of IUI varies. According to recent studies, when the male has mild to moderate infertility, couples might have an 8-12% chance of beginning pregnancy each month while undergoing IUI treatment. More than 90% of pregnancies occur during the first 4 months of treatment and unfortunately, the success rate of IUI decreases to well under 5% per month when treatment has gone longer than that. This low success rate is also true when IUI is used for couples where the male has severe infertility. Severe infertility is characterized by having less than 5 million moving sperm cells per sample.

When a single woman or family is in need of donor semen, intrauterine insemination is a safe treatment option. Sperm banks hold cryopreserved sperm for purchase. The origin of the sperm is the only differing process between donor IUI and the IUI previously described.
Patients may expect a 10-12% chance of pregnancy with each month of donor sperm IUI based on research studies. SOURCE
