IUI – Intrauterine Insemination

IUI Program at GENESIS Fertility New York

Intrauterine Insemination

Intrauterine insemination (IUI), also known as artificial insemination, is a process by which sperm are placed directly inside the uterus. With natural intercourse, sperm are most concentrated in the cervix and only the most motile ones make their way through the uterus to the fallopian tubes. With IUI, a concentrated suspension of sperm is introduced through the cervix directly into the uterine cavity. This allows large numbers of sperm to reach the fallopian tubes, where fertilization would naturally occur. The procedure requires that the sperm be “washed” first. That is, the sperm must be separated from the semen (seminal fluid can irritate the uterus, causing severe cramping and pain). Sperm washing is performed under strictly sterile conditions and a variety of safeguards are maintained to ensure that semen samples cannot be switched.

The Insemination Procedure

The male partner is asked to produce a semen sample in a sterile container, this can be done onsite or at home. If the specimen needs to be obtained through intercourse with a condom, a special collection kit may be used. When producing at home, the sample must arrive to our lab within an hour from the time it leaves the body.  The sperm washing procedure will begin at your scheduled arrival time to our onsite laboratory, this part of the procedure will take approximately one hour as the lab needs to analyze and process the sample. When the specimen is ready, a speculum is inserted into the vagina and the washed sperm are inserted into the uterus via a small plastic catheter. It is a simple procedure and takes only a few minutes with minimal to no discomfort. When performed during a natural cycle, IUI is timed according to an LH (luteinizing hormone) surge, which precedes ovulation. When used in conjunction with ovulation induction, an injection of hCG (Novarel®, Ovidrel®) is generally used to trigger release of the egg, which allows optimal timing.


Success rates for artificial insemination are dependent mainly on the specific indication for which it is being used. When the sperm are inherently normal and only physical or psychological barriers to contact with the female partner exist, correctly timed insemination is most often successful, although not always on the first attempt. Where abnormalities of sperm production are present, success depends on the severity of the abnormality involved. With severely depressed counts, ovulation inducing agents are often given to the female partner in order to enhance the per cycle pregnancy rate. With the severest abnormalities, artificial insemination cannot be done and in vitro fertilization with intracytoplasmic sperm injection (ICSI) is required.

Obviously, the reproductive potential of the female partner is also crucial. Prior to beginning a program of artificial insemination, it is important to exclude any female factors that may also be obstructing conception and to discuss realistically the time frame in which pregnancy is expected to occur. There is no increased risk of congenital abnormalities in children born as a result of artificial insemination.
