Intrauterine insemination or IUI is commonly
known as artificial insemination. In this procedure, the sperm is placed into
the reproductive tract of the woman. This procedure increases the chances of
getting pregnant. The procedure of IUI is comprehensive. Read on to know about
the basics of IUI procedure.
Intrauterine insemination or IUI is an artificial
insemination procedure. This is basically human intrauterine insemination
through AIH or artificial
insemination by the husband of the woman who is impregnated. The process
involves the placing of the sperm within the uterus of the woman in order to
maximise her chance of getting
How this Happens?
In the IUI procedure, timing of the whole action is very
important in order to attain positive results. This is basically even more
important than the actual intercourse.
This is because during the intercourse, the sperm has to travel through the
cervical canal of the woman. There are number of glands in the cervix along
with the presence of mucous. This actually acts as a reservoir for the sperm
and it sustains itself. Then over a period of few days, this sperm is released
into the uterus.
Now, What Happens
During the IUI?
During IUI, the sperm is released into the uterus of the
woman and it does not remain viable for a few days as it was for the other
case. Thereby, it becomes essential that the sperm is inseminated at a time
that is nearest to the period of ovulation.
There is a certain manner in which this time is determined.
This is done with the aid of the ovulation
predictor kit. The kit measures the woman’s LH surge. The surge actually
attains its peak about twelve to twenty-four hours prior to the release of the
egg. A urine test is done on the woman for this purpose. If the result is
positive, the IUI procedure is conducted immediately on the following day.
The other method that helps in adjusting the desired timing
is by triggering the ovulation in an artificial manner. This is done through
the administration of the HCG injection. First an ultrasound is conducted in
order to determine the development of the eggs in the ovaries of the woman and
whether they are mature enough or not. After this time the ovulation occurs
within thirty-six hours. Say, if the HCG injection is administered in the evening,
the IUI procedure can be conducted after two days exactly.
How is the Sperm
While doing an IUI, one need not abstain from intercourse
and it is also important to note that sperm counts are variable in all men.
There also may not be a definite consistency in the sperm numbers in regard to
the frequency of ejaculation. The day when the ovulation kit gives a positive
result, the couple is suggested to go for an intercourse or it can also be
planned on the day that the woman receives the HCG triggering injection. The
desirable IUI timing can be attained under these circumstances.
Prior to the woman is scheduled for the IUI, the semen
sample needs to be collected in a sterile collection cup. Then the sperm is
liquefied inside the clinic’s incubator.
The Sperm Needs to be
Washed for IUI
Before placing the sperm into the uterus, it needs to be
prepared. The ejaculated fluid actually comprises of the seminal fluid and
sperm. The seminal fluid carries different hormones and chemicals. The
prostaglandin is one of the chemicals that can potentially cause problems in
IUI. The symptoms of IUI are that the woman can suffer from nausea, diarrhea,
fever, cramps and vomiting.
The separation of the sperm from the seminal fluid is called
sperm wash. After the semen is collected and liquefied, it actually becomes
thick. It is then mixed with sperm wash media and placed inside an instrument
called centrifuge. It is made to spin vigorously and that settles down the
sperm at the bottom as a small pellet. The seminal fluid that floats above is
discarded. A little more sperm wash media is added to it and mixed thoroughly.
This is the final specimen taken for insemination.
