ARTIFICIAL INSEMINATION PROCEDURES
The 1980`s was a time when Artificial Insemination was a popular form of IVF treatment as there are no surgical procedures, and it can be conducted in a clinic.
Firstly we before we carry out the procedures we must determine whether the female is a viable candidate for insemination, as she will need to be diagnosed with infertility problems and have unblocked fallopian tubes, as well as having a viable sperm sample/
There are different treatment options open to couples:
INTERCERVICAL INSEMINATION (ICI)
This is the easiest procedure in which fresh or thawed sperm is injected directly into the cervix. There ıs no need for the sperm to be washed or for the sperm to be prepared in a laboratory. The procedure is performed by following the natural ovulation period and injecting at the right time. The success of treatment carries the same percentage as couples engaging in sexual intercourse.
INTRAUTERINE INSEMINATION (IUI)
This procedure is the most commonly used method. Sperm is washed and prepared accordingly in a laboratory. When the sperm values reach the required concentration, they are then injected into the uterus with a special solution. The sperm is left to swim through the fallopian to then fertilise with the egg. This procedure may require medication to encourage the development of eggs and or to control ovulation with the aid of an HCG before it can be carried out.
INTRAUTERINE TUBOPERITONEAL INSEMINATION (IUTPI)
Intrauterine tuboperitoneal insemination (IUTPI) is when washed sperm is injected into both the uterus and fallopian tubes.
INTRATUBAL INSEMINATION (ITI)
Intratubal insemination (ITI) is when sperm is inserted into the fallopian tubes. This is not a preferred method as when compared to the others it shows no real advantages and is outdated.
The success of insemination is dependant not only on the females’ age, the health of the couple and sperm quality.
Looking at the general success rates of insemination, they are shown to be:
ICI: 10-15 %
In total of 6 treatments, the success shows to between 60-70%
The pregnancy rate also depends on the total sperm count (TSC) and more so the total lıve sperm count (TLSC).

SPERM PREPARATION FOR ARTIFICAIL INSEMINATION
All insemination procedures prepare sperm in the same practice. It is recommended that the minimum count of live sperm is 5 million and a concentration of 0.5 mls.
The preparation of the sperm produced is analysed in the laboratory where the sperm count and movement is determined. The sperm is then washed in a general solution to wash away any external fluids. During this process, the dead sperm is removed. After the washing process, the sperm count and movement is again monıtored. The prepared sperm is placed into a catheter and then injected directly into the uterus.
