In fact, IUI or Intrauterine insemination is a procedure in which women take oral medication for ovarian stimulation or injection for ovarian stimulation together with selecting qualified sperm. Then, injecting sperm directly into the uterus.
For female sterilization, both fallopian tubes are cut and sealed. Therefore, when we inject sperm into the deepest area which is the uterus. Sperm will move through fallopian tubes in order to fertilize.
However, there is a lack of important parts which are fallopian tubes. In explanation, sperm will not be able to move into the uterus without fallopian tubes in sterile women. Therefore, sterile women are not able to enter IUI program.
In case sterile women would like to conceive, there are 2 solutions which are to reverse sterilization or to enter ICSI program.
For male sterilization, it is a permanent birth control by cutting and sealing the tubes that carry a man’s sperm.
In fact, men can also reverse sterilization but the success rate is not high since the tubes are tiny. Even though the sperm can be collected, the sperm count will not be enough to inject into the uterus. Sterile men are not able to enter IUI program.
Therefore, apart from sterilization reversal, there is another option which is ICSI program together with PESA. This is a method in which a needle is placed directly into the epididymis. Then, collect sperm for ICSI procedure.
This method is appropriate for sterile men who wish to have babies. IVF technology is more recommended than IUI program.
