IUI (artificial insemination) success rates


IUI success rates vary, largely depending on the reason that they are being performed.  A more complete discussion of the reasons for considering an IUI is contained in a different section of this Complete Guide to Understanding IUI.


When IUI is performed during cycles using ovulation induction medication, several mature eggs may be released at ovulation and the success rates are somewhat greater than during a natural cycle.  The success rate for medicated cycles with IUI may be as high as 30% per cycle.


When IUI is performed for abnormal sperm quality, the placement of sperm directly into the uterus next to the fallopian tubes often improves the sperm’s ability to fertilize an egg.  Success rates depend on the severity of the male factor, but may be as high as a normal fertile couple, which is about 20-25% per cycle.


When IUI is performed for hostile cervical mucus, the delivery of sperm above the cervix into the uterus at ovulation should completely avoid the cervical mucus.  If the mucus is the only fertility issue for the couple, then they should have a success rate similar to a normal fertile couple (20-25% per cycle).


When IUI is performed for couples that cannot complete sexual intercourse, the success rate should be that of a normal fertile couple (about 20-25% per cycle) if there are no other fertility issues.


When IUI is performed for infertile couples with no formal fertility testing it is impossible to predict success rates since no specific abnormality has been identified.  If the couple has an undiagnosed male factor or an undiagnosed mucus factor as a sole reason for the fertility problem, then the IUI should restore success to the chances as described above.
