    Pregnancy rates after intrauterine insemination (IUI) varies greatly. We aimed to identify pre and post processing semen analysis parameters that may be predictive of successful pregnancy in couples undergoing IUI.


    A retrospective study of the records of all couples underwent IUI for a 2 year period at our infertility center. Different characteristics of female subjects, pre and post processing semen parameters and treatment parameters were compared statistically.


    Thirty-two clinical pregnancies followed 526 IUI cycles in 294 couples, for a clinical pregnancy rate of 6.1% per cycle and a 10.9% per couple. The mean age of the women at IUI was 31.14 ? 6 years (range 19-45 years). Neither maternal age, body mass index, number of mature follicles, maximum day 3 follicle stimulating hormone level, presence or absence of previous children, number of previous miscarriages, nor prewash semen parameters had any impact on pregnancy rate post IUI. Postwash total motile sperm count (TMSC) (p = .027) and number of cycles (p = .042) were independent predictors of successful pregnancy after IUI.


    A postwash TMSC of 5 million sperm or more is significantly associated with a high pregnancy rate. After ruling out medically or surgically correctable male factors that may contribute to infertility, we recommend including a pretreatment sperm processing during routine male fertility work up for proper patient counseling and direction to the suitable assisted reproduction technique.
