Predictive Factors For Intrauterine Insemination Success: Analysis Of Semen Parameters Affecting Outcome

Objectives: The aim of this study was to determine factors influencing the pregnancy rate following intrauterine insemination (IUI) and to evaluate sperm parameters affecting outcome. Patients and methods: A retrospective analysis of 223 IUI cycles with ovarian stimulation by clomiphene citrate and/or gonadotropins was performed. Clinical pregnancy rates were analyzed according to all variables such as the womans age, the number of the attempt, the spermogram characteristics, the sperm morphology after preparation, and the total motile spermatozoa count. Results: A total of 20 clinical pregnancies were obtained for a pregnancy rate per cycle (PR) of 9.2%. For patients who are under the age of 37 the pregnancy rate per cycle was 11.17% and no pregnancies occurred for the other patients who are above the age of 37(p 80 %;( P<0.0001).The PR was significantly higher with total motile spermatozoa count inseminated "e5 x 106 Compared to only <5 x
