Objective: the purpose of this study was to determine the impact of post-wash total progressive motile sperm count (tpmsc) and semen volume on pregnancy outcomes in intrauterine insemination (iui) cycles. material and methods: the retrospective study included a total of 156 cycles (141 couples) and was performed in our center over a 24-month period. the semen parameters were recorded for each man and each insemination. the semen samples were re-evaluated after the preparation process. post-wash tpmsc values were divided into four groups; group 1: <1×106; group 2: 1-4.9×106; group 3: 5-9.9×106; group 4: 10×106 and >10×106. post-wash inseminated semen volume was divided into three groups; group 1: 0.3 ml; group 2: 0.4 ml; group 3: 0.5 ml. the effect of post-wash total progressive motile sperm and semen volume on pregnancy outcomes was evaluated. results: the pregnancy rates per cycle and per couple were 27.56% and 30.49%,respectively. there was not a significant relationship between the inseminated semen volume and pregnancy rate (p>0.05). however,a significant linear-by-linear association was documented between the tpmsc and pregnancy rate (p=0.042). conclusion: our findings suggest that the post-wash inseminated semen volume should be between 0.3-0.5 ml. an average post-wash total motile sperm count of 10×106 may be a useful threshold value for iui success,but more studies are needed to determine a cut-off value for tpmsc. © 2013 by the turkish-german gynecological education and research foundation.
