Abstract

PURPOSE: To determine whether postwashed total progressively motile sperm count (TPMSC) obtained by CASA estimates could predict positive pregnancy test result in non-donor IUI cycles.

METHODS: Six thousand eight hundred and seventy one (6,871) IUI cycles with non-donor semen were retrospectively analyzed. Patient, cycle characteristics and prewashed and postwashed semen parameters were included in analysis. The main outcome measure was the positive pregnancy test result.

RESULTS: The pregnancy rate per cycle (PR/cycle) when postwashed TPMSC is between 0-0.5 million, 0.51-1 million, 1.01-5 million, 5.01-10 million and greater than 10 million were 8.1% (42/520), 14.4 % (41/285), 16.1% (237/1,469), 18.4% (193/1,046) and 18.8% (668/3,551) respectively. The predicted odd of positive pregnancy result is statistically significantly higher when TPMSC is >0.51 million compared to the TPMSC of <0.51 million (OR = 1.68, 95% CI: 1.04-2.71). The predicted odd of positive pregnancy result is greatest when TPMSC is at least 5 million (OR = 2, 95% CI: 1.38 to 2.9).

CONCLUSION: TPMSC is an independent predictor of pregnancy test result and TPMSC of half million or greater is adequate to achieve statistically similar pregnancy test results after non-donor IUI cycles.
