Factors that influence the outcome of the intrauterine insemination with husband's sperm.

A retrospective analysis was undertaken in 160 intrauterine insemination with husband's sperm (IUIH) cycles, performed in 45 couples. The male factor represented the main indication (80%). Women who conceived had a lower duration of infertility (4.4 years +/- 3.0 vs 7.7 +/- 2.98). A significantly and pardoxically lower motility (3+ and 2+) was observed in raw specimens within conceptional cycles. However in prepared specimens in conceptional cycles the percentage of motility 3+ and 2+ was significantly increased (80.6% +/- 8.1 versus 70.7% +/- 20.2). The most significant difference was found in regard to a better response to preparation among conceptional cycles, expressed as the percentual increase in motility 3+ and 2+ (55.6% +/- 3.9 vs 41.3% +/- 19.4).
