Routine semen parameters and the pregnancy rate of intrauterine insemination

Objective To study the relationship of routine semen parameters and the pregnancy rate of intrauterine insemination(IUI).Methods 178 cycles of 125 patients with IUI were retrospectively analyzed,according to the density of sperm before washed,the sperm morphology before washed and the sperm count before washed,they were divided into two groups:pregnant group and non-pregnant group.Results In 125 cases of 178 treatment cycles,34 cases were pregnant,with success rate of 19.10% for each cycle of treatment(34 /178) and the clinical pregnancy rate of 27.20% pre patient(34 /125).There was no difference in the routine semen parameters between two groups.The pregnancy rate was obviously decreased when the sperm count 100×10 6 or sperm density was 20×10 6 /ml(P0.05),but was not affected by sperm morphology.Conclusion In order to have a reasonable success rate of IUI treatment,the sperm count should be ≥100×10 6 or the sperm density≥20×10 6 /ml.
