Abstract:
Objective To probe into the application of PureceptionTM gradient centrifugation technique for sperm separation in artificial insemination by husband (AIH) .Methods Prepare the semen by PureceptionTM gradient centrifugation technique ,and used for 1360 AIH cycles in 672 infertile couples .Results After preparing the semen by PureceptionTM gradient centrifugation technique ,the sperm concentration was increased from (54 .86 ± 26 .03) × 106/mL to (63 .89 ± 34 .40) × 106/mL ,the rate of PR sperm was increased from (32 .47 ± 9 .31)% to (69 .78 ± 5 .10) ,the differences were both statistically significant (P<0 .05) .the recovery rate of PR sperm was (34 .08 ± 3 .95)% .672 infertile couples received 1360 AIH cycles ,and the clinical pregnance rate was 16 .62% (226/1360) .According to the sperm concentration before preparing the semen ,the cycles were divided into 3 groups :≥15 × 106/mL (GroupⅠ) ,(≥10 ,<15)× 106/mL (GroupⅡ ) and <10 × 106/mL (Group Ⅲ ) ,the clinical pregnancy rates were 17 .13% ,16 .05% and 4 .26% ,respectively ,Group Ⅲ was significantly lower than the other two groups (P<0 .05);According to the rate of PR sperm ,the cycles were divided into 3 groups:≥32% (Group A) ,(≥10 ,<32)% (Group B) and <10% (Group C) , the clinical pregnancy rates were 17 .53% ,16 .55% and 4 .65% ,respectively ,Group C was significantly lower than the other two groups (P<0 .05) .According to the number of PR sperm after preparing the semen ,the cycles were divided into 2 groups:≥10 × 106 and <10 × 106 ,the clinical pregnancy rates were 17 .33% and 10 .22% ,the difference was statistically significant (P<0 .05) . Conclusion PureceptionTM gradient centrifugation technique is a better way for sperm separation ,and the clinical pregnance rate is satisfactory when it is used in AIH .When the sperm concentration is ≥10 × 106/mL and the rate of PR sperm is ≥10% before pre‐paring the semen ,and the number of PR sperm is ≥10 × 106 after preparing the semen ,patients will get a more ideal pregnancy rate .
