To determine the relative concentration, motility, and viability of spermatozoa in the antegrade and retrograde portions of the ejaculate after electroejaculation in spinal cord injured men.
Retrospective.
University outpatient clinic providing tertiary care in reproductive rehabilitation.
The antegrade and retrograde portions of 22 ejaculates obtained from five spinal cord-injured men were analyzed for sperm density, mean sperm motility, and percentage of total motile and viable sperm yield.
The number of spermatozoa were uniformly distributed between the antegrade (54.4%) and retrograde (45.6%) ejaculates. However, of the total sperm yield in both compartments, 66.3% of the motile spermatozoa and 71% of the viable sperm were found in the antegrade compartment (P less than 0.05). Additionally, mean sperm motility was significantly higher in the antegrade ejaculate (P less than 0.05).
Significantly impaired sperm motility and viability are noted in the retrograde ejaculate. Efforts should therefore be directed to maximizing the antegrade portion of the electro-ejaculate and optimizing the technique of preserving functional sperm in the intravesical compartment.
确定脊髓损伤男性经电刺激射精后，射精顺行部分和逆行部分精子的相对浓度、活力和存活率。
回顾性研究。
提供生殖康复三级护理的大学门诊诊所。
对从5名脊髓损伤男性获取的22次射精的顺行部分和逆行部分进行分析，检测精子密度、平均精子活力以及总活动精子和存活精子的百分比。
精子数量在顺行射精（54.4%）和逆行射精（45.6%）之间均匀分布。然而，在两个部分的总精子产量中，66.3%的活动精子和71%的存活精子存在于顺行部分（P<0.05）。此外，顺行射精中的平均精子活力显著更高（P<0.05）。
逆行射精中精子活力和存活率明显受损。因此，应致力于使电刺激射精的顺行部分最大化，并优化膀胱内保存功能性精子的技术。
