Total and ionized calcium (Ca2+) levels of seminal fluid were assessed in 75 semen samples obtained from infertile patients and fertile patients referred to our clinic with different complaints. Patients who showed only motility disorders on sperm analysis were include into the study program. Forty-five patients showing hypomotility (motility < 60%) and 30 patients with normal motility (motility > or = 60%) on sperm analysis were evaluated comparatively. No significant difference was observed in the seminal fluid concentration of total calcium, regardless of spermatozoa motility immediately after ejaculation. However, the seminal fluid of men with hypomotility exhibited a significantly lower Ca2+ concentration (p < 0.05) when compared with that of men with normal motility. A significant difference was observed in the seminal fluid Ca2+/total calcium rate (p < 0.05) when compared with that of men with normal motility. Further, spermatozoa from men with hypomotility exhibited both a significantly lower progression rate and sperm count. Our study suggests a direct relationship between Ca2+ and sperm motility.
对从因各种不同病症前来我们诊所就诊的不育患者和可育患者获取的75份精液样本，评估了精液中的总钙和离子钙（Ca2+）水平。精子分析仅显示活力障碍的患者被纳入研究项目。对45例精子活力低下（活力<60%）和30例精子活力正常（活力≥60%）的患者进行了精子分析，并进行了比较评估。射精后立即检测，无论精子活力如何，精液中总钙浓度均未观察到显著差异。然而，与精子活力正常的男性相比，精子活力低下的男性精液中Ca2+浓度显著降低（p<0.05）。与精子活力正常的男性相比，精液中Ca2+/总钙比率存在显著差异（p<0.05）。此外，精子活力低下的男性精子的前进速率和精子计数均显著降低。我们的研究表明Ca2+与精子活力之间存在直接关系。
