摘　　要：目的探索现阶段正常生育力的健康男性精液的各项参数及其相互关系.方法采用WHO最新推荐的方法,对广东某市农村312例具有生育力的健康志愿者进行精液检测分析.结果(1)具有(a+b)级活动力精子率(60.63±11.76)%;(2)精子存活率(80.89±10.49)%;(3)精子密度(60.09±30.25)×106/ml;(4)不同年龄组间(a+b)级活动力精子、精子存活率及精子密度的参数比较,无显著差异(P＞0.05);(5)禁欲时间与(a+b)级活动力精子、精子存活率间的关系呈负相关(P＜0.05),与精子密度间的关系呈正相关(P＜0.01),但不同禁欲时间组间与(a+b)级活动力精子、精子存活率及精子密度的比较,无显著差异(P＞0.05);(6)精子密度与(a+b)级活动力精子和精子存活率无明显的相关关系(P＞0.05),且(a+b)级活动力精子和精子存活率始终保持着平衡状态,并在50%以上.结论(1)(a+b)级活动力精子＞50%、精子存活率＞50%,即使精子密度偏低或＜20×106/ml仍不影响正常男性的生育能力;(2)(a+b)级活动力精子、精子存活率以及精子密度与年龄(20～45岁)无关;(3)精子密度的高低对(a+b)级活动力精子和精子存活率无明显影响.Objective To explore semen parameters and their intercorrelation in healthy men fertile at present stage. Methods The semen samples of 312 volunteers from countryside in Guangdong were measured and analyzed with the methods recommended newly by the WHO. Results (1) the percentage of sperm motility with grade a + b was 60.63±11.76. (2) The percentage of sperm vitality was 80.89±10.49. (3) Sperm density was (60.09±30.25)10 6 /ml. (4) There were not significant differences in the percentage of sperm motility with grade a+b, sperm vitality and sperm density among all age-groups. (5) The percentage of sperm motility with grade a+b and sperm vitality were negatively correlated with the number of days of sexual abstinence (P<0.05); while sperm density was positively correlated with the number of days of sexual abstinence (P<0.01). However, no significant differences were found in the percentage of sperm motility with grade a+b, sperm vitality and sperm density among groups with different sexual abstinence days. (6) There were no significant differences among the percentage of sperm motility with grade a+b, sperm vitality and sperm density (P<0. 05); the percentage of sperm motility with grade a+b and sperm vitality were kept in the stable status and highly than 50%. Conclusion (1) In case sperm density is lower than 20×10 6 /ml, if sperm motility with grade a+b and sperm vitality are higher than 50%, fertility of men could not be influenced. (2) There were no correlations between percentage of sperm motility with grade a+b, and sperm vitality and sperm density with age of men (20~45). (3) The percentage of sperm motility with grade a+b and sperm vitality were not be influenced by sperm density at definite ranges.
