摘要
目的探讨海岛不育症患者海产品摄入量对精液质量的影响,为男性不育症患者的诊治提供更多、更有价值的信息。方法采用自行编制的调查表对228例不育症男性患者进行问卷调查及精液常规分析。结果精液质量正常94例,异常134例;精子密度(25.39±16.21)×106/ml,正常形态的精子比例(57.40±17.45)%,异常形态的精子比例(40.73±7.23)%,精子活动度a级(35.16±15.85)%、b级(9.38±4.15)%、c级(13.07±6.89)%、d级(32.57±13.78)%。食物结构中摄入较多海产品者b级、d级精子的比例分别为(10.46±2.86)%和(40.41±6.94)%,与海产品摄入一般及较少或无者比较,差异有显著性意义(均P<0.05)。海产品不同烹调方法对精液质量的影响无显著性差异(均P>0.05)。结论不育症患者精液质量异常比例较大,过多摄入海产品对精液质量有影响。需对不孕症患者做好饮食指导,控制海产品的摄入,合理营养,倡导平衡膳食。
Objective To find out whether the amount of seafood intake play a role in quality of semen in infertile males and to provide more valuable information for treatment of male infertility. Methods A total of 228 infertile males were investigated by using a self-designed questionnaire and their semen samples were harvested for laboratory analysis. Results Ninety-four cases were found to have normal semen, while 134 abmormal one. Laboratory results showed that the sperm density was （25.39 ± 16.21）× 10^6/ml, the proportions of normally-shaped sperms and abnormally-shaped ones were （57.40 ± 17.45） %, （40.73± 7.23） % respectively; the percentages of sperm motility graded a, b, c, and d respectively were （35.16±15.85）%, （9.38±4.15） %, （13.07±6.89）%, （32.57± 13.78）%. Among participants who reported abundant seafood intake, the percentage of Grade b sperms was （10. 46 ±2. 86）%, with the percentages Grade d sperms being （40.41±6.94） %. Compared with those who reported moderate or scant intake of seafood, significant differences were found between the percentages （P〈 0. 05 for all）. Different ways of cooking showed no significant impact on quality of semen（P〉0.05 for all）. Conclusion Infertile males were prone to have poor-quality semen. Excessive intake of seafood affected the quality of semen. Dietary guidance should be targeted to infertile males so as to control their seafood intake and promote balanced nutrition level.
