精液白细胞与不育症之间关系探讨

目的以瑞-姬染色方法,油镜精细观察,区分精液中生精细胞与白细胞,探讨精液白细胞的检出率与不育症之间关系,以提供临床参考。方法293例精液采用瑞-姬染色,油镜进行白细胞及其他细胞形态分类,并进行统计处理。结果293例不育症精液中检出白细胞阳性136例占46.4%;阴性157例占53.6%。年度精液白细胞阳性率1990年为13.8%;1993年为21.5%;1997年为34.1%;2006年为46.4%,说明有逐渐增加趋势。对2006年136例精液白细胞数量分布统计,以≤5个者最多占70.6%;6~20个占8.9%;21~40个占3.4%;>40个占1.3%。1~4个组与5~9个组、>20个组比较,有显著差异(P<0.001)。56例精液与前列腺液进行白细胞对照观察,两者均有白细胞者为48.2%(27/56)。精液中非生精细胞检出率,以前列腺上皮细胞最高为27.3%;其次是吞噬细胞为23.5%;再次是淋巴细胞为10.8%;支持细胞和间质细胞均为8.1%。结论精液白细胞有逐年增加趋势,影响精液质量造成不育症,实验室应认真检测,以油镜观察≤5个者,可考虑来源于精液;>5个者应检查前列腺,临床应注意其来源,对症治疗。

Investigation on the relationship between leukocytes in semen and infertility

Objective:The high power microscopic examination of fresh semen sample often mistakes the spermatogenic cells as leukocytes.We here used staining method and oil lens to observe the samples carefully for confirming the leukocytes in semen and explore the relationship between the detection rate of leukocyte in semen and infertility,hopefully providing the clinic parameter.Method: The semen samples from 293 men with infertility were dyed with the wright's-Giemsa's stain and leukocytes and other types of cells ...
