摘要
目的探讨18年来广东人精液质量是否下降。方法记录2002～2005年间705例志愿供精者的年龄、精液量、精子密度、精子总数、精子活动率的结果(A组),与1985年联合国人口基金课题(WHO 85010) 114例正常生育者数据(B组)和1985年香港发表的1239例(其中82例已知有生育孩子)中国人数据(C组)比较。数据用μ检验,并用SPSS程序作t测验。结果A组年龄为(27．4±5．4)岁,显著小于C组(29±4．9)岁。但是,A组精液量(3．1 2±1．46)ml,精子密度(101．78±73．2)×106/ml,精子总数(317．27±275．2)×106,精子活动率(73．17±20．56)％显著高于C组。已生育孩子的男子数据表明:A组(n=154)精液量(3．32±1．54)ml,精子活动率(73．56±22．04)％显著高于B组和C组;A组精子密度(112．28±75．89)×106／ml和精子总数(376．75±318．41)×106显著高于C组,但与B组没有显著差异。A组年龄(31．64±6．0)岁明显低于C组,但与B组没有差异。结论2005年的精子密度和精子总数没有变化,但精液量和精子活动率显著高于18年前的相应的参数。目前的数据提示:与18年前相比,广东人的精液参数没有减低。
ObJective To determine whether semen parameters has declined in Guangdongese after 18 years. Methods Age and semen parameters including semen volume, sperm density, total sperm count, sperm motility in 2005 （group A） from 705 semen donors were recorded. Same parameters from 114 fertile Guangdongese （ project of UNFPA 85010 in 1985） in same laboratory （group B） and 1239 Chinese （82 with children） from HongKong in 1985 （group C） were compared with Group A. Data was analyzed using u-test and SPSS program （t-test）. Results The age of subjects （27.4±5.4） years from group A （n=705） was significantly lower than group C. However, the semen volume （3.12±1.46） ml, sperm density （101.78±73.2 million/ml）, total sperm count （317.27±275.2） million and sperm motility （73.17±20.56）% from group A were significantly higher than that of from group C （n=1239）. Another results of fertile men with children showed that the semen volume （3.32±1.54）ml, sperm motility （73.56±22.04）% from group A （n=154） were significantly higher than that from group C （n=82） and Group B （n=114）. Sperm density （112.28±75.89）million/ml and total sperm count （376.75±318.41）million from group A were significant higher than that from group C, but not with Group B. The age of subjects from group A （31.64±6.04）years was significantly lower than that of from group C, but not with group B. Conclusion Some of semen parameters, such as semen volume, and sperm motility, were significantly higher than that from 18 yeats ago. There was no decline in semen parameters from Guangdongese when comparing with 18 years ago.
