  sperm morphological
Detailed studies of sperm morphological abnormalities were carried out on 12 Zebu×Friesian crossbred bulls used in a study of the effects of trypanosomosis.
      
All the bulls initially had very low sperm morphological abnormalities that were within acceptable limits for fertile animals.
      
All the infected bulls developed sperm morphological abnormalities of more than a mean of 40.0% from the 4th week after infection until the end of the investigation and were considered unfit for breeding.
      
At 7 weeks post-infection (PI) until the end of the study (12 weeks PI), the controls had a mean of less than 5% sperm morphological defects, while the infected bulls had 100%.
      
Mean percentage values of sperm morphological defects throughout the duration of the investigation for control bulls were low and within the normal range for fertile bulls.

Induction of possible male sterility in laboratory rats by gossypol was examined by microscopic observations on sperm motility, sperm morphology following silver staining, and meiosis. The rats were force-fed with gossypol acetate once with 400mg/kg body weight. In a span of 2-5 weeks post-feeding, a marked reduction of sperm motility was observed with a concurrent increase of abnormal spermatozoa Silver staining of the spermatozoa showed various tail abnormalities, including disrupted connecting piece, bent...

Induction of possible male sterility in laboratory rats by gossypol was examined by microscopic observations on sperm motility, sperm morphology following silver staining, and meiosis. The rats were force-fed with gossypol acetate once with 400mg/kg body weight. In a span of 2-5 weeks post-feeding, a marked reduction of sperm motility was observed with a concurrent increase of abnormal spermatozoa Silver staining of the spermatozoa showed various tail abnormalities, including disrupted connecting piece, bent tails, looped tails, and cracked midpiece, Sperm head structure appeared to be not affected. Beginning 6 weeks post-feeding, there was a complete recovery. Short-term in vitro experiments showed similar but weaker response. In all samples, histologieal sections and cytogenetic preparations of testes revealed no abnormalities in the activity and normally of meiotic divisions. In animals 2-4 weeks after feeding with gossypol, no argentophilic accessary structures in developing mammalian spermatids were observed.

大白鼠喂服棉酚后,对其附睾精子活动力、精子形态学及睾丸减数分裂制片进行银染观察。对大白鼠一次性喂服大剂量棉酚(400 mg/kg体重),喂后2~5周,精子活动力明显降低,不正常精子频率增加,附睾精子银染显示精子尾部有损伤,包括精子头尾分离、尾部成圈、精子尾部中段部分区域损伤,但精子头部形态正常。服药6周后,附睾精子全部恢复正常。短期体外孵育实验,显似类似结果,但较轻微。喂服棉酚2~4周期间,不同发育阶段精子细胞的嗜银结构消失。实验组睾丸组织切片及睾丸减数分裂制备片,并无异常发现。

In this study, thirty fertile and infertile semen sample were used. The acrosomal enzymes of spermatozoa were demonstrated by using substrate film method together with morphological analysis and MEP, The results showed that the site of protease or hyaluronidase activity appeared around the sperm head as clear areas or halos. In infertile men, the percentage of reaction and the average diameter of reaction area of the protease were decreased significantly (p<0.01), but the hyaluronidase did not show marked changes...

In this study, thirty fertile and infertile semen sample were used. The acrosomal enzymes of spermatozoa were demonstrated by using substrate film method together with morphological analysis and MEP, The results showed that the site of protease or hyaluronidase activity appeared around the sperm head as clear areas or halos. In infertile men, the percentage of reaction and the average diameter of reaction area of the protease were decreased significantly (p<0.01), but the hyaluronidase did not show marked changes (p<0.05). The rate of abnormal sperm of infertile men was higher than that of fertile men. The average velocity of sperm movement was similar in the infertile and fertile men, but the percentage of forward progression spermatozoa was much lower in the former. The relation between acrosomal enzymes, abnormal morphology and sperm motility was discussed.

本研究应用健康人和不育症患者的精液各30人份,用底物膜技术检测精子顶体酶,同时进行精子形态学和多次曝光摄片分析。结果表明,在精子头部周围,顶体蛋白酶和透明质酸酶活性区域呈现亮区或晕。不育症患者顶体蛋白酶反应率和反应区的平均直径显著降低(P<0.01),但是透明质酸酶无明显变化(P>0.05).不育症患者精子畸形率高于健康人.不育症患者和健康人精子运动平均速度相似,但直线运动方式的精子在前者明显减少.本文对精子的顶体酶、形态异常和运动等相互关系作了讨论.

This aetiological study was carried out in 50 cases of clinical unexplained infertility and 32 proven fertile control men.Sperm morphology,motility, WGA receptor value of sperm membrane and antisperm antibodies in sera, seminal plasma and on sperm membrane were determined.Specimens of semen and sera were collected in the morning ahd sent to the laboratory immediately for processing and detections of morphological abnormalies,sperm movement characteristics,membrane WGA receptors and antisperm antibodies and their titers.Results indicate that the defects in sperm morphology and sperm motility arc two important influential factors of fertilizing capacity of infertile patients,while sperm membrane WGA recepters show no significant difference between the control and unexplained infertie groups,and antibody titers of almost all 12 infertile couples with antibodies in sera are≤1:32.Through the application of time-exposure photomicrographic technipue,in 14 parameters of sperm motility,6 parameters recveal significant differences between the control and infertile group,pcrcentage of morphological abnormal sperm was negatively correlated with 2 of the 6 above mentioned parameters(P<0.01).lt was found that multiple defecis in sperm morphology,motility or immunology were very common in some couples with unexplained infertility.The importance of normal morpholgy and physiology in maintaining fertility and the aetiololgical meaning of their defects was discussed.

应用定时曝光显微摄影法(TEP)对32例有生育力的正常男性与50例不明原因不育症患者进行精子运动特征的客观评价与分析,并同时进行精子形态学检查、精子膜 WGA 受体值测定和血清、精浆、精子膜抗精子抗体的免疫学检测。病因学研究表明,单纯由免疫因素所致不育的患者所占比例很小;不育组在精子膜 WGA 受体值上与正常对照组无显著差异;而在精子形态与运动功能方面有显著差异;导致某些不明原因不育症患者不育的因素可能是单一因素,也可能是二种以上对生育有影响的因素。TEP 是客观.定量评价精子运幼功能的一种较理想的方法,可检测出用常规精子活力评价方法难以查出的精子运动功能缺陷。在14项精子运动特征指标中,有6项指标在对照与不育组间存在显著差异,其中2项与精子畸形率的增加存在显著的负相关性(P<0.01)。
