精索静脉曲张手术后患者的管理策略

手术治疗精索静脉曲张在改善精液质量、提高配偶自然怀孕率和缓解局部疼痛症状中的作用已为多数医生所认同。随着手术方式的改进,越来越多的精索静脉曲张患者接受手术治疗,然而,临床对手术后患者的管理还重视不够。本文系统介绍了对精索静脉曲张手术后患者的疗效判断和后续治疗选择,包括观察随诊、非手术治疗方法和再手术。     

对比四维子宫输卵管超声造影与子宫输卵管造影评估输卵管通畅性效能:Meta分析

目的 采用Meta分析对比四维子宫输卵管超声造影（4D-HyCoSy）与子宫输卵管造影（HSG）评估输卵管通畅性的效能。方法 系统搜索PubMed、Cochrane Library、Embase、Web of Science、中国生物医学文献数据库、中国知网、万方医学网及维普数据库中建库至今有关4D-HyCoSy和/或HSG评估输卵管通畅性的文献。由2名研究人员依据纳入标准和排除标准筛选文献并提取信息；分别计算4D-HyCoSy和HSG评估输卵管通畅性的合并敏感度（SEN）、特异度（SPE）及诊断比值比（DOR），绘制综合受试者工作特征（SROC）曲线，获得曲线下面积（AUC），并以Medcalc 19.1.1统计软件比较AUC。结果 最终纳入19篇文献、1 358例疑似输卵管因素导致不孕患者，其中4篇同时采用4D-HyCoSy及HSG评估输卵管通畅性，10篇仅以4D-HyCoSy评估，5篇仅以HSG评估。Meta分析结果显示，4D-HyCoSy评估输卵管通畅性的合并SEN、SPE及DOR分别为0.92[95%CI（0.91，0.94）]、0.91[95%CI（0.89，0.93）]及115.06[95%CI（54.23，224.10）]；HSG评估输卵管通畅性的合并SEN、SPE及DOR分别为0.84[95%CI（0.81，0.87）]、0.80[95%CI（0.76，0.83）]及28.64[95%CI（10.08，81.35）]。4D-HyCoSy评估输卵管通畅性的AUC为0.98[95%CI（0.96，0.99）]，HSG为0.93[95%CI（0.90，0.95）]，差异有统计学意义（Z=6.97，P<0.01）。结论 4D-HyCoSy评估输卵管通畅性的效能高于HSG。     

Tratamiento empírico de la oligoastenoteratozoospermia idiopática

Male infertility accounts for 50% of the causes of infertile couples, being more than 30% of unknown etiology. In these cases, empiric treatment can be an option prior to the application of assisted reproduction techniques. Empiric treatment can be categorized as hormonal, such as gonadotropins, antiestrogens and aromatase inhibitors, and antioxidant, with vitamins, trace elements and carnitine, among others. Although scientifically acceptable evidence is limited due to the absence of large randomized and controlled clinical trials, recent systematic reviews and meta-analyses show that treatment with gonadotropins, antiestrogens and antioxidants increases pregnancy and live birth rates and improves seminal parameters. Empiric medical treatment for idiopathic infertility can be considered in specific cases in order to improve semen quality and spontaneous fertility.

精索静脉曲张患者精索静脉和外周血睾酮水平的对照研究

目的：探讨精索静脉血张患者血浆睾酮水平的变化及其机制。方法：对25例精索静脉曲张患者与22例腹股沟斜疝患者精索静脉和外周血睾酮水平进行对照研究。结果：精索静脉曲张组外周血睾酮浓度与腹股沟斜疝组无差别（P＞0．05），而精索静脉血睾酮浓度两组则有明显差异，精索静脉曲张组精索静脉血中睾酮浓度较腹股沟斜疝组低（P＜0．05）。结论：多种因素可影响外周血睾酮浓度，使其难以准确地反映睾丸分泌睾酮的实际水平，而精索静脉血中的睾酮浓度则能较为直接地反映睾丸的睾酮分泌能力。     

子宫内膜异位症并发不孕患者子宫内膜超微结构观察

目的：探讨子宫内膜异位症（EM）并发不孕患者围着床期子宫内膜的超微结构。方法：选择轻度子宫内膜异位症并不孕患者10例为研究组，已生育妇女7例作为对照组，选择在月经周期第19－22天刮取少量子宫内膜，进行扫描及透射电镜观察。结果：异位症患者围着床期子宫内膜出现超微结构改变，内膜表面腺体开口数少，纤毛再生不全，分泌细胞表面微绒毛极少，子宫内膜着床窗的形态学标记－细胞表面胞饮小泡减少 或缺失；胞质肿胀疏松，有的细胞出现核固醇，结论：异位症患者围着床期在位子宫内膜出现超微结构改变，细胞出现轻度变性，可能是其不孕的原因之一。     

Chromosomal Rearrangements in Three Infertile Men

Summary:  Three chromosomal rearrangements: a balanced reciprocal translocation, t(14;10) (q22;q13), a Y-autosome translocation, t(Y;16) (q11;p13) and a deleted Y chromosome, Yq- were detected among 100 infertile men. The autosomal translocation, associated with oligozoospermia was found to be familial with various effects on the female carriers and the proband's father. The patients with the chromosome Y abberations were found to be azoospermic and might have lost the genes necessary for normal sperma-togenesis.
Zusammenfassung:  Unter 100 infertilen Männern wurden drei Chromosomenneuan-ordnungen entdeckt: eine balancierte reziproke Translokation, t(14;10) (q22;q13), eine Y-autosome Translokation, t(Y;16) (q11;p13) und eine Deletion des Y-Chromosoms, Yq-. Die autosomale Translokation bei Oligozoospermie zeigte sich familiär mit verschiedenen Auswirkungen bei den weiblichen Überträgern und dem Vater des Probanden. Die Patien-ten mit chromosomalen Y-Aberrational wiesen eine Azoospermie auf und scheinen die zur normalen Spermatogenese notwendigen Gene verloren zu haben.     

Sperm chromatin integrity in young men with no experiences of infertility and men from idiopathic infertility couples

Damage to the genetic component of spermatozoa seems to play the main role in a majority of cases where current approaches fail to reveal the specific cause of male infertility. In this study, we compared semen quality in men assigned to two defined groups: men from couples with unexplained infertility – idiopathic infertility (A) and young men with no experiences of infertility (B). All samples were examined by standard ejaculate analysis and sperm chromatin structure assay (SCSA). Sperm chromatin damage was significantly higher in men from group A than in those from group B. Similar results were obtained by comparison of men from group A (all men were normozoospermic) with normozoospermic men from group B. According to these results, we can suppose that chromatin disorders may be the causal factor of subfertility or infertility in some of these men. No evidence for a strong association between chromatin disorders and standard parameters of ejaculates was found. We failed to confirm a relationship between smoking and sperm quality in men from any of the investigated groups. SCSA is a method that facilitates the identification of infertile men who otherwise show normal semen variables.
