男性乙肝病毒感染对精液质量及宫腔内人工授精的影响

<正>HBV感染呈世界性流行,全球约20亿人曾感染HBV,其中2.4亿人为慢性HBV感染者~([1])。我国是HBV感染大国,2006年全国乙型肝炎流行病学调查表明,1～59岁一般人群HBsAg携带率为7.18%~([2])。不少的男性HBV感染者存在不育,其中部分患者需行辅助生殖助孕治疗。目前的诊疗指南、文献关于男性HBV感染对宫腔内人工授精(IUI)的影响报道极少。本研究分析了男性HBV感染是否对精液质量、精液优化处理及IUI助孕结局

Effect of paracetamol on semen quality

Several published studies, both direct and indirect, have connected paracetamol, also named acetaminophen, a commonly used over‐the‐counter analgesic and antipyretic medication, with semen quality and male infertility, although as yet this connection is unclear. This review addresses the effect of paracetamol on semen quality and hence on male factor infertility. We searched the MEDLINE database from January 1980 through January 2017 for English‐language articles using the key words “paracetamol” and “acetaminophen” versus “sperm.” References from articles were used only if relevant. In summary, paracetamol, when used at high doses, appears to change semen quality, particularly sperm morphology, and hence its fertilising ability. Such effect of paracetamol on semen quality may occur by suppressing testosterone synthesis, inducing oxidative stress, provoking apoptosis of spermatocytes, reducing nitric oxide production and inhibiting prostaglandin synthesis. Further research, particularly clinical research, will be very important to confirm these effects.     

中国乙型肝炎和非肝炎男性间的精液质量和辅助生殖技术治疗结果的比较

本研究旨在确定乙型肝炎病毒（HBV）感染对精子质量和辅助生殖技术治疗结局的影响。分析2008年1月至2009年12月于浙江大学附属妇产科医院寻求辅助生育治疗的916例男性（457例乙型肝炎病毒携带者和459例阴性对照男性）的精液参数;将2004年1月至2009年12月期间的男性乙肝病毒携带的587个常规体外受精（In vitro fertilisation,IVF）周期和325个单精子卵细胞浆内注射（Intracytoplasmic sperm injection,ICSI）周期作为阳性观察组,根据取卵日期、女方年龄及ART受精方式通过统计软件以1：1比例匹配,设立夫妇双方均为HBsAg阴性的对照组（587个IVF周期,324个ICSI周期）,分析两组间的辅助生殖治疗结局。与对照组相比,乙肝携带者表现有较低的精液体积、精子总数以及较差的精子活动力和形态学表现（P〈0．05）;乙肝男性夫妇接受ICSI治疗后,双原核（2PN）受精率、优质胚胎率、胚胎着床率以及临床妊娠率均显著性降低俨〈0．05）;而两组病人间的IVF治疗结局差异无显著性（P〉0．05）。通过Logistic回归分析发现乙肝病毒感染作为一个独立的因素增加少弱精子症的发生以及降低ICSI治疗周期的胚胎着床率和临床妊娠率（P〈0．05）。我们的研究结果提示了男性乙型肝炎病毒感染与较差的精子质量和ICSI治疗结局有关,而对IVF治疗结局没有明显的影响。     

Effect of smoking on semen quality of infertile men in Shandong, China

Aim: To study the effect of smoking on the semen quality in infertile men in Shandong Province, China. Methods:Adult non-drinker males attending the infertility clinic, including 110 non-smokers and 191 smokers, were recruited forthe study. Sixty-one fertile, non-smoker and non-drinker males, who had one or more children, served as the controls.The smokers were divided into subgroups according to the amount and duration of smoking. Semen parameters (semenvolume and sperm density, viability, motility, and morphology) were examined and seminal plasma contents of Zn,Cu and superoxide dismutase (SOD) determined. Results: The semen volume and acidity, and the sperm density,viability and forward progression, as well as the seminal plasma contents of Zn, Cu and SOD were much lower in themedium, heavy and long-term smokers than in the non-smokers ( P < 0.01). The sperm density, viability and forwardprogression, and the seminal plasma Zn, Cu and SOD levels were negatively correlated with the amount and duration     

男性不育伴慢性病毒性肝炎患者血清和精液氧化应激水平及相关参数分析

目的:探讨男性不育伴慢性病毒性肝炎患者血清和精液丙二醛(MDA)、对氧磷酶-1(PON-1)水平及对精液相关参数的影响。方法:选择有生育力的男性健康对照组50例,男性不育组42例,男性不育伴慢性病毒性肝炎组45例,采用分光光度法测定血清和精浆MDA水平、PON-1活性,采用吖啶橙荧光染色法测定精子DNA碎片化指数(DFI)。结果:不育伴肝炎组血清和精浆MDA水平明显高于对照组和不育组(P<0.01和P<0.05),而PON-1活性明显低于对照组和不育组(P<0.01和P<0.05)。不育伴肝炎组精子活动率、精子存活率均明显低于对照组和不育组(P<0.01和P<0.05),而精子DFI明显高于对照组和不育组(P<0.01和P<0.05)。三组精子浓度无显著性差异(P>0.05);不育组与不育伴肝炎组精液WBC显著高于对照组(P<0.05)。男性不育伴慢性病毒性肝炎组精浆中的MDA水平、PON-1活性分别与血清中的MDA和PON-1呈显著正相关(r=0.57和0.48,P<0.01)。结论:病毒引起慢性活动性肝炎会使生殖系统氧化应激加强,加重对精子的损害,影响精子质量。     

Semen quality and infertility status can be identified through measures of oxidation–reduction potential

Standard analyses for evaluating semen quality require technical expertise and are interpretive in nature. Oxidative stress (OS) alters many of the semen parameters; thus, a measure of OS could be an indicator of semen quality. Static oxidation‐reduction potential (sORP) is a universal measure of OS traditionally used in environmental applications but is increasingly used in biomedical studies. sORP was measured to determine how well it associates with semen quality and if it differentiates semen from infertile patients and fertile donors. All study participants (Infertile, n = 365 and Fertile, n = 50) underwent standard semen analyses, and sORP was measured in unprocessed semen. In infertile patients, sORP increased with decreased total sperm number, motility and morphology. sORP values were higher in samples with abnormal quality (low number, motility and/or normal morphology) compared with those of normal quality. Infertile patients had higher sOPR values compared to fertile donors. A sORP cut‐off value of 1.38 mV/10⁶ sperm/ml can differentiate normal from abnormal semen samples, while a cut‐off value of 1.41 mV/10⁶ sperm/ml, can differentiate between infertile and fertile semen samples. In conclusion, sORP provides a quick and unbiased indicator of semen quality that can be a beneficial addition to semen analysis to determine semen quality and fertility status.     

Semen characteristics and inflammatory mediators in infertile men with different clinical diagnoses

This study was aimed at investigating whether semen characteristics in different clinical diagnoses of infertility are associated with PMN elastase, IL-6, IL-8, IL-1beta and TNFalpha levels detected in seminal plasma. Sixty-eight patients were divided into groups according to their clinical diagnosis: idiopathic infertility (group I), varicocele with infections (group II), varicocele (group III), infections (group IV), controls (group V). Physical examination and scrotal Eco-color Doppler was used to detect the varicocele. Patients with positive bacteriological semen analysis were considered as having an infection of the male reproductive tract. Samples were examined by light microscopy and transmission electron microscopy (TEM). TEM data were quantified with a mathematical formula furnishing a fertility index and the percentage of sperm apoptosis, immaturity and necrosis. PMN elastase/alpha1-PI complex levels were determined by ELISA and IL-6, IL-8, IL-1beta, TNFalpha by Bio-Plex Cytokine assay. Sperm concentration (I-II: p < 0.005; III-IV: p < 0.0001), motility (I-IV: p < 0.0001) and the fertility index (I: p < 0.005; II-IV: p < 0.0001) were significantly lower in the groups vs. controls, whereas sperm pathologies, except for apoptosis, were significantly higher in group I and apoptosis and necrosis were higher in group III. An increase in immaturity (p < 0.005) with a decrease in necrosis (p < 0.005) were observed in group III vs. group IV. Significantly higher levels of inflammatory mediators were detected in groups III and IV vs. controls. Despite a broad relationship among different inflammatory mediators, no correlation was found among them and the semen parameters, including indices from TEM analysis. In conclusion, patients with idiopathic infertility showed altered semen quality and normal levels of inflammatory mediators. Genitourinary infection and varicocele induced an inflammatory effect which could play a detrimental role in spermatogenesis, revealed by a decrease in sperm motility and the fertility index, concomitant with an increase in immaturity mainly in varicocele and necrosis in infection.
