据世界卫生组织公布的数字,全球不育症患者人数已达8 000万~1.1亿[1],而据中国人口协会2009年发布的《中国不孕不育现状调查报告》显示,中国约有10% ~ 15%的配偶存在生育障碍,其中50%的致病因素与男性有关[2],生育形势不容乐观.据世界卫生组织标准,夫妻婚后同居≥1年,未采取避孕措施,由于男方原因造成女方不孕者称为男性不育[3].导致男性不育的原因很多,如精液异常、精子运送受阻、内分泌因素等.基于中国约13%的国土面积存在环境污染的现状,以及相对于其他哺乳动物而言,男性生殖系统更易遭受生殖毒性物质损害的特点,环境污染可能是导致人类精子质量下降最主要的外在因素[4].现将环境污染(重金属污染)对男(雄)性生殖的影响作一综述. 相似文献

抗苗勒管激素(anti-Mullerian hormone,AMH),又名苗勒管抑制素(Mullerian inhibiting substance,MIS),最早发现于男性胎儿,因抑制其苗勒管的发育而命名,对男性性分化具有重要作用。目前研究发现AMH在男性生殖相关领域有更加广泛的临床应用,主要体现在5个方面:(1)诊断两性畸形患者是否存在男性性腺,血清AMH比Y染色体敏感度更高,且是青春期评估睾丸功能较好的标志物;(2)与血清AMH水平比较,精浆AMH与睾丸生精功能显著相关,与精液质量呈正相关,是鉴别梗阻性、非梗阻性无精子症特异性较高的标志物;(3)精浆AMH是目前预测严重少、弱精子症患者精液冷冻-复苏率较好的指标;(4)精浆AMH水平可预测重组人卵泡刺激素(rh FSH)治疗特发性少、弱精子症的疗效;(5)对生育期需接受放化疗的男性肿瘤患者生育力的评估,精浆AMH是目前特异性最高的生物标志物。 相似文献

目前新型冠状病毒感染的机制已经明确,男性生殖系统也可能是新型冠状病毒感染的目标。男性感染新型冠状病毒后,可能会出现暂时性的精液量减少、精子浓度降低、精子数量减少、精子活力降低、正常形态精子百分率降低及精子DNA碎片率增加等精液检测指标的变化,影响男性的精液质量、降低男性的生育能力,引发这一系列变化的机制可能包括了睾丸炎症、过度免疫、细胞因子风暴、内分泌功能受损和发热等,男性精液中是否存在新型冠状病毒还需要进一步的研究检测确定。综述新型冠状病毒感染对男性精液检测指标的具体影响和作用机制,为备孕期夫妇在感染新型冠状病毒后的相关治疗和辅助生殖治疗的受精时机选择提供参考。 相似文献

Klinefelter's syndrome is the most common genetic disorder in which there is at least one extra X chromosome. Males normally have an X chromosome and a Y chromosome (XY). But males who have Klinefelter syndrome have an extra X chromosome (XXY), giving them a total of 47 instead of the normal 46 chromosomes. Sex chromosome abnormalities are more frequently associated with male infertility. The prevalence of XXYs has risen from 1.09 to 1.72 per 1 000 male births. A patient attended to fertility and genetic clinic, during the clinical diagnosis we found the following complaints of loss of secondary sexual characteristics and infertility. Physical examination revealed breast development, thin built, small size testes, and absence of beard and pubic hairs. Karyotype and biochemical analysis were performed to detect chromosomal abnormality as well as hormonal level to confirm the diagnosis of Klinefelter's syndrome. Chromosomal analysis of the peripheral blood lymphocytes demonstrated the constitutional karyotype of 47, XXY. Using karyotype the presence of extra X chromosome was confirmed, supporting the cytogenetic finding. The 47, XXY syndrome is relatively uncommon and can be missed clinically because of its variable clinical presentations. Accurate diagnosis of this constitutional karyotype provides a valuable aid in the counselling and early management of the patients who undertake fertility evaluation. 相似文献

Treatment of male infertility 总被引:4,自引:0,他引:4
Male factor infertility is a general term that describes a situation in which the inability to conceive is associated with an alteration identified in the male partner. This dysfunction may be associated with low sperm concentration (oligozoospermia), poor sperm motility (asthenozoospermia) or abnormal sperm morphology (teratozoospermia); however, generally, a disturbance of all these variables, oligoasthenoteratozoospermia, is mostly frequent in male subfertility. For many andrological disorders, it is not possible to find a reasonable cause and various uncontrolled treatments have been applied to infertile men, often just on an empirical basis. More recently, after the explosive development of modern assisted reproduction techniques (ARTs), feasible with a single spermatozoon [intracytoplasmic sperm injection (ICSI)], the treatment of male infertility has received new meaning and andrologists are no longer expected to achieve a quantitative increase in sperm number but are instead asked to improve the fertility potential of the single sperm cell in order to achieve better results in both in vitro fertilization and ICSI. Additional prospective studies are needed to better understand the possible role of therapy in ART candidate patients. 相似文献

OBJECTIVES—To test the hypothesis that leatherwork is associated with male infertility mediated through the development of oligozoospermia. The basis of any association was postulated, at the outset, to be with exposure to the solvents used in leatherwork.
METHODS—All new referrals with infertility presenting in Leicestershire hospital clinics between November 1988 and September 1992 and Kettering District General Hospital from August 1990 were eligible to participate; 88.5% agreed to be interviewed. Exposure to leatherwork and work with solvents was defined by job title. Comparisons were made with fertile controls and in an analysis within men from infertile couples with oligozoospermia as the primary outcome. Effects on sperm motility and deformity were investigated secondarily. Analyses used logistic regression for binary outcomes and multilevel modelling for continuous outcomes.
RESULTS—1906 men were interviewed. Compared with the fertile controls the men from infertile couples were 1.10 times (95% confidence interval (95% CI) 0.46 to 2.63; p=0.99) more likely to be leatherworkers and 1.73 times (95% CI 1.26 to 2.38; p<0.001) more likely to work with solvents. Compared with other men, leatherworkers were 1.20 times (95% CI 0.43 to 3.33; p=0.73) more likely to present with oligozoospermia and 1.65 times (95% CI 0.37 to 7.30; p=0.51) more likely to present with teratozoospermia. Being a leatherworker was associated with only a 6% reduction in sperm concentration; motility and deformity were similarly unaffected by this exposure. Work with solvents did not statistically, nor clinically, increase the risk of oligozoospermia, teratozoospermia, or asthenozoospermia.
CONCLUSIONS—There was little evidence to support the hypothesis that leatherwork is associated with an increased risk of presenting with infertility or oligozoospermia. There was limited evidence that leatherwork is a risk factor for teratozoospermia. Workers with solvents were at an increased risk of presenting with infertility, although this was not mediated through effects on standard measures of semen quality; this finding merits further investigation.

日益严重的空气污染已对人们的生命健康构成巨大的危害。大量的流行病学研究表明,严重的空气污染对生殖系统有着多重负面影响。对男性而言,可导致睾丸体积减小和质量减轻,精子数量、浓度降低,运动力与形态学改变,并可引起精子染色体畸变、DNA断裂,最终表现为男性生殖功能的下降,导致不育。而对女性,空气污染与卵巢结构与功能受损、生殖细胞发育异常、排卵率下降以及雌激素分泌异常等显著相关。另外,长期暴露于空气污染的环境中,孕妇的流产率明显增高,且更易造成胎儿畸形的发生。综述多种主要空气污染物对男、女生殖器官(系统)、生殖细胞、生殖功能及胚胎发育影响的最新研究进展。 相似文献
