目的:探讨血清抑制素B(INHB)在非梗阻性无精子症中的应用及对睾丸精子抽吸结局的预测作用。方法:用回顾性分析方法对52例非梗阻性无精子症(NOA)、12例梗阻性无精子症(OA)及20例正常生育男性,采用双抗夹心ELISA法测定各组血清中INHB水平;采用化学发光法测定各组血清中卵泡刺激素(FSH)、黄体生成素(LH)和睾酮(T)水平。结果:NOA组血清INHB水平明显低于正常生育男性组和OA组,其差异均有统计学意义(P<0.01);血清FSH和LH水平明显高于OA组和正常生育男性组(P<0.01)。NOA组行睾丸抽吸(TESE)获得精子的患者,其血清INHB水平明显高于未获得精子者,其差异有统计学意义(P<0.01);而NOA组行TESE未获得精子的患者,其血清FSH水平明显高于获得精子者,其差异有统计学意义(P<0.01)。比较两组血清中LH和T水平,其差异均无统计学意义(P>0.05)。结论:血清INHB水平可反映睾丸精子发生的情况,能准确预测TESE获取精子的结局。 相似文献

目的:探讨吸烟、精浆锌与不育男性患者精子形态的关系。方法:对115例男性不育患者的吸烟情况进行问卷调查,采用精子形态检测系统下人工修正方法分析共精子形态,以分光光度比色法测定精浆锌含量。结果:不育男性吸烟组精浆锌水平显著低于不吸烟组(P<0.05),且吸烟程度与精浆锌水平呈显著负相关性(r=-0.273,P<0.05);吸烟组正常形态精子百分率显著低于不吸烟组(P<0.05);吸烟精浆锌异常组正常形态精子百分率显著低于吸烟精浆锌正常组(P<0.05),且显著低于不吸烟精浆锌正常和异常组(P<0.01);不吸烟精浆锌异常组正常形态精子百分率与精浆锌正常组差异无统计学意义(P>0.05)。结论:吸烟能使精浆锌水平降低;吸烟对精子形态的影响可能通过降低精浆锌含量,增加氧化应激,使正常形态精子百分率下降。 相似文献

目的:探讨男性不育症患者血浆白细胞介素6(IL-6)与血清生殖激素水平及精子浓度的相关性及临床意义。方法:检测68例男性不育症患者精子浓度、血浆IL-6与血清睾酮(T)、黄体生成激素(LH)、卵泡刺激素(FSH)、催乳激素(PRL)水平,并与40例正常生育男性检测结果进行对照分析。结果:不育组血清T水平显著低于生育组(P<0.01),而血浆IL-6水平高于生育组(P<0.01)。不育组血浆IL-6水平与血清T水平呈负相关(P<0.05),而与血清FSH水平呈正相关(P<0.05)。不育患者中,精子浓度正常者较少精子症者血浆IL-6水平升高(P<0.01),T水平降低(P<0.01)。结论:血浆IL-6的水平与男性生殖密切相关,不仅对不育症的诊断、临床治疗及预后判断具有良好的参考价值,也可为不育症发病机制的研究提供新的思路。 相似文献

目的探讨少弱精子症患者生殖道感染与精子质量及精浆中性α-葡萄糖苷酶的相关性。方法分析2011年1月-2015年12月检测的精液分析结果和精浆生化资料。结果少弱精子症的确诊感染者较精浆弹性硬蛋白酶正常者的精液量、精子总数、精浆中性α-葡萄糖苷酶降低,差异有统计学意义(P0.05)。少弱精子症患者精浆中性α-葡萄糖苷酶测定值随精液量的减少而降低,差异均有统计学意义(P0.05)。非严重少弱精子症确诊感染组患者的血清FSH测定值高于正常组,差异有统计学意义(P0.05)。结论生殖道感染可引起少弱精子症患者精浆中性α-葡萄糖苷酶异常。生殖道感染可能是导致少弱精子症患者精液量减少,精子总数下降的重要病因之一。生殖道感染严重可能会影响睾丸生精功能。 相似文献

For the purpose to evaluate the significance of lipid peroxidative products on male infertility, the levels of malondialdehyde (MDA), which is one of the final products of lipid peroxidation in seminal plasma, were determined. Ninety-three male infertile patients were divided into obstructive azoospermic group (12 cases), non-obstructive azoospermic group (15 cases), oligozoospermic group (21 cases), asthenozoospermic group (19 cases), oligoasthenozoospermic group (16 cases) and oligoasthenoteratozoospermic group (10 cases). Eighteen fertile males were included in the control group. MDA concentrations of seminal plasma in the fertile and infertile men were detected by high-performance liquid chromatography (HPLC). The results showed that the concentration of MDA in seminal plasma differed significantly between the control group and all the infertile groups (P?<?0.01) except the obstructive azoospermic group, between the oligoasthenozoospermic group and the oligozoospermic and asthenozoospermic groups (P?<?0.01), and between the oligoasthenoteratozoospermic group and the oligozoospermic and asthenozoospermic groups (P?<?0.01). MDA concentration of seminal plasma in the oligoasthenoteratozoospermic group differed significantly from that in the oligoasthenozoospermic group (P?<?0.05). The results suggested that detection of MDA concentrations in seminal plasma by HPLC has an indicative value on the diagnosis of male infertility induced by overproduction of reactive oxygen species in male reproductive system. 相似文献

We explored the relationship between sperm chromatin integrity, hormone levels, seminal plasma total antioxidant capacity (TAC), and routine sperm parameters in men with male factor (MF, n?=?81) and non-male factor (NMF, n?=?52) infertility. Semen and blood were collected and examined from men undergoing evaluation for infertility in the Avicenna Infertility Clinic. We have examined each patient for serum hormones (LH, FSH, E2, DHEA), sperm chromatin damage, level of protamination and seminal plasma TAC. Levels of FSH, LH, sperm chromatin damage, and abnormal protamination were significantly higher in MF vs. NMF groups (p?0.001). Sperm chromatin damage was correlated with percentage of CMA(3)- positive sperm (r?=?0.64, p?0.001) and with sperm concentration (r?=?-0.36, p?0.001), motility (r?=?-0.21, p?0.05), and morphologically normal spermatozoa (r?=?-0.29, p?0.001). Linear regression showed sperm chromatin damage was related to percentage of CMA(3)- positive sperm (p?0.001) in ungrouped patients. It was related to both percentage of CMA(3)- positive sperm and serum DHEA in the MF group (p?0.001 and p?0.05, respectively). Sperm chromatin maturity assessed by CMA(3) test was inversely related to sperm chromatin damage assessed by the toludine blue assay. Male factor infertility associated with sperm chromatin damage may be related to sperm protamination and to serum DHEA. 相似文献

目的:探讨不育男性精浆的锌含量与精液质量的关系。方法:回顾性分析2011年8月~2012年1月在广西壮族自治区妇幼保健院生殖中心就诊的343例男性不育患者的相关资料,依据精浆锌含量分为正常A组(n=274例)和异常B组(n=69例),比较两组间精液参数的差异;同时根据精液黏稠度分为黏稠C组(n=54例)与非黏稠D组(n=289例),比较两组间精浆锌含量及其他精液参数的差异。结果:A组与B组患者年龄比较差异无统计学意义(P>0.05)。A组的精液量、每次射精精子总数、前向运动精子总数显著高于B组,而黏稠精液的比例明显低于B组,差异均有统计学意义(P<0.05)。其他精液各指标比较差异无统计学意义(P>0.05);C组与D组精液圆细胞浓度、精液量、精子浓度、精子总数比较差异无统计学意义(P>0.05);D组的前向运动精子百分率、前向运动精子总数、活动率、精浆锌明显高于C组,差异有统计学意义(P<0.05)。精浆锌含量与精液量、每次射精精子总数、前向运动精子总数显著正相关,与其他参数无显著相关性。结论:精浆锌含量直接影响精液量、精子总数、前向运动精子总数和精液黏稠度,精浆锌含量是男性生殖力的重要评估指标。 相似文献

This study was conducted to evaluate and compare the total antioxidant capacity among fertile and infertile men. Thirty infertile patients and 20 fertility-proven healthy donors with normal sperm analysis were included in the study. Total antioxidant capacity, zinc and fructose levels of seminal plasma, and various sperm parameters were compared among fertile controls and idiopathic infertility patients prospectively. The mean antioxidant capacity of fertile controls (2.02 - 0.16 mmol/L) was significantly higher than that of the infertile patients group (1.78 - 0.23 mmol/L) ( p <.01). Furthermore, asthenozoospermic and asthenoteratozoospermic groups had significantly lower mean antioxidant values (1.73 - 0.11 and 1.64 - 0.13, respectively) when compared to fertile control group ( p <.01). The mean fructose level was significantly lower in the fertile control group and mean zinc level was significantly lower in the entire infertile group. On the other hand, antioxidant capacity is positively correlated to sperm motility ( p =.001). Decreased antioxidant capacity was associated with impaired sperm function as a result of either increased ROS production or insufficient antioxidant capacity. 相似文献

Endocrine profile and seminal plasma composition in 45 patients with tuberculoid-type Hansen's disease are reported. There was marked reduction in sperm count and motility (p less than 0.01, p less than 0.01, respectively) with an increase in abnormal forms of spermatozoa (p less than 0.05). The levels of serum prolactin and oestradiol-17B were increased significantly (p less than 0.05, p less than 0.05, respectively) with a marked reduction in serum FSH, LH and testosterone (p less than 0.05, p less than 0.05, p less than 0.05, respectively). The possible significance of these findings may help further to understand male reproductive function in Hansen's disease. 相似文献

The association of leptin (LEP) -2548G/A and/or leptin receptor (LEPR) Gln223Arg polymorphisms with male infertility and plasma FSH, LH, and testosterone (T) levels was examined. The genotypes and allele frequency distributions of LEP -2548G/A and LEPR Gln223Arg polymorphisms were investigated in 150 fertile and 150 infertile men by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Also, plasma levels of FSH, LH, and T were measured using commercial ELISA kits. Frequencies of AA, AG and GG genotypes of LEP-2548G/A polymorphism were statistically different in fertile and infertile men (p=0.012). The AG genotype showed a protective effect which could decrease risk of male infertility about 3 fold (p = 0.004). We did not observe any differences in frequencies of LEPR Gln223Arg alleles and genotypes between groups (p > 0.05). Sperm counts from infertile men with the AG and GG genotypes of the LEP polymorphism were significantly higher than AA genotype (p<0.05). Moreover, infertile men who carried the RR genotype of LEPR showed a statistically higher percentage of sperm with progressive motility than individuals with other genotypes (p = 0.004). There was no correlation between different combinations of LEP and LEPR genotypes and LH, FSH, and T levels (p > 0.05). Our study suggests that the LEP -2548G/A polymorphism may play a role in male fertility and the AG genotype may have a protective effect through increasing sperm counts. The distribution of genotypes of LEP -2548G/A polymorphism are different in fertile and infertile males and may be a useful tool in evaluation of male infertility.
