Beta-endorphin in serum and seminal plasma in infertile men

Aim:To access beta-endorphin levels in serum as well as seminal plasma in different infertile male groups.Methods:Beta-endorphin was estimated in the serum and seminal plasma by enzyme-linked immunosorbent assay(ELISA)method in 80 infertile men equally divided into four groups:non-obstructive azoospermia(NOA),obstructive azoosper-mia(OA),congenital bilateral absent vas deferens(CBVAD)and asthenozoospermia.The results were compared tothose of 20 normozoospermic proven fertile men.Results:There was a decrease in the mean levels of beta-endorphin in the seminal plasma of all successive infertile groups(mean±SD:NOA 51.30±27.37,OA 51.88±9.47,CBAVD 20.36±13.39,asthenozoospermia 49.26±12.49 pg/mL,respectively)compared to the normozoospermicfertile control(87.23±29.55 pg/mL).This relation was not present in mean serum level of beta-endorphin betweenfour infertile groups(51.09±14.71,49.76±12.4,33.96±7.2,69.1±16.57 pg/mL,respectively)and the fertilecontrol group(49.26±31.32 pg/mL).The CBVAD group showed the lowest seminal plasma mean level of beta-endorphin.Testicular contribution of seminal beta-endorphin was estimated to be approximately 40%.Seminal beta-endorphin showed significant correlation with the sperm concentration(r=0.699,P=0.0188)and nonsignificantcorrelation with its serum level(r=0.375,P=0.185)or with the sperm motility percentage(r=0.470,P=0.899).Conclusion:The estimation of beta-endorphin alone is not conclusive to evaluate male reproduction as there aremany other opiates acting at the hypothalamic pituitary gonadal axis.(Asian J Androl 2006 Nov;8:709-712)     

Effect of smoking on seminal plasma ascorbic acid in infertile and fertile males

This work aimed to assess the relationship of seminal ascorbic acid levels with smoking in infertile males. One hundred and seventy men were divided into four groups: nonobstructive azoospermia [NOA: smokers (n = 20), nonsmokers (n = 20)]; oligoasthenozoospermia [smokers (n = 30), nonsmokers (n = 20)]; asthenozoospermia [smokers (n = 20), nonsmokers (n = 20)] and normozoospermic fertile men [smokers (n = 20), nonsmokers (n = 20)]. The patients underwent medical history, clinical examination, conventional semen analysis and estimation of ascorbic acid in the seminal plasma calorimetrically. There was a significant decrease in the mean seminal plasma ascorbic acid levels in smokers versus nonsmokers in all groups (mean +/- SD; 6.03 +/- 2.18 versus 6.62 +/- 1.29, 7.81 +/- 1.98 versus 9.44 +/- 2.15, 8.09 +/- 1.98 versus 9.95 +/- 2.03, 11.32 +/- 2.15 versus 12.98 +/- 12.19 mg dl(-1) respectively). Fertile subjects, smokers or not, demonstrated significant higher seminal ascorbic acid levels than any infertile group. Seminal plasma ascorbic acid in smokers and nonsmokers was correlated significantly with sperm concentration (r = 0.59, 0.60, P < 0.001), sperm motility (r = 0.65, 0.55, P < 0.001) and negatively with sperm abnormal forms per cent (r = -0.53, -0.50, P < 0.001). Nonsignificant correlations were elicited with semen volume (r = 0.2, 0.09) or liquefaction time (r = 0.03, 0.06). It is concluded that seminal plasma ascorbic acid decreased significantly in smokers and infertile men versus nonsmokers and fertile men, and is significantly correlated with the main sperm parameters: count, motility and normal morphology. Also, cigarette smoking is associated with reduced semen main parameters that could worsen the male fertilizing potential, especially in borderline cases.     

Seminal plasma anti-Müllerian hormone level correlates with semen parameters but does not predict success of testicular sperm extraction (TESE)

AIM: To assess seminal plasma anti-Müllerian hormone (AMH) level relationships in fertile and infertile males. METHODS: Eighty-four male cases were studied and divided into four groups: fertile normozoospermia (n = 16), oligoasthenoteratozoospermia (n = 15), obstructive azoospermia (OA) (n = 13) and non-obstructive azoospermia (NOA) (n = 40). Conventional semen analysis was done for all cases. Testicular biopsy was done with histopathology and fresh tissue examination for testicular sperm extraction (TESE) in NOA cases. NOA group was subdivided according to TESE results into unsuccessful TESE (n = 19) and successful TESE (n = 21). Seminal plasma AMH was estimated by enzyme linked immunosorbent assay (ELISA) and serum follicular stimulating hormone (FSH) was estimated in NOA cases only by radioimmunoassay (RIA). RESULTS: Mean seminal AMH was significantly higher in fertile group than in oligoasthenoteratozoospermia with significance (41.5 +/- 10.9 pmol/L vs. 30.5 +/- 10.3 pmol/L, P < 0.05). Seminal AMH was not detected in any OA patients. Seminal AMH was correlated positively with testicular volume (r = 0.329, P = 0.005), sperm count (r = 0.483, P = 0.007), sperm motility percent (r = 0.419, P = 0.021) and negatively with sperm abnormal forms percent (r = -0.413, P = 0.023). Nonsignificant correlation was evident with age (r = -0.155, P = 0.414) and plasma FSH (r = -0.014, P = 0.943). In NOA cases, seminal AMH was detectable in 23/40 cases, 14 of them were successful TESE (57.5%) and was undetectable in 17/40 cases, 10 of them were unsuccessful TESE (58.2%). CONCLUSION: Seminal plasma AMH is an absolute testicular marker being absent in all OA cases. However, seminal AMH has a poor predictability for successful testicular sperm retrieval in NOA cases.

不育男性精浆总抗氧化能力与精子运动功能的关系

目的:研究不育男性精浆总抗氧化能力(TAC)与精子运动能力和方式之间的关系,探讨精浆TAC水平在男性生育中的临床意义。方法:113例精子密度正常的不育男性,28例正常生育男性作为对照组。精液于37℃液化后采用计算机辅助精液分析(CASA)系统进行精液常规分析,采用比色法进行精浆TAC分析。结果:正常生育组精浆TAC为(19.82±6.33)U,不育男性精子密度正常组精浆TAC为(14.37±8.45)U,不育男性精子密度正常组与正常生育组比较存在显著性差异(P<0.01)。精浆TAC与a级精子百分率(r=0.208,P<0.05)和(a+b)级精子百分率(r=0.231,P<0.05)呈显著正相关,精浆TAC与精子运动参数中的前向性(r=0.200,P<0.05)、直线性(r=0.208,P<0.05)、曲线速度(r=0.189,P<0.05)、直线速度(r=0.210,P<0.05)、平均移动速度(r=0.215,P<0.05)及鞭打频率(r=-0.248,P<0.01)之间有显著的相关性,其中前向性、直线性、直线速度、曲线速度、平均移动速度与TAC呈正相关(P<0.05),而鞭打频率与TAC呈负相关(P<0.01)。精浆TAC与摆动性、侧摆幅度、平均移动角度之间无显著相关。结论:精浆中TAC水平与精子运动能力和运动方式密切相关,适宜的精浆TAC为精子运动提供了良好的外部环境,精浆中过低的TAC水平与精子运动能力下降和运动方式改变有关,可能是引起男性不育的病因之一。精浆中TAC分析可为探讨男性不育的发病机制以及临床用药提供依据。     

精浆游离L-肉毒碱水平及其与精子密度、活动率及活力的相关性研究

目的:研究正常生育及不育男性精浆中游离L-肉毒碱水平差异及其与精子密度、活动率(a+b+c级精子百分率)及活力(a+b级精子百分率)之间的相关性,探讨精浆中游离L-肉毒碱水平对男性生育力的影响及其在不育症检查和治疗中的作用。方法:分别采用高效液相色谱法和计算机辅助精液分析系统,测定了230例不育症患者(精子密度正常117例,少精子症81例,无精子症32例)和30例正常生育男性精浆中游离L-肉毒碱水平及精子密度、活动率、活力等参数。根据检查结果对不育症患者分组后,以SPSS12.0软件包进行统计学分析,比较各组间游离L-肉毒碱水平的差异以及游离L-肉毒碱水平与精子密度、活动率、活力之间的相关性。结果:正常生育组精浆游离L-肉毒碱水平明显高于不育组(P<0.01)。精液中精子密度越低、活力越弱,这种差异性越显著。相关性分析结果显示,精浆游离L-肉毒碱水平与精子密度呈显著正相关关系(r=0.521,P<0.01),与精子活动率和活力之间也具有正相关关系(r=0.319,P<0.01;r=0.251,P<0.01)。结论:精浆L-肉毒碱水平与精子密度、活动率和活力之间密切相关,其含量测定作为一项有用的生化指标,可为男性不育症检查及临床诊治和进行有关男性生殖功能机制研究提供参考。     

Comparison of zinc concentrations in blood and seminal plasma and the various sperm parameters between fertile and infertile men

The aim of the study was to examine the relationships between concentrations of zinc in blood and seminal plasma and sperm quality among infertile and fertile men. One hundred seven male (infertile group) partners of couples who were undergoing investigation for infertility with no known cause for the infertility and 103 men (fertile group) whose wives were pregnant at the time of the study were recruited. The subjects' blood and seminal plasma concentration of zinc were determined by atomic absorption spectroscopy. Except for semen volume, all the other semen parameters for the infertile men were significantly lower than those for the fertile group. The geometric means of the seminal plasma zinc concentration were significantly lower in the infertile group compared with those in the fertile group; 183.6 mg/L (range, 63-499) versus 274.6 mg/L (range, 55-420). There were no significant differences in the geometric means of the blood zinc concentration between the 2 groups. Seminal plasma zinc concentration was significantly correlated with sperm density (r = 0.341, P < .0001), motility (r = 0.253, P < .0001), and viability (r = 0.286, P < .0001). On the basis of the findings of this study and those of other reports, zinc may contribute to fertility through its positive effect on spermatogenesis.     

Seminal fibronectin in fertile and infertile males

This study aimed to assess seminal plasma fibronectin in fertile and infertile males. Ninety infertile males were investigated; asthenozoospermia (n = 27), asthenoteratozoospermia (n = 30), oligoasthenoteratozoospermia (n = 33) compared with 20 healthy fertile controls. They were subjected to semen analysis, seminal plasma fibronectin estimation by radial immune diffusion, serum testosterone (T) and follicle stimulating hormone (FSH) estimation by ELISA. There was significant increase of seminal plasma fibronectin among different infertile groups compared with the controls. Significant negative correlation was elicited between seminal fibronectin and sperm count, sperm motility grades A, B, A + B, sperm velocity, linear velocity, linearity index, sperm normal forms and serum T. Seminal fibronectin showed significant positive correlation with grade D sperm motility and serum FSH. ROC curve analysis discriminating controls and other infertile groups demonstrated criteria value of < 674 mg l(-1) (sensitivity 100% and specificity 96.4%). It is concluded that increased seminal fibronectin is associated with decreased sperm count and sperm motility.     

Heme oxygenase enzyme activity in human seminal plasma of fertile and infertile males

This work aimed to assess heme oxygenase (HO) enzyme activity relationship with different human semen parameters. One hundred and twenty men were divided according to their sperm count and clinical examination into: obstructive azoospermia (n = 20), nonobstructive azoospermia (NOA) (n = 25), oligozoospermia (n = 35) and normozoospermia (n = 40). Semen analysis, western blot for HO-1 and HO-2, and estimation of seminal plasma HO enzyme activity chemically in the form of bilirubin concentration were carried out. Seminal plasma HO enzyme activity was very low in OA specimens, low in NOA, moderate in oligozoospermia while higher in normozoospermia (mean +/- SD; 6.26 +/- 2.2, 81.4 +/- 35.5, 283.8 +/- 90.1, 657.4 +/- 227.6 pmol ml(-1) min(-1)) with significant differences. Western blot analysis demonstrated HO-2 expression in all studied groups whereas HO-1 was highly expressed in fertile normozoospermic group compared with other groups. There was positive correlation between seminal plasma HO enzyme activity and sperm concentration, sperm motility percentage, motile spermatozoa ml(-1) and sperm normal morphology per cent. It is concluded that HO enzyme activity in the human seminal plasma is related to spermatogenesis and sperm-motility processes.     

alpha-1,4-Glucosidase activity in infertile oligoasthenozoospermic men with and without varicocele

This work aimed to assess seminal alpha-1,4-glucosidase activity in infertile oligoasthenozoospermic men associated with and without scrotal varicocele. Eighty men were investigated. They were divided into three groups: group 1 (n = 20), fertile normozoospermic men; group 2 (n = 30), oligoasthenozoospermia with varicocele; and group 3 (n = 30), oligoasthenozoospermia without varicocele. The patients underwent medical history, clinical examination, conventional semen analysis and estimation of seminal plasma alpha-1,4-glucosidase activity by double-beam spectrophotometer method and serum testosterone by radioimmunoassay method. There was a significant decrease in the mean seminal alpha-1,4-glucosidase activity levels in infertile men versus controls (mean +/- SD; 7.66 +/- 0.433, 2.088 +/- 0.565, 5.384 +/- 0.85 mU ml(-1) respectively). Mean serum testosterone levels demonstrated nonsignificant differences between studied groups. Seminal alpha-1,4-glucosidase activity levels demonstrated significant correlation with sperm count, sperm motility percentage and serum testosterone in oligoasthenozoospermia with varicocele group and demonstrated nonsignificant correlation in other groups. It is concluded that varicocele-induced hypoxia is the adverse effect that causes both oligoasthenozoospermia and decreased seminal alpha-1,4-glucosidase levels.     

Melatonin hormone profile in infertile males

Melatonin is a hormone produced by the pineal gland. There is much controversy about its relationship to the male reproductive process. In this study, seminal plasma as well as the serum melatonin levels were studied in different infertile male groups and were correlated with their semen parameters and hormonal levels. One hundred twenty male cases subdivided into six equal groups were consecutively included; fertile normozoospermic men, oligoasthenozoospermia (OA), OA with leucocytospermia, OA with varicocele, non-obstructive azoospermia (NOA) with high serum follicle stimulating hormone (FSH) and NOA with normal FSH. Semen analysis, estimation of melatonin, FSH, testosterone (T) and prolactin (PRL) hormone was carried out. Mean level of serum melatonin was higher than its corresponding seminal concentrations in all investigated groups with a positive correlation between their levels (r = 0.532, p = 0.01). Serum and seminal plasma melatonin levels in all infertile groups were reduced significantly compared with their levels in the fertile group. The lowest concentrations were in OA with leucocytospermia group. Melatonin in both serum and semen demonstrated significant correlation with sperm motility (r = 607, 0.623 respectively, p = 0.01). Serum melatonin correlated positively with serum PRL (r = 0.611, p = 0.01). It may be concluded that melatonin may be involved in the modulation of reproductive neuroendocrine axis in male infertility. Also, low levels of melatonin in semen were observed in infertile groups having reduced sperm motility, leucocytospermia, varicocele and NOA.     

精索静脉曲张不育患者精浆颗粒溶素与精液质量的相关性分析

目的探讨颗粒溶素在精索静脉曲张(VC)患者精液的表达水平及临床意义。方法选择2016年9月至2017年7月在本院就诊的80例男性不育患者作为观察组,其中45例为原发性VC(VC不育组),35例患者不合并VC(非VC不育组)。同时,本研究选取30例健康男性为可育对照组。检测所有入组精液精子密度、精子活动率、精子正常形态比例以及颗粒溶素的表达水平。结果VC不育患者精浆颗粒溶素的表达水平均显著高于可育对照组;此外,与非VC不育患者相比较,VC不育患者精浆颗粒溶素水平更高;精浆颗粒溶素的表达与精子浓度(r=-0.364,P<0.001)、精子活力(r=-0.397,P<0.001)和精子正常形态(r=-0.441,P<0.001)均呈负相关。结论不育合并VC患者精浆颗粒溶素表达水平显著高于正常健康人群,且其表达水平与VC等级密切相关。     

正常成年男性精浆同型半胱氨酸浓度及其与精液参数关联性研究

目的探讨正常成年男性精浆同型半胱氨酸(Hcy)的正常值参考范围;探讨精浆、血清Hcy浓度与精液参数的关联性以及精浆与血清Hcy浓度的关联性。方法从精子库捐精者中招募了31例健康志愿者,收集其精液及血清,检测其精液常规,采用酶联免疫吸附试验(ELISA)测定血清与精浆中的Hcy的浓度并计算精浆Hcy总含量;采用统计学软件SPSS 12.0分析精浆Hcy正常参考值范围,分析精浆、血清Hcy浓度,精浆Hcy总含量与精液参数的关联性以及精浆与血清Hcy的关联性。结果精浆Hcy浓度与精子活力呈负相关(r=-0.439,P=0.014),与其他精液参数无相关性;精浆与血清Hcy浓度之间也无相关性。结论健康青年男性精浆Hcy浓度的参考值范围:6.02~21.96μmol/L(95%CI);精浆Hcy浓度与精子活力呈负相关。     

Soluble Fas and interleukin-6 and interleukin-8 levels in seminal plasma of infertile men

The seminal plasma levels of soluble Fas (sFas) and interleukins IL-6 and IL-8 were measured and their relationship with semen qualities was examined. The seminal plasma sFas level in fertile males was significantly higher than that in the infertile group. On the other hand, seminal plasma level of IL-6 was significantly lower in fertile males than in the infertile group. In the infertile group, patients with oligozoospermia had a lower seminal plasma sFas and a higher IL-6 level than those with normal sperm concentration. There was an inverse correlation between IL-6 and sperm concentration in infertile patients. Seminal plasma IL-8 was not correlated with sperm parameters. It would appear that certain kinds of cytokine in the seminal plasma might play an important role in improving semen quality.     

Zinc in human semen

Seminal zinc was measured in normospermic and infertile patients by a new colorimetric method. Analysis of semen from 5 patients with bilateral agenesis of the vas deferens showed high levels of zinc (mean value 1411.2 micrograms/ml). Lower levels were found in 6 patients with monolateral congenital or acquired obstruction (695.2 micrograms/ml). The seminal zinc level in 6 patients who had had a vasectomy or who had an epididymal blockage (125.7 micrograms/ml) was approximately the same as in 41 controls (134.6 +/- 42 +/- SD). Zinc levels were reduced in hypogonadal patients. These data suggest that zinc is secreted mainly by the prostate, while vesicular, epididymal and testicular secretions are devoid of zinc. Evaluation of this metal therefore permits the diagnosis of patency of the seminal pathways, but does not permit identification of prostatitis. No correlation was found between sperm count or motility and the seminal zinc level, nor between the latter and varicocele.

Total anti-oxidant status: a biochemical predictor of human male fertility

The objective of the study was to assess whether seminal plasma total antioxidant status (TAS) can be used as a biochemical predictor of male fertility and its variation in different categories of infertile male subjects in our population. The study population consisted of 28 fertile and 127 infertile [teratozoospermic (30), asthenoteratozoospermic (30), azoospermic (21), oligoastheno-teratozoospermic (20), polyzoospermic (15) and oligozoospermic (11)] male subjects. Seminal plasma was separated by centrifugation and stored at minus 80 degree Celsius. Semen was analysed using computer-assisted semen analysis according to WHO criteria. Seminal plasma TAS was estimated by colorimetric method using Randox total antioxidant status kit. TAS of fertile male subjects was significantly (P < 0.001) higher than that of infertile patients. In whole studied population, seminal plasma TAS showed a significant positive correlation with sperm concentration (P < 0.001), sperm motility (P < 0.0001), and spermatozoa with normal morphology (P < 0.0001). In conclusion, this study suggests that TAS of seminal plasma is one of the important factors contributing to male infertility, and it can be used as a biochemical predictor for male fertility.
