Due to the biochemical complexity of seminal fluid, we attempt to study the possible correlation between fructose, which is secreted under the effect of androgen hormone, and autoimmunity, which might play a role in varicocele associated infertility, in reducing sperm motility. Seminal fructose, antisperm antibodies (ASAs) and blood steroids hormones (testosterone and progesterone) levels were measured in 66 infertile males with varicocele and 84 without varicocele referred for fertility treatment. Seminal analysis was performed with biochemical measurements of seminal fructose and mixed agglutination reaction (MAR) for ASA. Serum levels of progesterone and testosterone were estimated using a competitive chemoluminescent enzyme immunoassay. The mean values for serum testosterone were 380.74 ± 24.331, 365.9 ± 16.55, and 367.5 ± 21.8 ng/dl, progesterone 0.325 ± 0.243, 0.341 ± 0.022, and 0.357 ± 0.0306 ng/ml, and seminal plasma fructose 359.6 ± 26.75, 315.6 ± 13.08, and 332.08 ± 24.38 mg/dl in males with varicocele, without varicocele, and fertile males, respectively. A significant high level of testosterone was observed within varicocele group (P = .001). This result showed that testosterone may play a role as an infertility determinant in subjects with varicocele. ASA was detected in 18 (26.47%) of cases with varicocele, 20 (38.46%) without varicocele, and in 16 (32.0%) fertile men. Cases with ASAs associated with low sperm motility morphology. An inverse correlation between sperm-bound antibodies and viscosity has been shown (P = .017). ASA showed some significant inverse relations with ages, durations of infertility, and viscosity (P < .05). In addition, a significant correlation was observed between ASA positive seminal plasma and testosterone concentration among infertile cases (with or without varicocele) and fertile (P < .05). Our results suggest a relationship between testicular steroid hormone levels with autoimmunity and sperm antibodies which influence the motility of ejaculated spermatozoa among Jordanian infertile males.
由于精液的生化复杂性,我们试图研究在雄激素作用下分泌的果糖与自身免疫之间可能存在的相关性,自身免疫可能在精索静脉曲张相关性不育中发挥作用,影响精子活力。我们对66名因精索静脉曲张而不育的男性以及84名因生育问题前来治疗但无精索静脉曲张的男性进行了精液果糖、抗精子抗体(ASA)和血液甾体激素(睾酮和孕酮)水平的检测。通过精液果糖的生化测定和针对ASA的混合凝集反应(MAR)进行精液分析。使用竞争性化学发光酶免疫测定法估算血清孕酮和睾酮水平。精索静脉曲张男性、无精索静脉曲张男性和可育男性的血清睾酮平均值分别为380.74±24.331、365.9±16.55和367.5±21.8 ng/dl,孕酮分别为0.325±0.243、0.341±0.022和0.357±0.0306 ng/ml,精浆果糖分别为359.6±26.75、315.6±13.08和332.08±24.38 mg/dl。在精索静脉曲张组中观察到睾酮水平显著升高(P = 0.001)。这一结果表明,睾酮可能在精索静脉曲张患者的不育中起决定作用。在精索静脉曲张患者中有18例(26.47%)检测到ASA,无精索静脉曲张患者中有20例(38.46%)检测到ASA,可育男性中有16例(32.0%)检测到ASA。ASA与精子活力形态低下相关。已显示精子结合抗体与精液黏稠度呈负相关(P = 0.017)。ASA与年龄、不育持续时间和精液黏稠度呈显著负相关(P < 0.05)。此外,在不育患者(有或无精索静脉曲张)和可育男性中,ASA阳性的精浆与睾酮浓度之间存在显著相关性(P < 0.05)。我们的研究结果表明,约旦不育男性的睾丸甾体激素水平与自身免疫和精子抗体之间存在关联,这些因素会影响射出精子的活力。
