目的:通过评估ICSI治疗前的精子畸形率(SMR)和精子DNA碎片指数(DFI),探讨精子DFI和SMR对卵胞浆内单精子注射(ICSI)助孕结局的影响。方法:共入组79对因少弱精子症实施第一周期ICSI治疗的不孕夫妇,在进入治疗周期前36个月,评价精子浓度、前向运动精子百分率、SMR及DFI。主要观察SMR和DFI与ICSI结局参数的关系。结果:79例少弱精子症患者DFI正常51例,异常28例,异常组的DFI值明显升高(14.18%vs 41.47%);巧合的是,SMR正常组同样为51例,异常组28例,异常组的SMR值亦明显升高(87.88%vs98.46%)。按DFI正常(DFI≤25%)与异常(DFI>25%)分组,或按SMR正常(≤96%)与异常(>96%)分组,组间的双方年龄、女方BMI、获卵数、移植胚胎数等基本情况差异无统计学意义。DFI正常和异常组间,SMR正常和异常组间的受精卵子数、可移植胚胎数、早期流产率无显著差异;异常组生化妊娠率(43.5%vs 61.5%)和临床妊娠率(39.1%vs 56.4%)降低,但差异无统计学意义(P=0.19及0.10)。精子DFI与SMR呈显著正相关(r=0.231,P<0.05)。结论:精子DFI增高(>25%),与按严格标准检测的SMR增高(>96%)男性行ICSI治疗,生化妊娠率和临床妊娠率降低,但与正常者比较未发现有统计学差异,可能与样本量小有关,有必要深入研究。 相似文献

Our study objective was to assess the effect of various sperm DNA fragmentation levels on clinical intracytoplasmic sperm injection outcome. This retrospective study included 392 patients who underwent ICSI and performed sperm DNA fragmentation testing before the procedure. Based on sperm DNA fragmentation cut-off values, the patients were differentiated into 3 groups as <20%, 20%–30% and >30%. According to the female status, patients were differentiated into favourable group (n = 259) with female age <35 years and anti-Mullerian hormone level ≥7.1 pmol/L; and unfavourable group (n = 133) with female age ≥35 years and anti-Mullerian hormone level ≤7.1 pmol/L. The patient's medical records were reviewed, and patient's demographic, laboratory data including semen analysis, sperm DNA fragmentation determined by means of sperm chromatin dispersion, hormonal profile and data regarding intracytoplasmic sperm injection cycle were collected. This cohort reported that the clinical reproductive outcomes of intracytoplasmic sperm injection showed no statistical significance with increase sperm DNA fragmentation levels. In sperm DNA fragmentation above 30%, favourable females had significantly higher clinical pregnancy rate and live birth rate than unfavourable females, while fertilisation rate and miscarriage rate showed no significance between the subgroups. High sperm DNA fragmentation is linked to poor semen parameters. 相似文献

The purpose of this study was to compare the clinical outcome of testicular spermatozoon versus ejaculated spermatozoon in the treatment of infertile males with high sperm DNA damage, referred as sperm DNA fragmentation index (DFI), that attending intracytoplasmic sperm injection (ICSI) programme in terms of clinical pregnancy, births delivered as the primary and pregnancy loss and embryo fertilisation as the secondary outcome. A total of 102 males fulfilling the inclusion criteria were enrolled in the present study. Of the 102 males, 61 infertile males underwent testicular spermatozoon combined with ICSI while the remaining 41 males applied ejaculated spermatozoa in their first ICSI cycles, and the data of them were collected and analysed. In a 18‐month follow‐up, testicular spermatozoon achieved higher pregnancy rate and deliver rate than those in ejaculated sperm group (pregnancy rate, 36% vs. 14.6%, p = 0.017; deliver rate, 38.5% vs. 9.8%, p = 0.001). Nevertheless, there were no significant differences in the number of oocytes aspirated and number of embryos transferred between the two groups. Additionally, the fertilisation rate in the testicular sperm study cohort (70.4%) was also similar to that in the ejaculated sperm group (75.0%). Based on the current data, we conclude that testicular spermatozoon is the prior option in the treatment of infertile males with high sperm DFI in ICSI programme. More high‐quality studies with larger samples size are needed in the future due to the relative small size and the nonrandomized design of the present study. 相似文献

比较金黄地鼠和人卵浆内单精子注射技术受精率 总被引:3,自引:0,他引:3
卵浆内单精子注射技术(intracytoplasmicsperminjection,ICSI)1992年后已广泛应用于治疗严重的男性不孕患者,平均受精率可达65%~70%。但仍有大约1/3的卵在ICSI后未能受精。金黄地鼠ICSI试验(hamster ICSIasay)可能有助于在临床ICSI治疗前了解精子受精的潜力。为了证明金黄地鼠ICSI和人类ICSI受精率之间的相关性,探索金黄地鼠ICSI能否用为临床ICSI的预试验,本研究采用同一男性不孕患者的精子经显微注射技术在同一天分别注入人和金黄地鼠卵。16~18小时后在光镜下观察有无双原核形成(2 pronucleus,2PN)。人卵110个其受精率为582%(64/110)。金黄地鼠卵114个其受精率为165%(14/80)。经统计学处理,二者无相关性。金黄地鼠ICSI分为两组,A组:无选择地注射了已激活与未激活的卵63个;B组:注意选择未激活的卵共51个。虽经统计学处理无明显差异,但仍可看出B组的损伤率(197±166%)低于A组(359±5.7%)(P=008);而B组的受精率(183±10.9%)略高于A组(142±8.7%)(P=0? 相似文献

OBJECTIVE
To present the first UK data on sperm DNA fragmentation levels in subfertile men and fertile controls, the correlation with semen variables, and to assess the effect on the outcome of intracytoplasmic sperm injection (ICSI).PATIENTS, SUBJECTS AND METHODS
In all, 56 subfertile men undergoing ICSI (28 with positive and 28 with a negative outcome for paternity) and 10 control fertile semen donors were recruited. The sperm DNA fragmentation index (DFI) was assessed on raw pre‐preparation samples using the sperm chromatin structure assay. A mean of 5212 sperm were analysed per sample and DFI data are presented by fertility status, ICSI outcome and correlated with semen variables (assessed using World Health Organisation criteria).RESULTS
Total DFI was significantly higher in subfertile men than in fertile controls (mean and median of 22.8% and 17.0% vs 8.4% and 5.0%; P < 0.001), as was the proportion of both moderate DFI (16.4% and 13.0% vs 6.4% and 4.0%; P = 0.001) and high DFI (6.2% and 6.1 vs 2.0% and 1.0%; P = 0.01). This difference remained significant when the control men were compared only with the subfertile men with successful paternity. There was no significant difference in DFI in the subfertile men when analysed by ICSI outcome (mean and median of 24.5% and 17.0% vs 22.3% and 21.0% for successful and unsuccessful cycles, respectively; P = 0.94). There was a positive statistically significant correlation (r = 0.37; P = 0.02) between the DFI and sperm morphology.CONCLUSIONS
This study confirms a relationship between male subfertility and sperm DFI; we discuss the correct role for genetic testing of sperm in the evaluation of subfertile men. Although DNA fragmentation data might help to decide a suitable treatment, once it is decided to proceed with ICSI, DFI levels have no effect on the outcome. 相似文献17.
The aim of this study was to investigate the effect of varicocele on DNA fragmentation index (DFI), zinc concentration and seminal parameters in infertile patients. In this prospective study, 179 men with at least 1‐year history of infertility and varicocele were examined for semen quality at Hanoi Medical University Hospital (HMUH), Hanoi, Vietnam. In addition, an inverse correlation between zinc concentration and the degree of sperm DNA fragmentation in patients with clinical varicocele was found. The difference in mean values of sperm DNA fragmentation index in patients with various grades of varicoceles can be neglected, whereas most patients with varicocele of grades II and III had DFI >30%. Varicocele is associated with high levels of DNA damage in spermatozoa and reduced zinc levels that correlate with different grades of disease. Therefore, DNA fragmentation index and zinc concentration can be used as essential additional diagnostic test for patients with clinical varicocele. A study should be conducted to evaluate the benefits of zinc supplementation to improve seminal parameters in patients with varicocele. 相似文献
