  • 文章类型: Journal Article
    大约50%的不孕症病例归因于男性因素。长期以来,针灸一直被用作补充疗法,以增强男性不育的治疗效果。本研究旨在评估电针(EA)治疗对男性不育患者精子活力和TMSC的影响。
    这项随机临床试验将30名男性不育症患者分为两组。在生育诊所Sekar诊断为不孕症的男性中使用了连续抽样,Moewardi综合医院医生,苏拉卡塔.两组在干预前后都进行了精子活力和TMSC的评估。第一组接受辅酶Q,第二组接受辅酶Q+EA。
    QozymeQ+EA组在治疗前的运动水平没有显著差异,平均活动力为41.40%±13.33,TMSC水平为33.59×106±27.91。后处理,QozymeQEA组的运动性显着提高了56.40%±11.78,TMSC水平提高了78.63×106±58.38。相反,QozymeQ预处理组的平均运动性为48.07%±15.77,TMSC水平为30.20×106±34.82。辅酶Q处理后,运动能力显着下降42.80%±18.03,TMSC水平下降28.22×106±15.16。
    与单独的辅酶Q相比,辅酶Q+EA组合对精子运动性和TMSC水平具有更显著的影响。这些发现强调了辅酶Q+EA和辅酶Q对精子活力和TMSC水平的不同影响。提示对男性生殖健康的潜在治疗意义。未来的研究需要更大的样本量来验证和扩展这些结果。
    UNASSIGNED: Approximately 50% of infertility cases are attributed to male factors. Acupuncture has long been employed as a complementary therapy to enhance male infertility treatment outcomes. This study aimed to assess the impact of electroacupuncture (EA) therapy on sperm motility and TMSC in male infertility patients.
    UNASSIGNED: This randomized clinical trial involved 30 male infertility patients divided into 2 groups. Consecutive sampling was utilized among men diagnosed with infertility at the Fertility Clinic Sekar, Dr. Moewardi General Hospital, Surakarta. Both groups underwent assessments of sperm motility and TMSC before and after the intervention. The first group received Coenzyme Q, while the second group received Coenzyme Q + EA.
    UNASSIGNED: The Qoenzyme Q + EA group exhibited no significant difference in motility levels before treatment, with an average motility of 41.40% ± 13.33 and a TMSC level of 33.59 × 106 ± 27.91. Post-treatment, motility remarkably increased by 56.40% ± 11.78, and the TMSC level rose by 78.63 × 106 ± 58.38 in the Qoenzyme Q + EA group. Conversely, the Qoenzyme Q pre-treatment group had an average motility of 48.07% ± 15.77 and a TMSC level of 30.20 × 106 ± 34.82. After Coenzyme Q treatment, a significant decrease in motility by 42.80% ± 18.03 and TMSC level by 28.22 × 106 ± 15.16 was observed.
    UNASSIGNED: Combining Coenzyme Q + EA had a more significant impact on sperm motility and TMSC levels than Coenzyme Q alone. These findings underscore the differential effects of Coenzyme Q + EA and Coenzyme Q on sperm motility and TMSC levels, suggesting potential therapeutic implications for male reproductive health. Future studies with larger sample sizes are warranted to validate and expand upon these results.

    为了表征卵泡刺激素(FSH)在有生育能力和低生育能力的非无精子症男性中的分布,并确定各种FSH阈值预测生育状况的能力。
    我们对1389名非无精子症男性进行了一项回顾性队列研究。包括至少2次精液分析(SA)和1次FSH水平的男性。根据活动精子总数(TMSC),将男性分为可育和低可育组。FSH在多变量模型中进行评估,和不孕的阳性预测值(PPV)用于评估各种FSH阈值的临床效用.
    一千五千(80%)的男性被归类为可育,274(20%)的男性被归类为低可育。年龄,精索静脉曲张的存在,两组间睾酮水平无统计学差异。在可育和不可育男性中,FSH中位数为4.0vs6.0(P<.001)。在预测生育状态(PPV0.49-0.59)时,从2.9到9.3的多个FSH阈值相似。只有高于第95百分位数(12.1)的FSH阈值具有大于0.7的PPV。在FSH为20.8(第99百分位数)时观察到最高的PPV(0.84)。
    虽然在有生育能力和低生育能力的非无精子症男性中FSH水平存在显著差异,对于TMSC确定的生育状态的预测,在2.2至9.3之间的多个FSH截止值表现不佳.直到第95百分位FSH值,才达到临床上有用的低生育可预测性水平,表明FSH不应用作生育状态的独立测试。尽管如此,FSH测试在临床上仍然有用,并且在极端值或不一致的FSH和SA结果的设置中可能是最有用的信息。
    UNASSIGNED: Our goal was to characterize the distribution of follicle stimulating hormone (FSH) in fertile and subfertile nonazoospermic men, and to determine the ability of various FSH thresholds to predict fertility status.
    UNASSIGNED: We performed a retrospective cohort study of 1389 nonazoospermic men who presented for fertility evaluation. Men with at least 2 semen analyses and 1 FSH level were included. Men were dichotomized into fertile and subfertile groups based on total motile sperm count. FSH was evaluated within a multivariable model, and positive predictive values (PPVs) for subfertility were used to assess the clinical utility of various FSH thresholds.
    UNASSIGNED: One thousand fifteen (80%) men were classified as fertile and 274 (20%) as subfertile. Age, presence of varicocele, and testosterone levels were not statistically different between the groups. Median FSH was 4.0 vs 6.0 (P < .001) among fertile vs subfertile men. Multiple FSH thresholds ranging from 2.9 to 9.3 performed similarly in predicting fertility status (PPV 0.49-0.59). Only FSH thresholds above the 95th percentile (12.1) had PPVs greater than 0.7. The highest PPV (0.84) was seen at an FSH of 20.8 (99th percentile).
    UNASSIGNED: While there were significant differences in FSH levels among fertile and subfertile nonazoospermic men, multiple FSH cutoffs between 2.2 and 9.3 performed poorly for prediction of fertility status as determined by total motile sperm count. It was not until the 95th percentile FSH value that a clinically useful level of predictability for subfertility was reached, indicating that FSH should not be used as a standalone test of fertility status. Nonetheless, FSH testing remains clinically useful and may be most informative in the setting of extreme values or discordant FSH and semen analysis results.

    在宫腔内授精(IUI)时,女性通常会担心解冻的供体样品中精子的绝对量和质量。这项研究的目的是确定从商业精子库获得的供体精子的总活动精子数(TMSC)如何影响IUI后的妊娠率。
    我们进行了一项回顾性队列研究,包括2011年1月至2018年3月在单一学术生育中心接受IUI的单身女性和同性关系女性。我们的主要结果是每个IUI周期的怀孕率,由洗涤后的TMSC分层。根据TMSC分析数据并包括三个不同的组:TMSC小于5百万的样品;5-1千万的TMSC;和大于1千万的TMSC。妊娠由大于5mIU/mL的血清β-人绒毛膜促性腺激素(β-HCG)定义。进行卡方分析和相关系数。
    总的来说,在研究期间进行了9341个IUI。其中,使用市售供体精子对单身女性和同性关系的女性进行了1080(11.56%)。我们发现,基于TMSC的每次授精的妊娠率没有差异。TMSC少于500万的组每个周期的妊娠率为15/114(13.3%);TMSC为5-10万的34/351(9.5%);TMSC大于1000万的样本为61/609(10.0%)(p=0.52)。我们发现供体精子TMSC与IUI后妊娠之间的相关性不明显(r=-0.072)(p=0.46)。此外,IUI后16天得出的令人放心的β-HCG水平(>100IU/L)与TMSC无关(r=0.0071,p=0.94).
    IUI后的妊娠率不受市售供体精子的TMSC的影响。当发现新鲜解冻的供体精子具有较低的TMSC时,该结果可用于使患者放心。来自商业银行的冷冻精子样本通常仅代表满足银行年龄标准的捐赠者产生的射精的一部分,健康和精子质量。因此,冷冻导致的精子死亡并不会导致供体精子的不良结局。
    UNASSIGNED: Women are often concerned about the absolute quantity and quality of sperm in a thawed donor sample at the time of intrauterine insemination (IUI). The aim of this study was to determine how the total motile sperm count (TMSC) of donor sperm obtained from commercial sperm banks affects the pregnancy rate after IUI.
    UNASSIGNED: We performed a retrospective cohort study including single women and women in same-sex relationships undergoing IUI at a single academic fertility center between January 2011 and March 2018. Our primary outcome was pregnancy rates per IUI cycle, stratified by post-washed TMSC. The data was analyzed according to TMSC and included three different groups: samples with a TMSC less than 5 million; TMSC of 5-10 million; and a TMSC greater than 10 million. Pregnancies were defined by a serum Beta-human chorionic gonadotropin (Beta-HCG) of greater than 5 mIU/mL. Chi-squared analyses and correlation coefficients were performed.
    UNASSIGNED: Overall, 9341 IUIs were conducted during the study period. Of these, 1080 (11.56%) were performed for single women and women in a same-sex relationship using commercially available donor sperm. We found that there were no differences in the pregnancy rates per insemination based on TMSC. The pregnancy rates per cycle were 15/114 (13.3%) for the group with a TMSC of less than 5 million; 34/351(9.5%) with a TMSC of 5-10 million; and 61/609 (10.0%) for samples with a TMSC greater than 10 million (p = 0.52). We found an insignificant correlation (r = -0.072) between donor sperm TMSC and pregnancy after IUI (p = 0.46). Furthermore, a reassuring beta-HCG level (>100IU/L) drawn 16 days after IUI was unrelated to TMSC (r = 0.0071, p = 0.94).
    UNASSIGNED: The pregnancy rate following IUI is unaffected by the TMSC of commercially available donor sperm. This result is useful in reassuring patients when freshly thawed donor sperm is found to have a lower TMSC. Frozen sperm samples from commercial banks typically represent just a portion of an ejaculate produced by a donor who meets the banks\' standards for age, health and sperm quality. As such, exaggerated sperm death caused by freezing does not result in worse outcomes with donor sperm.

    UNASSIGNED:这项研究评估了患有严重少精子症(SO)的不育男性进行显微外科静脉曲张切除术是否导致精液参数改善或自然妊娠(SP)率增加,并进行了比较宫腔内人工授精(IUI)的成本效益分析。体外受精(IVF),和精索静脉曲张切除术.
    UNASSIGNED:本研究纳入了25例SO患者,他们在2019年9月至2022年5月期间接受了显微外科精索静脉曲张切除术,导致所有病例术后发生SP。男性无精子症,异常核型,或Y染色体微缺失被排除在研究之外。血清促黄体,刺激卵泡,术前测量睾酮激素。术后每3个月分析一次精液。每次就诊时记录SP的发生率。辅助生殖技术的成本效益是根据报告的成本进行计算的。使用单变量和多变量分析评估了一些参数作为显微外科精索静脉曲张切除术反应的潜在预测因子。
    UNASSIGNED:经过7个月的平均术后观察期,招募了25对显微外科精索静脉曲张切除术后的SP夫妇。平均精子浓度从3百万/mL(四分位间距[IQR]:2-5百万/mL)增加到12百万/mL(IQR:5-17百万/mL;p<0.05),平均精子活力从4%(IQR:3%-6%)提高到7.6%(p<0.05)。活动精子总数(TMSC)从术前的0.34万(IQR:0.16-0.83万)增加到308万(IQR:1.02-5.83万)。比较IVF和精索静脉曲张切除术的成本效益分析表明,精索静脉曲张切除术可能是术前TMSC非常低的不育男性的更好的一线选择。然而,需要进一步的研究来证实这一结果。
    UNASSIGNED:精索卵巢切除术应作为男性SO患者的治疗选择进行讨论,可以提高精子质量和生育能力,导致SP。
    UNASSIGNED: This study evaluated whether microsurgical varico-celectomy performed in infertile men with severe oligozoospermia (SO) resulted in improved semen parameters or increased rates of spontaneous pregnancy (SP) and performed a cost-effectiveness analysis comparing intrauterine insemination (IUI), in vitro fertilization (IVF), and varicocelectomy.
    UNASSIGNED: This study included 25 patients with SO who underwent microsurgical varicocelectomy between September 2019 and May 2022, which resulted in post-surgical SP in all cases. Men with azoospermia, abnormal karyotype, or Y-chromosome microdeletion were excluded from the study. Serum luteinizing, follicle-stimulating, and testosterone hormones were measured preoperatively. Semen was analyzed every 3 months postoperation. The incidence of SP was recorded at each visit. Cost-effectiveness for assisted reproductive technologies was calculated based on reported costs. Several parameters were evaluated as potential predictors of the response to microsurgical varicocelectomy using univariate and multivariate analyses.
    UNASSIGNED: After a mean postoperative observation period of 7 months, 25 couples with SP after microsurgical varicocelectomy were recruited. The mean sperm concentration increased from 3 million/mL (interquartile range [IQR]: 2-5 million/mL) to 12 million/mL (IQR: 5-17 million/mL; p<0.05), and mean sperm motility improved from 4% (IQR: 3%-6%) to 7.6% (p<0.05). Total motile sperm count (TMSC) increased to 3.08 million (IQR: 1.02-5.83 million) from a preoperative value of 0.34 million (IQR: 0.16-0.83 million). A cost-effectiveness analysis comparing IVF with varicocelectomy indicates that varicocelectomy may represent a better first-line option for infertile men with very low preoperative TMSC. However, further research remains necessary to confirm this result.
    UNASSIGNED: Varicocelectomy should be discussed as a treatment option for men with SO and may improve sperm quality and fertility potential, resulting in SP.

    宫腔内人工授精(IUI)是治疗不育夫妇的常用方法。有证据表明,在活动精子总数(TMSC)少于1000万的情况下,怀孕率下降,然而,在不育人群中推荐IUI的精液参数仍有待达成共识。这项研究的目的是确定精液分析中TMSC的最小阈值以提供IUI周期。这是一个为期四年的私人执业不孕不育中心所有IUI周期的回顾性队列研究。我们感兴趣的主要结果是每个周期后临床妊娠的存在。共有999名妇女接受了2,169个IUI周期。总体临床妊娠率为每周期19.8%。在第一次IUI期间,每个女人都接受了,临床妊娠随着TMSC≤1M的TMSC(OR0.44)增加至TMSC6-10M的TMSC(OR0.99)增加,与TMSC>10M相比,在TMSC在6到10M之间的所有IUI中,妊娠结局改善与形态学>4%(OR0.84),与形态<4%(OR0.25)相比,相对于TMSC>10M。使用接收器工作特性曲线,我们没有确定提供IUI的TMSC门槛,尽管TMSC和IUI成功之间存在正相关。
    Intrauterine insemination (IUI) is a frequently used method to treat couples with infertility. There is evidence of decreased pregnancy rates with a total motile sperm count (TMSC) of less than 10 million, yet there remains to be a consensus on semen parameters for which to recommend IUI in the infertile population. The aim of this study was to determine a minimum threshold of TMSC on semen analysis to offer IUI cycles. This is a retrospective cohort study of all IUI cycles at a private practice infertility centre over four years. Our primary outcome of interest was the presence of clinical pregnancy after each cycle. A total of 999 women underwent 2,169 IUI cycles. The overall clinical pregnancy rate was 19.8% per cycle. During the first IUI each woman underwent, there was an increase in clinical pregnancy with increasing TMSC (OR 0.44) for TMSC ≤1 M to (OR 0.99) for TMSC 6-10 M, compared to TMSC >10 M. Among all IUI with a TMSC between 6 and 10 M, pregnancy outcomes improved with morphology >4% (OR 0.84), compared to morphology <4% (OR 0.25), relative to TMSC >10 M. Using receiver operating characteristic curves, we did not identify a TMSC threshold to offer IUI, although there was a positive correlation between TMSC and IUI success.

    目的:这项研究的目的是阐明基于孕妇年龄,哪些洗前总运动量与改善的临床妊娠率(CPR)和活产率(LBR)相关,AMH水平,刺激方案,和不孕症诊断。
    方法:这是一项回顾性队列研究,研究了2015年5月至2019年9月在两个学术生育中心首次完成的IUI周期。通过预洗涤TMC对循环进行分层,产妇年龄,AMH水平,刺激方案,和不孕症诊断。主要结局是CPR,次要结局是活产和流产。
    结果:分析了一千一百五十四个周期。在导致CPR的162个周期中(14.0%),大多数人授精TMC>2000万。与TMC>2000万相比,对于较低的TMC类别,CPR或LBR没有差异,不包括TMC<200万组,其中没有怀孕。当TMC被分位数分层时,CPR和LBR也没有区别,包括最低十分位数(TMC0.09-860万)。当通过TMC分层时,年龄较小和较高的卵巢储备参数与较高的妊娠和LBR相关。当考虑不同的刺激方案时,妊娠和LBR没有差异。
    结论:我们的数据表明,妊娠和LBR在200万TMC以上是等效的。按TMC和患者参数分层的数据可用于指导进行ART的患者。
    OBJECTIVE: The purpose of this study is to clarify which pre-wash total motile count are associated with improved clinical pregnancy rate (CPR) and live birth rate (LBR) based on maternal age, AMH level, stimulation regimen, and infertility diagnosis.
    METHODS: This was a retrospective cohort study of first completed IUI cycles at two academic fertility centers from 5/2015 to 9/2019. Cycles were stratified by pre-wash TMC, maternal age, AMH level, stimulation regimen, and infertility diagnosis. The primary outcome was CPR and secondary outcomes were live birth and miscarriage.
    RESULTS: One thousand one hundred fifty-four cycles were analyzed. Of the 162 cycles that resulted in a CPR (14.0%), most had an insemination TMC > 20 million. Compared to TMC > 20 million, there was no difference in CPR or LBR for lower TMC categories, excluding the TMC < 2 million group, in which there were no pregnancies. When TMC was stratified by deciles, there was also no difference in CPR and LBR, including within the lowest decile (TMC 0.09-8.6 million). Younger age and higher ovarian reserve parameters were associated with higher pregnancy and LBR when stratified by TMC. There was no difference in pregnancy and LBR when considering different stimulation protocols.
    CONCLUSIONS: Our data suggest that pregnancy and LBR are equivalent above a TMC of 2 million. Data stratified by TMC and patient parameters can be used to counsel patients pursuing ART.

    OBJECTIVE: The aim of this study was to summarize the evidence of radiofrequency electromagnetic radiation (RF-EMR) exposure from wireless devices on total motile sperm count (TMSC) and identify gaps in the literature that could help clarify this link.
    METHODS: A literature search was conducted using PubMed/MEDLINE to find relevant studies examining the effects of EMR on male fertility, with a specific focus on TMSC, published from 2000 to 2019. R was used for data analyses.
    RESULTS: Motility was identified as the parameter linked to TMSC that was most negatively impacted by EMR exposure. Many gaps were found including geographic and lack of standardization with EMR factors such as exposure time and operating frequency.
    CONCLUSIONS: The EMR emitted by wireless devices may negatively affect TMSC, which is one of the better predictors of achieving pregnancies and impairs male fertility. Our findings highlight the need for clinicians to explore wireless device usage to help guide treatment decisions in men or couples with subfertility concerns.

    精子总数的阈值是多少,精子浓度,渐进运动,在进行生育力评估的夫妇中,总的进行性活动精子计数(TPMC)与较早的受孕时间有关?
    值远高于世界卫生组织(WHO)的精子总数参考,浓度,和渐进的运动,TPMC的价值高达1亿,始终与较早的受孕时间和较高的受孕率有关。
    虽然个别精液参数通常无法区分有生育能力的男性和不育男性,它们可以为寻求生育治疗的患者提供有关怀孕时间的临床有用信息。与常规精液参数相比,TPMC可能是评估男性不育严重程度的更好指标。
    我们使用了2002年至2017年对低生育能力男性进行的纵向队列研究的数据,并在研究中纳入了6061名进行初始精液分析(SA)的男性。
    纳入了在研究期间接受SA的低生育夫妇的男性,收集5年随访数据以获取受孕数据.夫妇被进一步分为两个亚组:自然受孕(n=5126),在分离使用ART或IUI实现受孕的人之后;没有主要女性因素的自然受孕(n=3753),在分离那些患有严重女性因素的不孕诊断后。通过将精液体积(ml)乘以精子浓度(百万/ml)和逐渐运动的精子百分比(%)来计算TPMC。Cox比例风险模型用于报告在调整男性年龄之前和之后具有95%CI的风险比(HR)。第一个SA之前的孩子数量,和收入。使用回归树方法,我们计算了精子总数的阈值,精子浓度,渐进运动,和TPMC可以最好地区分那些在第一次SA后5年内更有可能怀孕的人和那些不太可能怀孕的人。我们还绘制了精液参数的连续值,以预测5年受孕率和受孕时间。
    总的来说,中位受孕时间为22个月(95%CI:21-23).已知共有3957对(65%)夫妇在第一次SA的5年内实现了受孕。这些患者较年轻,精子浓度值较高,渐进运动,和TPMC。在整个队列中,由5千万分化最好的男性组成的TPMC,他们更有可能在5年内生孩子。在调整模型中,TPMC≥5000万的男性伴侣在5年内受孕的机会增加了45%(HR:1.45;95%CI:1.34-1.58),并且与TPMC<5000万的男性相比,怀孕时间更早(中位数为19个月(95%CI:18-20)与36个月(95%CI:32-41))。在自然受孕队列中观察到类似的结果。对于没有主要女性因素的自然受孕队列,TPMC的截止日期为2000万。在连续精液参数值的图形的视觉评估中,5年受孕率和受孕时间在精子浓度较高时始终稳定,精子总数,渐进运动,和TPMC与WHO参考水平和我们计算的阈值进行比较。对于TPMC,在曲线的视觉评估中,高达100-1.5亿的值仍然与更好的受孕率和受孕时间相关。
    关于女性伴侣的信息有限,并且在捕获不太严重的女性不孕症诊断方面可能存在不准确。此外,我们缺乏有关在我们的医疗保健网络之外获得的辅助怀孕的详细信息(在我们的队列中可能会误码为“自然概念”)。我们只使用最初的SA和精子形态,另一个潜在的重要参数,不包括在分析中。我们没有关于怀孕尝试/意图连续性的信息,这可能会影响受孕时间数据。最后,大多数夫妇在开始生育治疗之前已经尝试怀孕超过12个月,所以我们很可能低估了受孕时间。重要的是,我们的数据可能缺乏对其他人群的普适性.
    我们的结果表明,5千万精子的TPMC阈值提供了最好的预测能力,可以估计男性因素不育症夫妇的早期受孕时间。精子数较高,超过WHO参考的浓度和进行性运动仍与更好的受孕率和受孕时间相关.这为根据WHO参考值优化精液值低但不异常的精液参数提供了机会。当SA结果用于患者咨询时,这些数据可用于更好地告知患者每年受孕的机会。

    What thresholds for total sperm count, sperm concentration, progressive motility, and total progressive motile sperm count (TPMC) are associated with earlier time-to-conception in couples undergoing fertility evaluation?
    Values well above the World Health Organization (WHO) references for total sperm count, concentration, and progressive motility, and values up to 100 million for TPMC were consistently associated with earlier time-to-conception and higher conception rates.
    Although individual semen parameters are generally not able to distinguish between fertile and infertile men, they can provide clinically useful information on time-to-pregnancy for counseling patients seeking fertility treatment. Compared to the conventional semen parameters, TPMC might be a better index for evaluating the severity of male infertility.
    We used data from a longitudinal cohort study on subfertile men from 2002 to 2017 and included 6061 men with initial semen analysis (SA) in the study.
    Men from subfertile couples who underwent a SA within the study period were included, and 5-year follow-up data were collected to capture conception data. Couples were further categorized into two subgroups: natural conception (n = 5126), after separating those who achieved conception using ART or IUI; natural conception without major female factor (n = 3753), after separating those with severe female factor infertility diagnoses. TPMC was calculated by multiplying the semen volume (ml) by sperm concentration (million/ml) and the percentage of progressively motile sperm (%). Cox proportional hazard models were used to report hazard ratios (HRs) with 95% CIs before and after adjusting for male age, the number of previous children before the first SA, and income. Using the regression tree method, we calculated thresholds for total sperm count, sperm concentration, progressive motility, and TPMC to best differentiate those who were more likely to conceive within 5 years after first SA from those less likely to conceive. We also plotted continuous values of semen parameters in predicting 5-year conception rates and time-to-conception.
    Overall, the median time to conception was 22 months (95% CI: 21-23). A total of 3957 (65%) couples were known to have achieved conception within 5 years of the first SA. These patients were younger and had higher values of sperm concentration, progressive motility, and TPMC. In the overall cohort, a TPMC of 50 million best differentiated men who were more likely to father a child within 5 years. Partners of men with TPMC ≥50 million had a 45% greater chance of conception within 5 years in the adjusted model (HR: 1.45; 95% CI: 1.34-1.58) and achieved pregnancy earlier compared to those men with TPMC < 50 million (median 19 months (95% CI: 18-20) versus 36 months (95% CI: 32-41)). Similar results were observed in the natural conception cohort. For the natural conception cohort without major female factor, the TPMC cut-off was 20 million. In the visual assessment of the graphs for the continuous semen parameter values, 5-year conception rates and time-to-conception consistently plateaued at higher values of sperm concentration, total sperm count, progressive motility, and TPMC compared to the WHO reference levels and our calculated thresholds. For TPMC, values up to 100-150 million were still associated with a better conception rate and time-to-conception in the visual assessment of the curves.
    There was limited information on female partners and potential for inaccuracies in capturing less severe female infertility diagnoses. Also we lacked details on assisted pregnancies achieved outside of our healthcare network (with possible miscoding as \'natural conception\' in our cohort). We only used the initial SA and sperm morphology, another potentially important parameter, was not included in the analyses. We had no information on continuity of pregnancy attempts/intention, which could affect the time-to-conception data. Finally, most couples had been attempting conception for >12 months prior to initiating fertility treatment, so it is likely that we are underestimating time to conception. Importantly, our data might lack the generalizability to other populations.
    Our results suggest that a TPMC threshold of 50 million sperm provided the best predictive power to estimate earlier time-to-conception in couples evaluated for male factor infertility. Higher values of sperm count, concentration and progressive motility beyond the WHO references were still associated with better conception rates and time-to-conception. This provides an opportunity to optimize semen parameters in those with semen values that are low but not abnormal according to the WHO reference values. These data can be used to better inform patients regarding their chances of conception per year when SA results are used for patient counseling.

    目的:治疗特发性男性不育的最佳策略仍不清楚。这项研究的目的是评估抗氧化剂与几种维生素和补充剂联合治疗对精液参数的有效性。
    方法:通过Makler计数室评估的31名患有少精子症和/或弱精子症的男性被随机分配到两个治疗组:抗氧化剂补充剂的组合(L-肉碱,锌,虾青素,辅酶Q10,维生素C,维生素B12和维生素E)和中草药,hochu-ekki-to(HE)。血清内分泌概况和精液参数,尤其是活动精子总数,比较两组治疗前后12周的疗效。
    结果:在补充组中,内分泌检查结果无明显改善.精液体积的精液参数,精子浓度,精子活力无显著改善,而活动精子总数显著提高。相比之下,尽管精液浓度较高,但中药对内分泌因素或精液的发现均无明显改善,精液运动性,活动精子总数呈增加趋势。
    结论:因为联合抗氧化治疗可以显著改善特发性少弱精子症患者的精子活力,我们的补充剂可能是特发性男性不育症的一种治疗选择.
    OBJECTIVE: Optimal strategies to treat idiopathic male infertility have remained unclear. The aim of this study was to evaluate the effectiveness of combination antioxidant therapy with several vitamins and supplements on semen parameters.
    METHODS: Thirty-one men with oligozoospermia and/or asthenozoospermia evaluated by a Makler counting chamber were randomly assigned to two treatment groups: a combination of antioxidant supplements (L-carnitine, zinc, astaxanthin, coenzyme Q10, vitamin C, vitamin B12, and vitamin E) and a Chinese herbal medicine, hochu-ekki-to (HE). Serum endocrinological profiles and semen parameters, especially total motile sperm count, were compared between before and after 12 weeks of treatment in both groups.
    RESULTS: In the supplement group, endocrinological findings were not significantly improved. The semen parameters of semen volume, sperm concentration, and sperm motility were not statistically significantly improved, whereas total motile sperm count was significantly improved. In contrast, none of the endocrinological factors or semen findings were significantly improved by the Chinese herbal medicine although semen concentration, semen motility, and total motile sperm count showed a tendency to increase.
    CONCLUSIONS: Because combination antioxidant therapy could improve sperm motility significantly for patients with idiopathic oligoasthenozoospermia, our supplement could be one treatment option for idiopathic male infertility.

    It is crucial to identify the subfertile men with varicocele who will benefit the most from varicocelectomy, and the factors which help in predicting the response to varicocelectomy. We aimed to evaluate the impact of varicocelectomy on total motile sperm count (TMSC) and spontaneous pregnancy (SP) rates. A comprehensive literature search was performed using Medline/PubMed and Google Scholar up to December 26, 2018, with no restriction on language and year of publication. Published articles reporting different degrees of TMSC before and after varicocelectomy in infertile men with varicocele (palpable and/or clinical) were extracted. In addition, SP rates as a function of TMSC after varicocelectomy were reviewed. Potential biases were analyzed to rule out skewing factors. Mean TMSC was graded as: <2 million - profound, 2-5 million - severe, 5-10 million - moderate, and >10 million - mild. Data were analyzed using Stata11. Among the total 96 articles identified through electronic and manual searches of references, nine articles fulfilling the inclusion criteria were included. All degrees of TMSC resulted in a significant postoperative improvement, with only small differences, among the profound [10.20 million (95% confidence interval [CI]: 9.11-11.30, p < 0.0001)], severe [15.77 million (95% CI: 10.65-20.89, p < 0.0001)], and moderate groups [19.18 million (95% CI: 10.40-27.96, p < 0.0001)]. However, the mild group demonstrated a highly significant improvement [49.68 million (95% CI: 38.74-60.62, p < 0.0001)]. After varicocelectomy, the SP rate was highest in the TMSC >20 million group (55.4%), followed by TMSC 5-20 million group (45.4%), and TMSC <5 million group (26.3%). In comparison, the TMSC <1.5 million group demonstrated the lowest SP rate (16.0%). Moderate evidence suggests that varicocelectomy results in a significantly improved TMSC. The improvement in TMSC and SP rates is higher in patients who present a mild or moderate decreased TMSC.Abbreviations: TMSC: total motile sperm count; SP: spontaneous pregnancy; ART: assisted reproductive technology; IVF: in-vitro fertilization; IUI: intrauterine insemination; WMD: weighted mean difference; CI: confidence interval.
