Objectives: The present study focused on tobacco smoke and its effect on semen parameters, sperm DNA quality (compaction and fragmentation) and clinical outcomes after intracytoplasmic sperm injection (ICSI) therapy Materials and Methods: The semen samples were divided according to smoking status into the following 2 groups, 98 heavy-smokers (G1) and 43 non-smokers (G2). Semen was prepared and purified using the PureSperm gradients according to the WHO guidelines 2010. Protamine deficiency (CMA3 positivity) was assessed by chromomycin CMA3 staining and sperm DNA fragmentation (sDF) by TUNEL assay. Results: The mean concentration and the total motility were significantly higher in G2 in comparison to G1 (P=0.014, and P=0.026 respectively) and the results were similar for the mean percent of the progressive motility and normal morphology (P=0.0001). CMA3+ and sDF in G2 were significantly lower in comparison to G1 (20.35 ± 13.34% vs. 33.30 ± 22.33%, P=0.001; 14.23 ± 13.07% vs. 26.68 ± 19.77%, P=0.0001). Meanwhile, there were no significant differences in the ICSI outcomes, except for the pregnancy rate, which was significantly higher in G2 than in G1 (0.60 ± 0.49% vs. 0.38 ± 0.48%; P=0.013). In G1, CMA3+ correlated negatively with sperm concentration (r=-0.233, P=0.021) but positively with sDF (r=0.484, P=0.0001). In G2, sDF correlated negatively with progressive motility and morphologically normal spermatozoa (r=-0.304, p=0.047; r=-0.361, P=0.017 respectively). Conclusions: The findings of this study revealed that tobacco smoking altered sperm parameters and later affected the pregnancy results in ICSI therapy. CMA3 and TUNEL tests are therefore useful as a supplementary test before any ART treatment to ensure a good prognosis.

AbstractBackgroundLead (Pb) is one of the metals most prevalent in the environment and is known to cause infertility and deoxyribonucleic acid (DNA) fragmentation. This study aimed to determine the association between seminal plasma Pb and sperm DNA fragmentation in men investigated for infertility.MethodsMale partners (n = 300) of couples investigated for infertility were recruited after informed consent was obtained. Sperm parameters were assessed according to the World Health Organization (WHO) guidelines. Seminal plasma Pb was estimated by atomic absorption spectrophotometry after digestion with nitric acid.ResultsIn Pb-positive and -negative groups the sperm parameters and sperm DNA fragmentation were compared using independent sample t-test and the Mann-Whitney U-test, respectively. The mean [standard deviation (SD)] age and duration of infertility were 34.8 (5.34) years and 45.7 (35.09) months, respectively, and the mean Pb concentration was 15.7 μg/dL. In Pb positives compared to Pb negatives the means (SD) of sperm count, progressive motility viability and normal morphology were lower (p > 0.05) but the DNA fragmentation was significantly higher 39.80% (25.08) than Pb negatives 22.65% (11.30). Seminal plasma Pb concentration and sperm DNA fragmentation had a positive correlation (r = 0.38, p = 0.03). A negative correlation was observed between sperm DNA fragmentation and sperm concentration, progressive motility, total motility and viability. When the DNA fragmentation was ≥30% sperm concentration and viability decreased (p < 0.05).ConclusionsPb in seminal plasma had a significant effect on sperm DNA fragmentation but not with other sperm parameters.

AIM: This study aimed to assess the difference in sperm concentration, total motility, progressive motility, and deoxyribonucleic acid (DNA) fragmentation index (DFI) before and after processing with 5 and 10 min swim-up (SU). METHODS: Fifty patients who met the study inclusion criteria from June 2020 to October 2020 were subjected to routine semen and sperm DNA fragmentation analysis. Each of the samples was then divided into three tubes, one as control and the others were processed using the SU method with 5 and 10 min centrifugation time, respectively. After being processed, the samples were subjected again to routine semen and sperm DNA fragmentation analysis. The results were being compared among three groups. RESULTS: The sperm concentration after 5 and 10 min SU (27.78–39.79 and 35.36–51.09, respectively; p < 0.05) was significantly higher compared to fresh semen (24.85–32.33). The total motility before and after 5 and 10 min SU were 43.78–51.08, 97.66–98.20, and 97.86–98.20, respectively. The progressive motility after 5 and 10 min SU (0–41 and 0–54, respectively) was significantly higher than fresh semen (0–24; p < 0.05). The DFI was significantly better after 5 min SU (3.82–6.98) compared to fresh semen and after 10 min SU (13.48–19.04 and 1–25, respectively; p < 0.05). CONCLUSION: Prolonged centrifugation time may yield a higher number of sperm concentration and motility, but it may also lead to a higher DFI. Hence, a shorter centrifugation time should be used for a better semen quality intended for assisted reproductive technologies.

Introduction. According to the WHO data, depression is a common disease among women and men of reproductive age. One line of the correction of depressive disorders is selective serotonin reuptake inhibitors (SSRIs). The ingestions have shown that using SSRIs harms sperm quality. The literature date of evaluation of male fertility after discontinuation of antidepressants is quite limited.Purpose of the study. To evaluate the influence of Fluoxetine intake on semen parameters, sperm DNA fragmentation and hormonal status.Materials and methods. Twenty-five men (mean age - 35.2 ± 4.5 yo) with depression were included in the study. Fluoxetine (20 mg per day) was prescribed to all the patients for 12 wk. Semen parameters, sperm DNA fragmentation, sex hormones levels were measured before-after treatment and 3 mo behind discontinuation.Results. After 12 weeks of the treatment the mean semen volume decreased from 3.1 ± 0.7 to 2.9 ± 0.7 ml (p = 0.638), sperm concentration - from 39.4 ± 18.5 to 34.3 ± 16.8 mln/ml (p = 0.384), sperm motility decreased from 41.7 ± 7.6 to 35.5 ± 7.8% (p < 0.05), the mean percent of normal morphology form - from с 12.7 ± 2.8 to 10.7 ± 2.2% (p < 0.001). Sperm DNA fragmentation increased 16.2 ± 4.9 to 22.2 ± 4.3% (p < 0.001). The mean semen volume, sperm concentration, motility, percentage of normal morphology increased and reverted to the normal levels after 3 mounts of drug discontinuation. Sperm DNA fragmentation index decreased, and it had the values less than before the treatment that positively correlated with the reduction of depression's symptoms. It was not significant dynamics in hormonal parameters before and after the therapy.Conclusion. Using fluoxetine has a reversible negative effect on male fertility. It is important to inform the patients about the temporary side effects of SSRIs in fatherhood planning cases.

Recently, a new procedure for the analysis of sperm DNA fragmentation has been developed for humans and different mammalian species, using a commercial kit based on the sperm chromatin dispersion (SCD) test; however, a descriptive study in canine semen has not been performed. The aim of this work was to assess the sperm DNA fragmentation in canine ejaculates using the SCD test and 2 different staining techniques. For this purpose, ejaculates were collectedby digital manipulation from4 healthy dogs of different breeds (1 German Pointer, 2 Spanish Greyhounds, and 1 Crossbreed). After collection, the sperm-rich fraction of the ejaculates from 3 dogs were pooled each time (n = 4) and then extended in Dulbecco’s phosphate buffered saline. All the pooled semen samples presented physiological values concerning routine semen parameters (motility, morphology, and sperm concentration). The sperm DNA fragmentation was assessed using the Sperm-Halomax® commercial kit specifically developed for canine semen (Halotech DNA SL, Madrid, Spain). Two semen aliquots of the diluted pooled semen samples were processed on each pre-treated slide provided in the kit following the manufacturer’s instructions. The last step was the staining technique. We stained each slide with 2 different staining procedures. The first half of the slide was stained with propidium iodide (Sigma-Aldrich, St. Louis, MO, USA) mixed in a proportion 1 : 1 with an antifading solution. The second half of the slide was stained for 15 min in Wright solution (1.01383.0500, Merck, Whitehouse Station, NJ, USA) 1 :1 in Phosphate Buffer pH 6.88 (1.07294.1000, Merck). The stained slides were observed using fluorescence and light microscopy, respectively. Five hundred sperm per slide were counted. Spermatozoa with fragmented DNA showed a large and spotty halo of chromatin dispersion. Unfragmented sperm only showed a small and compact halo. Statistical analyses were performed using the Statistical Package for Social Science version 12.0 (SPSS Inc., Chicago, IL, USA). The sperm DNA fragmentation index was compared between Wright and fluorescence staining methods by ANOVA. Results were expressed as mean ± standard error of the mean. The first report of the sperm DNA fragmentation index in canine ejaculates was 2.26 ± 0.53% for Wright staining and 1.99 ± 0.10% for fluorescence technique. No differences were found between staining procedures. In conclusion, it was possible to assess the sperm DNA fragmentation of canine ejaculates using 2 different staining procedures, expecting that continuous research could be useful in defining the role of DNA fragmentation SCD test in canine semen evaluation and cryopreservation.

Because the assessment of sperm DNA fragmentation (SDF) plays a key role in male fertility, our study was designed to find the relationships between SDF and standard semen parameters. The receiver operating characteristic (ROC) curve showed that 18% SDF is a prognostic parameter for discriminating between men with normal and abnormal standard semen parameters (n = 667). Men with > 18% SDF had significantly lower quality semen, a higher prevalence of abnormal semen characteristics, and a higher odds ratio for abnormal semen parameters compared to men with ≤ 18% SDF. An ROC analysis provided predictive values for age and semen parameters to distinguish between men with SDF > 18% and men with ≤ 18% SDF. SDF was positively correlated with male age and teratozoospermia index but negatively with sperm concentration, total number of spermatozoa, sperm morphology, progressive motility, and vitality. Our study shows that 18% SDF has a predictive value for distinguishing between men with normal and abnormal semen characteristics. Men with >18% SDF have a higher risk for abnormal semen parameters, while age and obtained semen parameters have a predictive value for SDF. There is a relationship between SDF and conventional sperm characteristics, and thus, SDF can be incorporated into male fertility assessment.

Introduction. The concept of seasonal variability of sperm parameters is controversial. However, it should be considered during medical evaluation and solicitation of sperm donors. Aim. To evaluate seasonal variability of sperm parameters from anonymous sperm donors in a reproductive medicine center. Materials and methods. A retrospective study of 1252 semen samples from 39 sperm donors (mean age 27.1 ± 3.9 years) in a reproductive medicine center in Saint Petersburg during the period from October 1, 2015 to October 1, 2017 was performed according to WHO 2010 recommendations. Semen volume, sperm concentration, total sperm number, progressive motility, and number of progressively motile sperm were analyzed. Results. Individual variability in semen parameters was high. The mean ejaculate volume in the summer months was higher than in the autumn, winter, and spring (t = 3.65, p < 0.001; t = 4.18, p < 0.0001; t = 1.92, p = 0.056 respectively). The lowest volume (2.83 ± 1.32 ml) was registered in January. The mean sperm concentration in summer was lower than in autumn, winter, and spring (t = 3.65, p < 0.001; t = 4.18, p < 0.0001; t = 1.92, p = 0.056 respectively). It was higher in winter than in spring and autumn (t = 2.54, p = 0.012; t = 1.72, p = 0.082 respectively). The highest mean sperm concentration was registered in January and the lowest in July (157.2 ± 46.6 and 131.9 ± 44.0 million sperm per ml, respectively). No significant seasonal differences were found in total sperm number, progressive motility, or number of progressively motile sperm (p > 0.1). Conclusions. The study suggests there is both individual and seasonal variability in sperm donors’ semen parameters. As several semen samples are needed to rate semen quality, we recommend that semen analysis for a potential sperm donor be performed in the summer months.

Abstract Background: Several studies have explored the relation between traditional semen parameters, sperm DNA fragmentation (SDF), and unexplained recurrent miscarriage (RM), but these findings remain controversial. Hence, we conducted this meta-analysis to explore the relation between traditional semen parameters, SDF, and unexplained RM. Methods: Multiple databases including PubMed, Google Scholar, MEDLINE, EMBASE, Cochrane Library, Web of Science databases, and China National Knowledge Infrastructure (CNKI) were searched to identify relevant publications. From the eligible publications, data were extracted independently by two researchers. The heterogeneity between publications was calculated using the I2 statistics and Cochran’s Q test. Statistical analyses were conducted using Stata/SE 12.0 (StataCorp, College Station, Texas, USA). Based on heterogeneity assessment, random- or fixed-effects models were selected to calculate the weighted mean differences (WMDs) and their corresponding 95% confidence intervals (CIs). To estimate the stability of the pooled results, a sensitivity analysis was conducted by excluding each study. To estimate the possible publication bias, Egger’s regression test and Begg’s funnel plot were used. Results: A total of 280 publications were produced using the search strategy. According to the inclusion/exclusion criteria, 19 publications were eligible. A total of 1182 couples with unexplained RM and 1231 couples without RM were included in this meta-analysis to assess the relation between traditional semen parameters, SDF, and unexplained RM. Our results showed that couples with unexplained RM had significantly increased levels of SDF (WMD=8.77, 95% CI=4.03 to 13.51, P<0.001) and significantly decreased levels of progressive motility (WMD=-4.75, 95% CI=-8.35 to -1.15, P<0.05) and total motility (WMD=-10.30, 95% CI=-15.03 to -5.57, P<0.05) than those of couples without RM, but not significantly different in volume (WMD=-0.12, 95% CI=-0.32 to 0.08, P>0.05), sperm concentration (WMD=-2.28, 95% CI=-4.58 to 0.02, P>0.05) and total sperm count (WMD=-10.73, 95% CI=-22.11 to 0.66, P>0.05) between couples with and without RM.Conclusion: Couples with unexplained RM had significantly increased levels of SDF and significantly decreased levels of progressive motility and total motility than those of couples without RM. SDF assay may be considered as part of the evaluation of couples with unexplained RM.

Objective: the aim of our study was to put forward insights to treat any possible correlation among sperm quality, sperm DNA damage and male age as they may have fertility implications for men who choose to delay fatherhood. Materials and methods: Our study is a non-interventional retrospective analysis of 3124 semen samples from patients that were investigated for the conventional semen parameters. Tunel test assay was set up for the evaluation of the sperm DNA fragmentation index (DFI). We applied the Kappa index to compare both the 1999 and the 2010 World Health Organization (WHO) reference criteria to evaluate the competence of such semen parameters categorization during the standard routine of our laboratory. Results: With regards to our findings, it is possible to underline a significant relationship between aging and semen volume (p = 0.001), motility (p = 0.009), semen viscosity (p < 0.003) and sperm DNA damage (p < 0.009). We found a trend when focusing on the semen concentration (p = 0.05). The analysis of sperm morphology did not show any influence with advancing age (p = 0.606). When comparing both the 1999 and the 2010 WHO scales we found no accordance in the appraisal of sperm morphology but a very good one in the evaluation of the other parameters. Conclusions: Conventional semen analysis represents the opportunity to draw up a proxy insight on the male fertility status even if semen quality can only indirectly assess the probability of pregnancy. Several studies have verified a decay in the male reproductive system, sperm quality and fertility with advancing age although the reported results are not yet conclusive. Our results substantially agree with those findings outlined in the literature. Moreover we find that the discrepancy between the two WHO reference scales would eventually lead to an improper diagnosis of infertility.

Abstract Background Although bacterial infections have been recognized as a possible cause of male infertility, the effect of bacterial infections on sperm quality and sperm DNA fragmentation remains controversial. The current study aimed to investigate the prevalence rate of bacterial infection in subfertile men and its effect on semen quality. Seminal fluid was collected from 172 male members of infertile couples attending the andrology infertility center and a group of 35 fertile subjects as a control. Sperm parameters and DNA fragmentation were evaluated based on the type of bacteria in all ejaculates. Results From the 172 patients investigated for infertility, 60 (34.88%) patients had a positive culture for pathogenic bacteria of different species. Leukocytospermia was significantly higher in infected samples in comparison with non-infected samples (p < 0.05). Sperm concentration and motility and morphology were significantly lower in infected than non-infected samples. Moreover, sperm DNA fragmentation was significantly higher in infected than non-infected samples. Besides, our results showed that sperm DNA fragmentation was correlated significantly with leukocytospermia (R: 0.22, p < 0.01). Conclusion The present study suggested that bacterial infection significantly correlated with leukocytospermia could impair male fertility potential through decreasing sperm motility, morphology, and DNA integrity.
