Abstract Study question This study aimed to investigate the influence of lifestyle factors on sperm quality according to Motile Sperm Organelle Morphology Examination (MSOME) criteria. Summary answer The introduction of MSOME permits the examination of subcellular defect like nuclear vacuoles at hight magnification (6000x) in real time on vital sperm. What is known already It is increased accepted that lifestyle factors have an impact on sperm quality. Recent evidence shows that the selection of spermatozoa based on the analysis of morphology under high magnification may have a positive impact on embryo development in cases with severe male factor infertility and/or previous implantation failures. Therefore, MSOME has been considered as representing an improvement in the evaluation of semen quality. Although numerous studies have shown the influences of nutrition, lifestyle, age on semen quality, only very few study, have considered the influence of these factors on the vacuolization rate in semen analysis (MSOME criteria) Study design, size, duration The objective of this prospective study was to compare the semen parameters of 87 male patients undergoing evaluation or treatment of infertility at Unit of Pathophysiology of Reproduction ad PMA-Santa Maria Goretti Hospital -Latina according to MSOME and WHO (World Health Organization) criteria between January and September 2019.Written informed consent was obtained from all partecipant of this study. Participants/materials, setting, methods The subjects were divided into three groups according to age: Group 1 ≤ 35 yearş group II ,36–40 years; and Group III ≥ to 41 years .All patients filled a questionnaire answering questions regarding age, BMI, caffeine and alcohol consumptions, smoking and nutrition behavior. Were excluded from the study patients with chromosomal alteration. For multifactorial lifestyle influence patients were evaluated with a point base system with a cut-off >2 and cut off<3 for unhealthy style. Main results and the role of chance There was no difference between the groups with regard all semen parameters such as volume, concentration, number of leukocytes, morphology and vitality (%).The percentage of spermatozoa with LNV (Large Nuclear vacuoles) was significantly higher in the older group than in the younger (I and II) (39,14±13,74 vs 31,8±12 and 31,7 ±13,4 rispectively (p < 0,05)which does not correspond to a worsening of semen morphology. Regression analysis demonstrated a correlation between the percentage of spermatozoa with LNV and male age (r = –0,1) (p < 0,001). There was no correlation between lifestyle parameters ad enviroments factors . Comparing the semen parameters of healthy and unhealthy population we found no difference except a significantly higher number of spermatozoa with vacuoles in the unhealthy population (p < 0.001) Limitations, reasons for caution Although the sample examined in this study is limited in size and other studies are needed to confirm this evidence, the data available to us support the routine use of MSOME for ICSI and as a criterion for semen analysis with potential clinical repercussions. Wider implications of the findings: To date, there are few works in the literature that analyze the relationship between the morphology assessed with the MSOME and the age of the patients and the results are conflicting. To our knowledge many works agree with our results. Trial registration number Not applicable

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.

Lay summary Firefighters are occupationally exposed to heat intensities and chemical concentrations that may affect fertility. Twenty firefighters participated in an exploratory study assessing fertility of firefighters via an online survey and semen analysis. Data analysis included consideration of demographic characteristics, reproductive history and occupational exposures. Overall, firefighter semen parameters were below World Health Organisation reference values designating fertility in men. Firefighters younger than 45 years had a higher incidence of abnormal semen parameters (42%) than those aged 45 years or greater (9%). Increased rank and higher levels of occupational and/or personal hygiene were associated with improved semen quality. Increased frequency of fire exposure was associated with a reduction in normal forms, volume, sperm concentration and total sperm count. Sperm clumping was greater than 10% in 26% of samples, suggesting reduced semen quality. This exploratory study provides novel data that support the hypothesis of an association between semen quality and firefighter’s occupational exposure to toxic environments.

Abstract Objective: To evaluate the effect of acephalic spermatozoa syndrome on sperm quality in semen with different proportions of headless sperm.Design: Case control study.Setting: Andrology Laboratory.Patient(s): A total of 391 patients with headless sperm and 400 prenatal examination patients with no headless sperm who underwent semen analysis at the andrology laboratory.Intervention(s): None.Main Outcome Measure(s): The correlation of the proportion of headless sperm in semen with semen parameters.Result(s): All semen parameters except the semen volume were negatively (P<0.05) correlated with the proportion of headless sperm in the semen. The semen samples were divided into three groups based on the proportion of headless sperm (PHS) as follows: 0<PHS≤10% (n=249, group A), 10<PHS≤20% (n=71, group B) and PHS>20% (n=71, group C). Nearly all semen parameters were significantly lower in group B and group C than in the control group (P<0.05). However, in group A, only the vitality and motility parameters were lower than those of the control group.Conclusion(s): Semen samples containing headless sperm tend to have lower semen parameters than samples without headless sperm. Increases in the proportion of headless sperm in semen samples are associated with decreases in semen quality.

Ejaculatory Abstinence

Background: The precise effect of ejaculatory abstinence on semen parameters is highly debatable, especially among subfertile men. Previous studies on effect of abstinence time on different semen parameters have reported controversial results. The aim of this study was to retrospectively assess the variance of semen parameters with different periods of ejaculatory abstinence among both a population of normozoospermic ( n = 1621) and oligozoospermic ( n = 416) Tamil men, presenting to a fertility clinic for an infertility evaluation ( N = 2037). Materials and Methods: A retrospective analysis of 2037 semen analysis reports involved grouping patients based on their ejaculatory abstinence, that is, <24 h, 1 to 2 days, 3 to 7 days, 8 to 15 days, 16 to 30 days, and >30 days. All semen parameters were assessed as per the World Health Organization (WHO, 2010) recommended guidelines. The unpaired two-tailed t-test and Welch’s analysis of variance (ANOVA) combined with Games–Howell post hoc test were used for statistical analysis. A p value <0.05 was considered to be statistically significant. Result: A retrospective analysis of data ( N = 2037) identified no statistically significant differences in semen parameters of sperm concentration, percentage of progressively motile sperm, and normal sperm morphology in both normozoospermic and oligozoospermic individuals across different groups of abstinence. Semen volume was the only parameter that showed a statistically significant difference in both groups ( p < 0.0001). In both normozoospermic and oligozoospermic men, the group with <24 h abstinence had the highest mean percentage of progressively motile sperm and normal sperm morphology. Conclusion: The findings of this study suggest that ejaculatory abstinence may be highly arbitrary, and the recommendation of a strict 2- to 7-day abstinence per the WHO may be liberalized. In both normozoospermic and oligozoospermic men, semen parameters associated with an abstinence of <24 h were found to be noninferior as compared to longer ejaculatory abstinence intervals. These findings support in eliminating conservative recommendations as far as abstinence is concerned and suggest that patients may be asked to collect a semen sample on the day they present for an infertility evaluation, regardless of abstinence.

Poor sperm quality is one of the main factors of male infertility. Traditional Chinese Medicine (TCM) has been used frequently in clinical practice in many countries to treat a wide array of infertile problems. To further understand the effects of TCM on semen quality, we retrospectively enrolled patients with male infertility and poor semen quality at the Tainan Municipal Hospital in Taiwan between 2013 and 2016. Semen quality analysis in accordance with the WHO criteria is an essential step in the evaluation of male fertility status. Associations between the semen parameters and body mass index, smoking status, alcohol use, duration of infertility, and age were also analyzed. A total of 126 male infertility patients with abnormal semen analysis were included in this study: 50 TCM users and 13 TCM non-users. The basic characteristics of the two groups were not significantly different. TCM users account for 92.5% of the total semen improvement subjects. In conclusion, TCM supplementation may have a beneficial role as improving sperm quality for infertility patients.

Sperm Dysfunction

Male infertility, while having a variety of causes, is generally discussed in terms of semen parameters. While the World Health Organization (WHO) have been able io set limits for semen parameters below which a male can be considered subfertile (20 million/ml; >50% motility; >50% morphologically normal forms), it is well documented thatin vivoconceptions have been achieved where semen quality falls well outside these limits, and that infertile men may have normal semen parameters. Macleod and Gold in comparing 1000 fertile men and 1000 infertile men, found that significantly more infertile men had sperm densities below 20 million/ml, but also that 60% of infertile men had sperm densities of 60 million or more. Jouannet and Feneaux have shown that the conception ratein vivoonly apparently falls significantly at sperm concentrations of less than five million/ml. Although the cause of subnormal semen analysis is unknown in the majority of cases, there is no reason to suppose that abnormal semen parameters on their own are the cause of infertility. Rather the problem may be caused by failure of sufficient numbers of sperm traversing the female tract and reaching the oocyte. Unfortunately, lack of defined diagnoses lead to a lack of direct treatment for subnormal semen parameters. The development ofin vitrofertilization (IVF) resulted in a method that could be used to circumvent the problem since it requires relatively low numbers of sperm and these are placed in the immediate vicinity of the oocyte. It should also be pointed out that normal semen parameters do not imply fertility, since these parameters cannot directly identify dysfunction. IVF offers the advantage that sperm-oocyte interractions can be observed, and in cases of fertilization failure, the point at which sperm dysfunction manifests itself may potentially be identified – if not the nature of the dysfunction. Techniques have now been developed that may overcome certain types of dysfunction, using both biochemical and mechanical means.

Introduction: Infertility considered as a social and public health issue and estimated that most of these infertile couples are residents of developing countries. Infectious diseases including the history of Sexually Transmitted Infections (STIs) may impact on male reproductive function. Therefore, the present study aimed to investigate the prevalence of bacterial contaminants of semen and probable association with sperm quality of infertile men in Iranian population. Methods: The study population consisted of 200 infertile men and 150 fertile men attending an infertility Center in southwestern Iran during the study period in 2015. The assessment of sperm parameters was according to the World Health Organization (WHO) guidelines. The presumptive pathogens were identified using standard microbiology tests and confirmed by specific PCR primers. Results: The prevalence of bacteriospermia in the semen of the infertile group was significantly higher than that in the fertile group (48% vs. 26.7%, P <0.001). The microbiological analysis of samples showed that the most abundant species of bacteria in semen of infertile men were Chlamydia trachomatis (12.5%) followed by Neisseria gonorrhoeae (11%). On the other hand, in the control group, Lactobacillus spp. (17.3%) was the most isolated pathogen. Results showed that the presence of N. gonorrhoeae, C. trachomatis, Mycoplasma genitalium, Haemophilus, and Klebsiella was significantly associated with sperm abnormality. Conclusion: Based on our findings, it seems that bacteriospermia is associated with alterations in the properties of semen which may lead to a decrease in the fertilization potential of sperm. Therefore, immediate and appropriate treatment is necessary before investigating every other possible cause of infertility.

Objective: To quantify how many men with normal semen according to WHO (WHO - World Health Organization) 1999 criteria, should be considered with abnormal semen according to 2010 criteria and vice versa; to study which parameter of volume, concentration, motility and morphology is the most responsible of this change. Materials and methods: We studied, using WHO 1999 parameters, 529 consecutive semen samples from 427 men, collected in our Department from January 2008 to December 2009, then we re-evaluated those results using WHO 2010 parameters; we also studied each parameter to understand how changed the classification from normal (defined normal by all parameters) to abnormal (defined abnormal by at least one parameter) using the two WHO criteria. Results: 3 men (0.56%) were azoospermic. Among the remaining 526 samples, 199 (37.83%) were considered normal and 246 (46.76%) abnormal both according to WHO 1999 and WHO 2010 criteria; we found that none of the samples classified normal according to the previous criteria was classified abnormal according the more recent criteria, while 82 (15.58%) evaluated as abnormal according 1999 criteria changed to normal according 2010 criteria. The concordance between 1999 and 2010 evaluation was 84.44%. Conclusions: In this study we noted that the changes from WHO 1999 to WHO 2010 criteria did not modify the interpretation of semen quality, because comparing the two classifications we demonstrated that there is a substantial agreement, considering the three parameters (count, motility and morphology) all together, and also considering each single parameter. Anyhow, almost 16% of the patients considered infertile according to the old criteria, should be evaluated normal by the new classification and they should not need any treatment for infertility.

In order to evaluate the results of reproductive cows and heifers, different parameters of fertility are used, such as the service period, insemination index, intercalving time and others, and of the breeding bulls the values obtained through non-return. An ejaculate is taken up for further processing by veterinary centres only provided it meets the prescribed quality parameters. Rating semen parameters includes a macroscopic (volume, colour, consistency, smell and pH) and a microscopic evaluation (mobility, density, percentage of live sperm and abnormal and damaged sperm). In addition to sperm quality and the fertility of the female animal, the results of the non-return method are also influenced by a number of exogenous causes (season, age, race, insemination techniques) that have no small impact on the end result of insemination - pregnancy. In order to obtain more objective results of the fertility of bulls the following tasks were undertaken, namely: 1. to calculate with the non-return method the fertility of bulls in over 10,000 cows inseminated for the first time during a period of 6 years; and 2. to analyze the impact of semen quality, season, age of cow and bull, and the bull breed on the results of fertility.

A decades-long decline in sperm counts in Western countries has coincided with an increase in obesity rates, prompting study into their association. Few of these studies have incorporated men of color, the sperm health of whom is relatively unknown. The present exploratory study evaluated the association between body mass index (BMI), race, ethnicity, and sperm parameters among a diverse sample of U.S. men attending a Washington, DC physician practice. Semen samples were collected and processed at a single laboratory and sperm concentration, motility, morphology, and count were evaluated according to World Health Organization (WHO) 5th edition criteria. Multivariate models accounted for covariates related to sperm health. The study population ( n = 128) was largely obese (45.3%) or overweight (34.4%), and 36.0% were black or Hispanic. Black men had lower adjusted sperm concentration compared to white men (75.0 million/mL to 107.4 million/mL, p = .01) and were more likely to have oligozoospermia ( p = .01), asthenozoospermia ( p = .004), and low sperm count ( p < .0001). Hispanic men had higher adjusted sperm concentration compared to non-Hispanic men (124.5 million/mL to 62.1 million/mL, p = .007) and were less likely to have teratozoospermia ( p = .001). Obesity and BMI were associated with lower sperm motility and count in crude models only. Given the study’s sample size its findings should be interpreted with caution but align with the limited epidemiological literature to date that has evaluated racial and ethnic differences in semen quality. Heightened clinical research attention is needed to ensure men of color are included in representative numbers in studies of urologic and andrologic health.
