Among the possible risk factors for male reproduction, exposure to phthalates and alkylphenols is widely documented. This study evaluated the possible association between chemical exposure and the quality of the seminal fluid of 105 subjects in a fertility clinic. The urinary levels of seven phthalate metabolites (monoethylphthalate, MEP; monobenzylphthalate, MBzP; mono n-butylphthalate, MnBP; mono-(2-ethylhexyl) phthalate, MEHP; mono(2-ethyl-5-hydroxyhexyl) phthalate, MEHHP; mono-n-octylphthalate, MnOP; mono-isononylphthalate, MiNP) and bisphenol A (BPA), were analysed by high performance liquid chromatography/tandem mass spectrometry HPLC/MS/MS. The regression analysis showed that the semen volume was positively associated with MnBP, MnOP and BPA levels while was negatively associated with MiNP levels. The sperm concentration had a significant inverse relationship with MEP levels. A negative association was found between the use of plastic containers for food storage (p = 0.037) and semen volume (3.06 vs. 2.30 mL as average values, never vs daily). A significant positive correlation emerged (p < 0.005) between the consumption of canned food and the levels of BPA (2.81 vs. 0.14 µg/g creat as average values, daily vs. never) and between the use of perfumes and levels of MEP (389.86 vs. 48.68 µg/g creat, as average values, daily vs. never). No further statistically significant associations were found, even considering the working activity. Some evidence emerged about the possible link between exposure and seminal fluid quality: further case/control or prospective studies will allow us to confirm this causality hypothesis.

Infertility and problems of impaired fecundity have been a concern through ages and is also a significant clinical problem today, which affects 8–12% of couples worldwide. Of all infertility cases, approximately 40–50% is due to "male factor" infertility and as many as 2% of all men will exhibit suboptimal sperm parameters. It may be one or a combination of low sperm concentration, poor sperm motility, or abnormal morphology. Aim and objective: Demographic study of male infertility and assessment of abnormalities in semen parameters. Settings and Design: A cross-sectional study was conducted on 702 males who came to test for infertility to Saveetha Medical College and hospital to evaluate the parameters of semen and male infertility causes. Methods and Material: The participants were divided into two categories and one group was evaluated through a questionnaire for occupation, personal habits, exposure, family history, and the other category was evaluated on lab findings of various parameters to check the yearly variation in parameters of semen. Statistical analysis: Descriptive statistics. Results: On the evaluation of parameters of semen in combination with a questionnaire to 44 patients, it shows that alcoholics and smokers have low semen volume, increase in liquefaction time and increase in viscosity is most commonly seen in youngsters like students and IT professional. Conclusion: In our study low semen volume, delayed liquefaction time and increase in viscosity is most commonly seen in youngsters like students and IT professional with a history of alcohol and smoking and stress

Abstract Background The aim of this study was to provide information on the semen quality pattern of infertile men and age thresholds for semen parameters in China. Methods This was a retrospective cross-sectional study investigating 71,623 infertile men from the Reproductive and Genetic Hospital of CITIC Xiangya in Hunan, China, from 2011 to 2017. The Kruskal-Wallis test, Mann-Kendall test, linear regression model and joinpoint regression were used. Results Although erratic changes were observed in the median semen parameters (sperm concentration 40.1–52.1 × 106/ml, total sperm count 117.8–153.1 × 106, sperm progressive motility 33.4–38.1%) during the 7 years of observation, no significant decrease in semen quality was found, and 47.88% of infertile men showed normal semen parameters according to the World Health Organization (WHO) criteria. According to the joinpoint regression analysis, sperm progressive motility appeared to decrease earlier than the sperm concentration and total sperm count (at 28, 58, and 42 years of age, respectively). Conclusions There is no evidence of a deterioration in semen quality among infertile men in Hunan, China. Semen parameters decreased with increasing age, with turning points noted at different ages. Semen parameters are not absolute evidence for the assessment of male fertility potential. Therefore, we believe that, among semen parameters, the sperm concentration is the best predictor of fertility for ART, followed by motility. Decreased sperm motility may affect natural pregnancy, but it is not necessary for successful IVF.

Introduction: Semen analysis is an initial basic step in evaluating and diagnosing male infertility. Multiple risks factors in combination or alone are responsible for abnormal semen parameters. The present study aimed to study certain risk factors and semen parameters of infertile male. Methods: It was a descriptive cross-sectional study. We consecutively enrolled 186 male partners of infertile couple who underwent certain risk factors evaluation and semen analysis according to WHO guideline. Results: Multiple risk factors were present like Gulf country migration, smoking, chemical exposure and heat exposure in infertile male partners. Forty six percent of our patients were gulf workers. Eleven percent patients had azoospermia, 27% had abnormal sperm morphology and 23% had <25% motile spermatozoa. Conclusions: Surprisingly 46% of our patients were Gulf country workers and abnormal semen analysis is very important factor for infertility. Large prospective studies need to be carried out involving Gulf migrant workers only.

Abstract Background Recent studies suggest that serum vitamin D may be associated with semen parameters. In the present cross-sectional study, we attempted to investigate the association between serum vitamin D levels and semen parameters among Iranian sub-fertile men. Results A total of 350 infertile men recruited for this cross-sectional study using a simple random sampling method with a mean age of 34.77 years old, body mass index of 26.67 kg/m2, serum vitamin D of 20.17 ng/ml, semen volume of 3.82 mL, sperm count of 44.48 (106/mL), sperm total motility of 38.10 %, and morphologically normal sperm of 7.0 %. After controlling for potential confounders, serum vitamin D was positively associated with semen volume (β = 0.63, 95 % CI: 0.06, 1.20), sperm count (β = 14.40, 95 % CI: 4.56, 24.25), sperm total motility (β = 18.12, 95 % CI: 12.37, 23.86), and sperm normal morphology (β = 1.95, 95 % CI: 1.07, 2.83). Conclusions The present findings suggest that higher serum vitamin D levels are positively associated with higher semen volume, sperm count, sperm total motility, and normal morphology rate. These findings, however, do not specify a cause-and-effect relationship, and there is a need for further research in this area to understand whether vitamin D supplementation can improve semen parameters.

Data on the effect of obesity on seminal fluid and men fertility are inconsistent. The aim of this study was to evaluate the impact of body mass index (BMI) on semen characteristics in infertile men.A cross-sectional study was conducted on seventy-four infertile men who met inclusion criteria.Semen sample were collected and sperm concentration,progressive motility,total motility and normal sperm morphology were assessed in accordance with WHO 2010 criteria. For each patient weight and height were measure and patients were divided by BMI into normal weight (BMI: 18.5–24.9 kg/m2,n=30),overweight (BMI: 25–29.9 kg/m2,n=30) and obese (BMI:≥30 kg/m2, n=14). Seminal fluid parameters were compared among the three groups.Sperm concentration was lower in obese men but it did not differ significantly from those of normal weight and overweight infertile men (25.71±22.16,34.33±31.11,36.07±31.24 and million/ml respectively,P>0.05). Sperm progressive motility,total motility and normal sperm morphology also were not significantly different among normal weight,overweight and obese infertile men.Our findings suggest that BMI may have no influence on sperm concentration,motility and normal morphology in infertile men.

The influence of individual lifestyle factors is widely described in studies on semen quality. However, their synergistic effect is often neglected. The aim of the study was to examine the association between semen quality and dietary approaches to stop hypertension (DASH) diet, physical activity (PA), and the two separately and in combination. A cross-sectional study was carried out among 207 men aged 20–55. Dietary data were collected by a food frequency questionnaire (FFQ) and analysed according to the DASH scoring index. Physical activity was evaluated by the International Physical Activity Questionnaire. Semen parameters were assessed via the computer-aided semen analysis (CASA). Adherence to the DASH diet was associated with higher sperm count (ΔT3-T1 = 82.1 mln/ej) and concentration (ΔT3-T1 = 24.6 mln/mL). Higher PA was related to higher sperm count (ΔT3-T1 = 69.4 mln/ej), total (ΔT3-T1 = 11.9%), and progressive motility (ΔT3-T1 = 8.5%) and morphology (ΔT3-T1 = 2.8%) in the crude model and remained significant after adjustment. The combination of the DASH diet and PA, was significantly positively associated with sperm count (ΔT3-T1 = 98.1 mln/ej), sperm concentration (ΔT3-T1 = 17.5 mln/mL), total (ΔT3-T1 = 11.8%), and progressive motility (ΔT3-T1 = 10.0%) and morphology (ΔT3-T1 = 3.3%) in both models. Adherence to the DASH diet was related to higher sperm count and concentration, whereas after its combination with physical activity it was also positively correlated with sperm motility and morphology.

Background: Despite numerous reports about temporal changes in semen quality from all over the world, the debates continue. The latest systemic review has shown an overtime decrease in semen quality worldwide. Objective: To assess the temporal changes in the semen quality among Iranian population referred to an infertility center. Materials and Methods: In this retrospective cross-sectional study, semen parameters including concentration, motility, and morphology were compared between Iranian men reffered to Research and Clinical Center for Infertility, Yazd between 1990 to 1992 (group 1, n = 707) and 2010 to 2012 (group 2, n = 1108). Demographic characteristics and semen analysis were collected from the records. The effect of age on semen parameters was also investigated. Results: Despite the increase in sperm concentration l in group 2, sperm with normal morphology decreased significantly (p < 0.001). Grade-A motility decreased (p < 0.001), grade B motility increased (p < 0.001), and grade C and D motile sperm remained constant (p = 0.303 and p = 0.315, respectively). Also, no significant correlation between the age and semen parameters were observed. Conclusion: This study showed inconsistent temporal changes in the participant semen quality. Significant temporal decline were obtained between various semen parameters, sperm morphology and grade A motility. These results should be further evaluated by larger studies in the future. Key words: Infertility, Semen quality, Temporal changes.

Objective: The aim of this study was to investigate the effect of serum gonadotropin and total testosterone levels on semen parameters. Materials and Methods: Three hundred and eighty-two patients that applied to a male infertility polyclinic were included in our study. Serum gonadotropin and total testosterone levels and semen parameters of the patients were analyzed during the first visit to the clinic. The reference FSH value was 1.5-12.4 mIU/mL, that of LH was 1.7-8.6 mIU/mL and the reference value for total testosterone was 249-836 ng/dL. Results: While there was no statistically significant difference between the patients with low gonadotropin levels and the controls regarding any of the semen parameters (p &gt; 0.05), there was a strong statistically significant difference between the patients with high gonadotropin levels and the controls regarding sperm concentration (p = 0.000), total motility (p = 0.000), progressive motility (p = 0.000), and morphology (p = 0.000). There was a strong statistically significant difference between the patients with low testosterone levels and the controls regarding total motility (p = 0.012) and progressive motility (p = 0.010), and a weak statistically significant difference in morphology (p = 0.042). There was no statistically significant difference in semen volume or sperm concentration (p &gt; 0.05). There was no statistically significant difference in any of the semen parameters between the patients with high testosterone levels and the controls (p &gt; 0.05). Conclusions: Our findings especially regarding LH and T levels are not in agreement with previous reports. In this regard, there is a need for larger-scale and randomized trials to resolve this discrepancy.

Abstract Background: Iodine is an essential element for hormones synthesized by the human thyroid gland. Thyroid hormone deficiency affects all body tissues, including multiple endocrine changes that alter growth hormones, corticotrophin, glucocorticoids, and gonadal function. In many countries, subfertility is an important problem affecting about 10–15% of all couples trying to conceive. Male subfertile factors have accounted for 25–30% of all cases in their studies. The aim of this study was to study the correlation between urinary iodine concentration (UIC) and semen quality of fertile male in China.Methods: semen and urine samples were collected from males who attended a survey for the reproductive physiological constants of male and female in China. All participants were fertile and they should be free from diseases of male reproductive system and thyroid related diseases. We studied the correlation between UIC and semen quality parameters in fertile males and the effect of iodine concentration on male reproduction. Participants were divided into six groups based on UIC. We measured semen parameters and UIC. Semen parameters or time-to-pregnancy (TTP) were analyzed by Spearman correlation, linear regression and multivariable logistic regression. Results: 1089 men were recruited in the study. The mean and median age of participants were 27.46±0.12 and 27±3.88 years, respectively. UIC of 274 (25.16%) men was lower than the UIC of WHO recommended. UIC of 405 men located in the region of WHO recommended. 62.35% of them were not located in the optimal region. Semen concentration and total sperm count were found to decrease when UIC increases when the UIC≥100 ug/L. Conclusions: A male with deficient UIC or excessive UIC has more risk of lower semen quality such as sperm concentration and total sperm count. In addition, if a male with deficient UIC or excessive UIC, his wife has longer TTP than the males who had normal UIC. Deficient UIC associated with lower semen quality and TTP than excessive UIC.
