Abstract
A variety of parameters, including liquefaction and semen viscosity, affect the sperm's ability to travel and reach the egg for fertilization and conception. Given that the details behind the viscosity of the semen in male camels have not yet been fully clarified, the purpose of this study was to ascertain how the addition of papain affected the viscosity of fresh diluted camel semen. The study examined semen samples derived from camels that had distinct viscosities. Sperm motility, viability, abnormal sperm percentage, concentration, viscosity, morphometry, acrosome integrity and liquefaction were among the evaluations following 0, 5, 10, 20 or 30 min of incubation at 37°C with papain (0.004 mg/mL, 0.04 mg/mL or 0.4 mg/mL; a semen sample without papain was used as a control). A statistically significant interaction between the effects of papain concentrations and incubation time was found (F = 41.68, p = .0001). Papain concentrations (p = .0001) and incubation times (p = .0001) both had a statistically significant impact on viscosity, according to a simple main effects analysis. A lower viscosity was found (p < .05) at 0.04 mg/mL (0.1 ± 0.0) after 10 min of incubation. A simple main effects analysis showed that papain concentrations and incubation time have a statistically significant effect on sperm motility (p = .0001). At 0.04 mg/mL papain, the sperm motility % was higher (p < .05) after 10 min (64.4 ± 4.8), 20 min (68.4 ± 6.2), and 30 min incubation (72.2 ± 6.6) compared to 0, 5 min (38.3 ± 4.1 and 51.6 ± 5.0, respectively). In conclusion, the fresh diluted camel semen had the lowest viscosity properties after 10 min of incubation with 0.04 mg/mL papain, without compromising sperm motility, viability, acrosome integrity and sperm morphology.

Abstract
Background Seminal hyperviscosity has been shown to be associated with male infertility. The aim of this study was to assess the prevalence of hyperviscosity in semen of Malawian males seeking infertility treatment. Methods A total of 120 men visiting our laboratory for fertility assessment donated semen samples. The semen samples were assessed for hyperviscosity, volume, concentration, total motility, progressive motility, viability, and morphology. Results Out of the 120 samples analyzed, 34 samples were hyperviscous representing 28.3%. No significant statistical difference in semen volume between samples with normal viscosity compared to those with hyperviscosity (p>0.05). Sperm concentration, progressive motility, total motility, viability, and normal morphology were significantly higher in the normal viscosity group when compared to the abnormal viscocity group (p<0.05). Conclusion Hyperviscosity affects a significant number of men in Malawi and may be the cause of decreased fertility as it was associated with poor sperm concentration, total motility, progressive motility, viability, and morphology.

Abstract
OBJECTIVES Solvent exposure is among the most common occupational exposures to chemical toxicants; data about the impact of such exposure on semen parameters are contradictory. We conducted the first meta-analysis to evaluate the risk of alteration in semen parameters related to occupational exposure to solvents. METHODS From the PubMed database, we selected studies analyzing the semen of subjects occupationally exposed to solvents, compared with unexposed controls. The meta-analysis was performed on the various semen parameters analyzed in both populations. RESULTS Seven studies were included in the study. The meta-analysis revealed a significant decrease in ejaculate volume [standardized mean difference (SMD) = -0.35 (-0.63 to -0.07)] and sperm concentration [SMD = -0.36 (-0.64 to -0.08)] in workers exposed to solvents compared with unexposed controls. CONCLUSION Our results highlight the importance of preventing reprotoxic risks to male fertility in the workplace.

Abstract
Background/Aims Semen hyperviscosity (SHV) is one of the significant factors involved in poor semen quality and male infertility. It also leads major problems during assisted reproduction techniques and in vitro fertilization process. Although influence of SHV on sperm quality, fertilization rate and male infertility have been widely considered, molecular and cellular mechanisms for these abnormalities are not well understood. In this review, we aimed to discuss the proposed cellular and molecular mechanisms of SHV on male reproductive system, the importance of oxidative stress (OS) and the mechanisms by which SHV induces OS and impairment of other antioxidants. Methods A PubMed/Medline and EM-BASE search was performed using keywords: "hyperviscosity semen", "oxidative stress", and "male infertility". Conclusion OS induced by reactive oxygen species can be considered as a major mechanism in patients with hyperviscosity semen that is associated with DNA fragmentation, lipid peroxidation and sperm membrane disintegrity, apoptosis, depletion of antioxidants, and subsequently poor sperm quality and male infertility. Therefore, antioxidant therapy may improve main pathological effects of hyperviscosity semen, especially oxidative damages and inflammation, on sperm quality and function. Further, randomized controlled studies are necessary to confirm these results and make a comparison between effects of various antioxidants such as N-acethyl-cysteine and Curcumin on fertility problem in patients with hyperviscous semen.

Abstract
Semen hyperviscosity (SHV) is one of the factors involved in deficiency in sperm function. This research aimed to evaluate seminal plasma total antioxidant capacity (TAC)
and malondialdehyde (MDA) levels in infertile patients with hyperviscous and non-hyperviscous semen samples to understand whether hyperviscous semen is associated with
oxidative damage in infertile subjects. In this cross sectional study, 59 semen samples
were provided by fertile (n=12) individuals as control, infertile patients with normal viscosity (n=25) and infertile patients with hyperviscosity (n=22). After semen parameters examination, semen viscosity was studied by glass pipettes. Seminal plasma TAC and MDA
levels were measured by ferric reducing of antioxidant power (FRAP) and thiobarbituric
acid reaction (TBAR) methods, respectively. A probability less than 0.05 was considered
statistically significant throughout the article. The mean of sperm parameters including:
counts, motility and normal morphology in patients with hyperviscosity were significantly
lower than those in non-hyperviscosity patients (p<0.05, p<0.01 and p<0.001, respectively). The mean of seminal plasma TAC value in seminal plasma of non-hyperviscosity
patients (1710.31 ± 458.67 µmol/l) was significantly (p<0.01) higher than that of hyperviscosity group (1230.25 ± 352 µmol/l). A trend toward a higher mean of seminal plasma
MDA value was estimated for hyperviscous group compared with non-hyperviscous (1.01
± 0.41 nmol/ml vs. 0.94 ± 0.28 nmol/l); however, it was nonsignificant. Hyperviscous semen impairs seminal plasma TAC which is eventually associated with sperm membrane
lipid peroxidation.

Abstract
Quantification of ATP content in spermatozoa is a useful assay for evaluating sperm function; however, most detection methodology relies on assessing single samples. We have developed and validated a highly repeatable assay that permits simultaneous measurement of up to 78 samples. A key feature of this assay includes combination of a phosphatase inhibition and ATP extraction step that permits maximal detection of ATP and sample storage at -20 degrees C prior to assay. The assay was validated for spermatozoa from three different species, including turkey, rooster and boar. The sensitivity of the assay differed between avian and mammalian spermatozoa, with 2.5 x 10(6) spermatozoa being the lowest number of turkey and rooster spermatozoa that could be assayed compared to 2.5 x 10(5) boar spermatozoa. Concentrations of ATP in fresh turkey semen ranged from 2.14 to 15.6 nmol/10(9) spermatozoa; similarly, freshly collected rooster semen contained from 2.16 to 21.4 nmol ATP/10(9) spermatozoa. Evaluation of turkey semen that had been stored at 4 degrees C for 24 h revealed a decline in ATP concentrations (2.35 +/- 0.34 nmol ATP/10(9) spermatozoa). Likewise, cryopreserved rooster spermatozoa contained lower concentrations of ATP (0.05 +/- 0.01 nmol ATP/10(9) spermatozoa) than non-stored spermatozoa. Boar spermatozoa contained similar concentrations of ATP, whether fresh (74.2 +/- 8.1 pmol ATP/10(6) spermatozoa), stored for 1 day (77.0 +/- 8.1 pmol ATP/10(6) spermatozoa) or 5 days (81.96 +/- 8.1 pmol ATP/10(6) spermatozoa). For all three species, assay variation was low (inter-assay, 0.66-1.9% CV; intra-assay, 1.3% CV).

Abstract
Seminal viscopathy was shown to be associated with male infertility. However, our knowledge about the regulatory mechanism of this process is still limited. In semen samples from 411 men attending for fertility assessment, traditional semen parameters including visco-elasticity were assessed according to the World Health Organization guidelines. Sperm motility was evaluated by use of computer aided sperm analysis (CASA). Seminal activity of neutral alpha-glucosidase (NAG) and concentrations of prostate-specific antigen (PSA), zinc, and fructose were measured. The activity of NAG, and the concentrations of PSA and zinc were significantly lower in hyper-visco-elastic semen samples (medians: 5 vs. 8 mU/mL; 741 vs. 924 mg/L; 1 vs. 2 mM/L), than in those with normal visco-elasticity (p = 0.004, 0.005 and 0.011, respectively). When comparing the total amounts, only for seminal fructose there was a difference between samples with high visco-elasticity as compared with those of normal visco-elasticity (median: 74 vs. 53 microM/ejaculate, p = 0.007) This seminal marker was the only significant independent parameter in predicting seminal visco-elasticity in a multiple logistic regression analysis (odds ratio for the highest quartile = 4.67). Hyper-visco-elasticity was associated with a lower percentage of motile spermatozoa (43 vs. 50%, p = 0.045). Similar trend was found for the CASA motility characteristics curvilinear velocity (VCL), average path length (VAP), amplitude of lateral head displacement (ALH) (p = 0.008, 0.038 and 0.020, respectively). Our study demonstrated the interplay between the regulatory effect of post-testicular organs on semen visco-elasticity. Hyper-visco-elasticity was associated with asthenozoospermia and lower levels of VCL, VAP and ALH.

Abstract
OBJECTIVE To determine whether occupational exposure of men to hydrocarbons has adverse effects on the quality of their semen. DESIGN Comparative study. SETTING The rubber industry in Mexico City. PATIENT(S) Forty-eight workers who were exposed to hydrocarbons for 2-24 years and 42 unexposed workers. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Environmental hydrocarbon concentrations were determined by continuous air monitoring in all areas of the factory. Analyses of semen samples were performed in accordance with World Health Organization criteria. RESULT(S) Hydrocarbon concentrations were as follows: ethylbenzene, 220.7-234 mg/m3; benzene, 31.9-47.8 mg/m3; toluene, 189.7-212.5 mg/m3; and xylene, 47-56.4 mg/m3. The number of subjects with ejaculates that had normal characteristics was greater in the unexposed group (76%) than in the exposed group (17%). More abnormal characteristics were found in the semen of exposed workers than unexposed workers, including alterations in viscosity, liquefaction capacity, sperm count, sperm motility, and the proportion of sperm with normal morphology. Some abnormal characteristics correlated with the number of years of exposure to the hydrocarbons. CONCLUSION(S) Damage to the spermatogenic process resulting from hydrocarbon exposure was demonstrated by an increased rate of abnormalities in the semen of exposed workers compared with unexposed workers. This information may be useful for conducting future analyses of reproductive risks related to exposure to high concentrations of hydrocarbons.
