Comparison of the Sperm Quality Analyzer IIC variables with the computer-aided sperm analysis estimates

Sperm Quality Analyzer (SQA) IIC, an upgrade version, is an inexpensive device and provides a quantitative estimation of sperm motility, whereas the use of computer-aided sperm analysis (CASA) provides high precision and provision of quantitative data on sperm kinetics. The aim of the present study was to evaluate if the SQA IIC variables correlated with the CASA estimates. Semen quality analysis of 71 fresh semen samples was performed using SQA IIC and CASA. Total sperm concentration, percentage of progressively motile sperm, percentage of normal morphology, motile sperm concentration, sperm motility index (SMI) and functional sperm count (FSC) determinations were performed using SQA IIC. Sperm concentration, sperm motility, and sperm motion variables including amplitude of lateral head displacement (ALH), beat cross frequency (BCF), curvilinear velocity (VCL), straight line velocity (VSL), average path velocity (VAP), linearity (LIN=VSL/VCL), and straightness (STR=VSL/VAP) were evaluated simultaneously on the same semen samples using CASA. The sperm characteristics were compared between SQA IIC and CASA. There were significant correlations of sperm concentration (r=0.634, p < 0.0001), sperm motility (r=0.697, p < 0.0001), and motile sperm concentration (r=0.757, p < 0.0001) between the two devices. Both SMI and FSC significantly correlated with eight CASA estimates, including sperm concentration, sperm motility, motile sperm concentration, ALH, VCL, VSL, VAP, and Rapid. SQA IIC is simple and easy to use. Moreover, the SQA IIC variables well correlated with the CASA estimates. As a screening test for semen quality, SQA IIC is considered as useful in the management of male infertility.     

CASA as an aid to selecting sperm suspensions for artificial insemination in Callithrix jacchus

The ability to use sperm motility parameters, obtained by computer-assisted sperm motility analysis (CASA), as an aid to selecting sperm samples for artificial insemination (AI) would have considerable benefits for commercial organizations and for the captive breeding of endangered species. In this study the Hobson sperm tracker (HST) was validated for use with spermatozoa from Callithrix jacchus, the common marmoset, by comparing values for straight line velocity by CASA with those obtained by direct measurement of sperm tracks. Using the settings established during validation, ejaculated and epididymal spermatozoa were analysed with the HST. The range of values for velocity parameters were used to establish expected motility profiles for the two types of spermatozoa as follows: for epididymal spermatozoa (concentration 2.2 - 85.8 x 10(6) spermatozoa/mL) VCL 109.8-155.9, VSL 75.2-141.5, VAP 85.8-142.1, MAD 13.7-40.7, ALH 3.8-7.8, BCF 1.4-4.2, LIN 40.5-91.1% and STR 70.1-97.1%; for ejaculated spermatozoa (concentration 3.2-82.0 x 10(6) spermatozoa/mL) VCL 89.6-136.7, VSL 69.6-110.3, VAP 74.5-121.9, MAD 19.2-29.3, ALH 3.0-9.9, BCF 2.8-5.5., LIN 65.4-85.3% and STR 93.8-97.7%. Epididymal spermatozoa from males which were not sexually active had significantly lower values for VCL, VSL and VAP, while values for MAD were significantly higher than for spermatozoa from sexually active males (p < 0.031). Sperm concentration affected motility parameters significantly. Although motility parameters differed according to the batch of medium used, the differences were not statistically significant. Epididymal sperm samples had significantly higher VCL, VSL and VAP but lower BCF and LIN than ejaculated sperm samples of the same concentration diluted in the same batch of medium, while MAD, ALH and STR were not different. Urine contamination significantly reduced VCL, VSL and VAP (p < 0.008, < 0.016 and < 0.008, respectively, sample size = 7) whereas MAD, ALH, BCF, LIN and STR were not affected. Therefore CASA could be useful in screening ejaculates for use in Al to eliminate samples with unusual motility patterns.

不同海拔高度成年男性精子参数的比较

目的:了解不同海拔长期缺氧暴露对男性精子功能的影响。方法:以驻留海拔5340m1～3年的28例健康男性青年为高海拔组,以34例现驻平均海拔3800m2～5年的健康男性青年为中海拔组,对照组为31例常年生活在1300m海拔地区的成年男性。收集精液标本,采用计算机辅助精液分析系统(CASA)对精子参数进行分析。结果:高海拔组的精子密度、精子曲线运动速度(VCL)、直线运动速度(VSL)、平均路径速度(VAP)和直线性(LIN)分别为(51.12±14.61)×106/ml、(48.17±13.52)μm/s、(32.64±6.70)μm/s、(41.21±9.32)μm/s和(52.24±8.14)%,均明显低于对照组(P<0.01或P<0.05)。中海拔组的精子密度、精子活率、VSL、VCL、LIN、VAP和ALH等参数较对照组亦有不同程度的下降,但差异无显著性(P>0.05)。结论:随着海拔高度的增加,高原缺氧暴露对成年男性的精子参数的负面影响愈明显。     

The relationship between environmental exposure to phthalates and computer-aided sperm analysis motion parameters

The general population is exposed to phthalates through consumer products, diet, and medical devices. The present study explored whether phthalates, reproductive toxins in laboratory animals, were associated with altered sperm movement characteristics in men. Two-hundred twenty subjects provided a semen sample for computer-aided sperm analysis (CASA) and a urine sample for measurement of phthalate monoesters, monoethyl (MEP), monobenzyl (MBzP), mono-n-butyl (MBP), mono-2-ethylhexyl (MEHP), and monomethyl (MMP). Three CASA parameters, straight-line velocity (VSL), curvilinear velocity (VCL), and linearity (LIN), were used as measures of sperm progression, sperm vigor, and swimming pattern, respectively. There were suggestive dose-response relationships (shown as the predicted change in mean sperm motion parameter for the second and third tertiles compared with the first tertile; P value for trend) for MBzP with VSL (-2.36 microm/s, -2.81 microm/s; P =.09) and VCL (-1.67 microm/s, -2.45 microm/s; P =.4). There were suggestive negative associations between MBP and VSL (-3.07 microm/s, -2.87 microm/s; P =.08) and VCL (-3.25 microm/s, -3.46 microm/s; P =.2), and between MEHP with VSL (-1.09 microm/s, -2.73 microm/s; P =.1) and VCL (-0.29 microm/s, -2.93 microm/s; P =.3). In contrast to the other phthalates, MEP was positively associated with VSL and VCL but negatively associated with LIN. No consistent relationship was found for MMP and any sperm motion parameter. Although we did not find statistically significant associations, trends between CASA parameters, sperm velocity, and forward progression, and increased urinary levels of MBP, MBzP, and MEHP warrant further follow-up.

The effect of reactive oxygen species on equine sperm motility, viability, acrosomal integrity, mitochondrial membrane potential, and membrane lipid peroxidation

The objective of this study was to examine the influence of reactive oxygen species (ROS), generated through the use of the xanthine (X)-xanthine oxidase (XO) system, on equine sperm motility, viability, acrosomal integrity, mitochondrial membrane potential, and membrane lipid peroxidation. Equine spermatozoa were separated from seminal plasma on a discontinuous Percoll gradient, and spermatozoa were incubated with 0.6 mM X and 0.05 U/mL XO for 30 minutes. Catalase (150 U/mL), superoxide dismutase (SOD, 150 U/mL), or glutathione (GSH, 1.5 mM) were evaluated for their ability to preserve sperm function in the presence of the induced oxidative stress. At the end of the 30-minute incubation, sperm motility was determined by computer-assisted semen analysis. Viability and acrosomal integrity were determined by Hoechst-Pisum sativum staining, and mitochondrial membrane potential was determined by staining with JC-1. Incubation with the X-XO system led to a significant (P < .01) increase in hydrogen peroxide production and an associated decrease (P < .01) in motility parameters. Total motility was significantly (P < .01) lower in the presence of X-XO compared with the case of the control (29%+/-9% vs 73%+/-1%, respectively). Catalase, but not SOD, prevented a decline in motility secondary to oxidative stress (71%+/-4% vs 30%+/-3%, respectively). The addition of glutathione had an intermediate effect in preserving sperm motility at the end of the 30-minute incubation (53%+/-3%). No influence of X-XO could be determined on viability, acrosomal integrity, or mitochondrial membrane potential. In order to promote lipid peroxidation, samples were incubated with ferrous sulfate (0.64 mM) and sodium ascorbate (20 mM) for 2 hours after the X-XO incubation. No increase in membrane lipid peroxidation was detected. This study indicates that hydrogen peroxide is the major ROS responsible for damage to equine spermatozoa. The decrease in sperm motility associated with ROS occurs in the absence of any detectable decrease in viability, acrosomal integrity, or mitochondrial membrane potential or of any detectable increase in lipid peroxidation.     

Analysis of factors associated with multinucleate formation in human IVF

This study was carried out to analyse if some of the sperm parameters assessed by computer-aided sperm analysis (CASA) are associated with multinucleate formation in human in vitro fertilization (IVF). In the present study, 137 IVF-embryo transfer (ET) treatment cycles in which pronucleate formation could be observed were enrolled. Sperm parameters after swim-up were assessed using CASA and strict criteria. Thirty-two (2.3%) of 1368 oocytes fertilized were judged as multinucleate formation, which occurred in 25 of 137 IVF-ET treatment cycles, giving the incidence of 18.2%. The factors associated with multinucleate formation were analysed. There were significant differences of the numbers of oocytes collected (13.9 vs. 9.2; p=0.028), fertilization rate (88.8% vs. 71.9%; p=0.011), curvilinear velocity (VCL) (162.7 microm/sec vs. 149.1 microm/sec; p=0.034), average path velocity (VAP) (100.3 microm/sec vs. 93.1 microm/sec; p=0.016), and amplitude of lateral head displacement (ALH) (5.9 microm vs. 5.3 microm; p=0.046) between 25 cycles with multipronucleate formation and 112 cycles with two pronucleate formations. However, there were no significant differences of women's age or the number of sperm inseminated between the two groups. These findings suggest that prediction of multinucleate formation in human IVF might be possible in patients when the number of oocytes collected is higher and sperm motility parameters after swim-up are faster. However, prevention of multinucleate formation seems to be unnecessary because a higher successful IVF-ET outcome is expected as a result of the excellent fertilization rate in these patients.

Effects of sauna on sperm movement characteristics of normal men measured by computer-assisted sperm analysis

The effects of sauna exposure on sperm movement characteristics and other semen parameters were evaluated using computer-assisted sperm analysis (CASA). A significant ( p  < 0.01) decrease in average path velocity (VAP), curvilinear velocity (VCL) and amplitude of lateral head displacement (ALH) was found after exposure to sauna for 2 weeks. The altered parameters returned to their original values within 1 week after cessation of sauna exposure. Mean values for semen volume, sperm count, percentage motility, sperm morphology and sperm penetration assay (SPA) were not statistically different during and after sauna, when compared to the corresponding control values. The results suggest that increasing scrotal temperature by sauna causes a reversible decrease in sperm movement parameters.

Visco-elasticity of seminal fluid in relation to the epididymal and accessory sex gland function and its impact on sperm motility

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.     

Evaluation of effects of 1,3-dinitrobenzene on sperm motility of hamster using computer assisted semen analysis （CASA）

Aim: To evaluate the effects of 1,3-dinitrobenznene (mDNB) on sperm motility of hamster and to correlate the resuits with the fertility. Methods: Adult male hamsters were gavaged with one of the 3 dose regimes of mDNB (1.5 mg daily for 4 weeks, 1.5 mg one day a week for 4 weeks and 1.0 mg 3 days a week for 4 weeks). Computer assisted semen analysis (CASA) was used to analyse the sperm motility parameters, curvilinear velocity (VCL) and straight line velocity (VSL) of sperm in distal corpus epididymides and distal cauda epididymides. In vitro fertilisation was carried out only for l. 5 mg mDNB daily group to determine the sperm fertilising capacity. Results: There was a significant reduction in sperm velocity parameters at weeks 3 and 4 after treatment, which was correlated with a decline in sperm fertility. Conclusion: Sperm velocity parameters may be used to determine the effect of a toxic insult on the sperm function.
