TLDR
The results indicate that SQA IIC might be used as an initial screening test for the evaluation of sperm morphology, however, sperm morphological assessment by the strict criteria should be performed in order to make decisions in planning strategies for the treatment of infertile couples.Abstract:
The aim of the present study is to investigate the accuracy of the normal sperm morphology value by Sperm Quality Analyzer IIC (SQA IIC), which was developed to provide a rapid and low-cost quantitative evaluation of semen quality. Normal sperm morphology was assessed using SQA IIC in comparison with that by the strict criteria in 62 semen samples. Normal sperm morphology value by SQA IIC was based on the studies of three traditional sperm parameters from over 4000 fresh, untreated semen samples, while the strict criteria was based on the method by Kruger et al. The mean +/- SD of percent normal morphology by SQA IIC and the strict criteria were 37.6 +/- 10.9% (range 15-52) and 19.9 +/- 8.2 (range 1-34), respectively. There was a significant correlation of the sperm morphology assessment between the two methods (r=0.454, p 30% normal morphology by SQA IIC, the positive predictive value and the negative predictive value of the 'normal' strict criteria were 79.6% (39/49) and 46.2% (6/13), respectively. These results indicate that SQA IIC might be used as an initial screening test for the evaluation of sperm morphology. However, sperm morphological assessment by the strict criteria should be performed in order to make decisions in planning strategies for the treatment of infertile couples.read more

Levels of oxidative stress biomarkers in seminal plasma and their relationship with seminal parameters
TL;DR: Decreasing seminal plasma antioxidants levels, especially catalase and TAC, could have significant role in etiology of impaired sperm function and measurement of 8-Isoprostane may be used as a specific biomarker for assessing oxidative stress on sperm.

Fatty acid composition of human spermatozoa and seminal plasma levels of oxidative stress biomarkers in subfertile males
TL;DR: Spermatozoa from pathological samples may have higher levels of polyunsaturated fatty acids, especially docosahexaenoic acid (DHA), than spermatozoA from normozoospermic men, therefore, damage induced by lipid peroxidation would be higher in spermatozosa from pathology samples than those from normal men.

Correlation between Sperm Quality Parameters and Seminal Plasma Antioxidants Status
TL;DR: Cutting seminal plasma antioxidant status especially catalase activity and TAC may have significant role in etiology of sperm abnormality and showed a positively significant correlation with progressively motile sperms and normal sperm morphology.

Relationship between chromatin condensation, DNA integrity and quality of ejaculated spermatozoa from infertile men.
TL;DR: It is demonstrated that men with morphologically normal spermatozoa of <30% have greater degree of protamine deficiency and DNA damage than men with morphology of >30% and evaluation of chromatin integrity appears to be a useful tool for assessing male fertility.

TL;DR: The suitability of the proposed method was confirmed using spermatozoa prepared from mice treated with the reproductive toxin diethylstilbestrol (DES), and measurement of these sperm parameters using the two devices was simple, rapid, inexpensive, and reproducible.

TL;DR: The relationship of conventional semen parameters and the limits of these parameters for fertilization in vitro were analyzed from data over a 3-year period (1980 to 1982) as mentioned in this paper, where sperm motility was the single most important parameter determining the fertilization rate.

TL;DR: It was found that a low mean value of the amplitude of lateral sperm head displacement and an increased percentage of abnormal acrosomes were related to in-vitro fertilization failure.
