Relationship between the clinically diagnosed male infertility and individual, conventional and flow cytometric SPTRX3 parameters reflective of sperm quality.

An odds ratio smaller than 1 indicates that the parameter is negatively associated with the odds of being diagnosed with male infertility. A larger than 1 odds ratio indicates a positive relationship between the parameter and the clinical diagnosis of male infertility. An odds ratio larger than 1, e.g. 1.12 is interpreted as “the odds of being diagnosed with male infertility increase by 12% for every unit of increase in the parameter measurements.” An odds ratio smaller than 1, e.g., 0.014, is interpreted as “the odds of being diagnosed with male infertility decrease by 98.6% for every unit of increase in the measured parameter.” Abbreviations: C = sperm count; V = semen volume; M = total motility; PR = progressive motility; NX = morphology/% normal spermatozoa; NEC = percent of necrotic spermatozoa assessed by Williams test.
