Cigarette smoking and sperm quality*
Andrologia, 2009The effect of cigarette smoking on conventional semen parameters (volume, total sperm count, sperm count/ml, total motility, progressive motility, morphology) was studied retrospectively in 90 healthy patients (50 non-smokers, 40 smokers) of our infertility clinic.

Stability of sperm characteristics in men with disturbances in sperm quality
International Journal of Andrology, 1989SummarySixty‐one men referred to our laboratory for semen analysis, and subsequently judged to exhibit some form of sperm pathology, were asked to return for a second analysis, not less than 2 months after the first, in order to assess the stability of the pathological changes observed.

Evaluation of sperm fertilizing ability using the Sperm Quality Analyzer [PDF]
Journal of Developmental and Physical Disabilities, 1997 The Sperm Quality Analyzer is an inexpensive device which provides a quantitative estimation of sperm motility. To evaluate the fertilizing ability of human spermatozoa using a Sperm Quality Analyzer, correlations amongst the sperm motility index, the sperm penetration index (as assessed using the sperm penetration assay; SPA), and the fertilization ...

Sperm telomere length as a parameter of sperm quality in normozoospermic men [PDF]
Human Reproduction, 2016 Could sperm telomere length (STL) represent a novel parameter and biomarker of sperm quality?STL is associated with standard semen quality parameters and, more importantly, it is significantly associated with levels of DNA fragmentation and sperm protamination.Telomeres are fundamental for genome integrity.

Sperm hyperactivation as quality control for sperm penetration assay
Urology, 1992The sperm penetration assay (SPA) is subject to considerable variation, and controls are needed to verify the accuracy of the results. It is proposed that sperm hyperactivation (HA) can serve as a quality control check for the SPA. The objective was to determine if there was an association between the SPA outcome and sperm HA measured at various times ...

Outdoor air pollution and sperm quality [PDF]
Fertility and Sterility, 2016 Exposure to air pollution has been clearly associated with a range of adverse health effects, including reproductive toxicity, but its effects on male semen quality are still unclear. We performed a systematic review (up to June 2016) to assess the impact of air pollutants on sperm quality.

Utilisation of a sperm quality analyser to evaluate sperm quantity and quality of turkey breeders
British Poultry Science, 20021. A relatively new instrument known as a Sperm Quality Analyzer (SQA) offers a rapid assessment of sperm quality and quantity by providing a sperm quality index (SQI). The SQA measures a combination of the intensity of sperm activity and motile concentration by determining the number and amplitude of sperm movements per second in a capillary tube as ...
