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 ...

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.

Use of the Sperm Quality Analyzer (SQA II‐C) for the Assessment of Dog Sperm Quality
Reproduction in Domestic Animals, 2002ContentsIn the present study, an automated system for sperm analysis, the Sperm Quality Analyzer (SQA II‐C), was tested as a potential tool for the assessment of dog sperm quality. In the first experiment the device displayed a good repeatability of measurements for semen of medium and high quality, as evidenced by a low coefficient of variance (CV; 0 ...

Sperm nuclear protamines: A checkpoint to control sperm chromatin quality
Anatomia, Histologia, Embryologia, 2018AbstractProtamines are nuclear proteins which are specifically expressed in haploid male germ cells. Their replacement of histones and binding to DNA is followed by chromatin hypercondensation that protects DNA from negative influences by environmental factors. Mammalian sperm contain two types of protamines: PRM1 and PRM2.

Validation of the Sperm Quality Analyzer (SQA) for dog sperm analysis
Theriogenology, 2001In the present study, a simple and inexpensive unit (the Sperm Quality Analyzer-SQA), was evaluated for dog sperm analysis. Our objective was to propose a cheap, accurate and convenient device to be used in veterinary practices involved with dog fertility assessment and artificial insemination.

Advanced methods for evaluation of sperm quality
Andrologia, 2009Routine semen analysis includes measurements of sperm concentration, motility, and morphology. In our study, three additional tests were evaluated in relation to fertilization rate in an in vitro fertilization program: the freezing and hypo-osmotic swelling tests that evaluate the functional integrity and stability of the sperm membrane under extreme ...
