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.

[Sperm quality and selection].
Journal de gynecologie, obstetrique et biologie de la reproduction, 2008Selection of a live and morphologically normal spermatozoa is a fundamental stage in ICSI success because of its potential effects on early and late embryo development. In addition to the routine tests such as the spermogram and the spermocytogram, a number of tests have been developed for this purpose : the hyaluronic acid test, which measures the ...
