Sperm nuclear protamines: A checkpoint to control sperm chromatin quality

Anatomia, Histologia, Embryologia, 2018
AbstractProtamines 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, 2001
In 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, 2009
Routine 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 ...

[Sperm quality and selection].

Journal de gynecologie, obstetrique et biologie de la reproduction, 2008
Selection 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 ...
