Association between obesity and sperm quality
Andrologia, 2017There is awareness of likelihood of abnormal spermatozoa in obese men; however, results from previous studies are inconclusive. Advances in computer-aided sperm analysis (CASA) enable precise evaluation of sperm quality and include assessment of several parameters. We studied a retrospective cohort of 1285 men with CASA data from our infertility clinic

Sperm quality during extra‐gonadal sperm reserve depletion in stallions
Reproduction in Domestic Animals, 2018ContentsTo estimate when, during stallions’ extra‐gonadal reserves (EGR) depletion period, sperm quality would reach its highest quality, six light breed sexually rested stallions were collected daily for 7 days to deplete EGR. On collection days 1, 3, 5, and 7, sperm output, total (TM) and progressive (PM) motility, morphology, and plasma membrane ...

Making sperm: design, quality control and sperm competition.
Society of Reproduction and Fertility supplement, 2007Spermatozoa vary remarkably in design at several different levels: phyla, orders, families, species, individuals, within individuals and within ejaculates of the same individual. Three factors are thought to account for some of this variation: (i) fertilisation mode; (ii) phylogeny, and (iii) postcopulatory sexual selection (i.e.

[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 ...

Sperm Production and Variance in Sperm Quality
2009An unusually high level of inter- and intraspecific variability in spermatozoa has been well documented. However, recent evidence indicates that the level of variation within spermatozoa differs markedly across taxa. In particular, it appears that the variability in spermatozoa tends to decrease across species as the risk of sperm competition increases.
