Computer assisted semen analyzers in andrology research and veterinary practice
TL;DR: Although some interesting results, mainly in humans, have already been obtained, many questions remain, which have to be answered to allow for further development of this technology in veterinary medicine, clinical fertility settings, physiological and toxicology research activities.

Environmental endocrine modulators and human health: an assessment of the biological evidence.
Robert Golden,Kenneth L. Noller,Linda Titus-Ernstoff,Raymond H. Kaufman,Robert Mittendorf,Robert Stillman,Elizabeth A. Reese +6 more
TL;DR: Biological plausibility alone is an insufficient basis for concluding that environmental endocrine modulators have adversely affected humans, and it appears unlikely that in utero exposure to usual levels of environmental estrogenic substances, from whatever source, would be sufficient to produce many of the effects.

Extracellular matrix composition and hypoxia regulate the expression of HLA-G and integrins in a human trophoblast cell line.

TL;DR: HTR-8/SVneo cells retain several important characteristics associated with primary cultures of first-trimester human cytotrophoblast cells, including their altered behavior in response to a changing maternal environment.
Journal ArticleDOI
Prognostic significance of computerized motility analysis for in vivo fertility
TL;DR: The measurement of quantitative motility and sperm number using a HTM Analyser is of clinical value and a number of variables were significantly related to time to conception.

Evidence for regional differences of semen quality among fertile French men. Fédération Francaise des Centres d'Etude et de Conservation des Oeufs et du Sperme humains.
Jacques Auger,Pierre Jouannet +1 more
TL;DR: This is the first study providing evidence for regional differences in the human semen quality, with significant differences found between centres for seminal volume, sperm concentration, total number of spermatozoa in the ejaculate and percentage of motile spermutozoa.

Computerized semen analysis: objective measurement of semen characteristics is biased by subjective parameter setting.
TL;DR: It is concluded that results of automated semen analysis may not be comparable among different laboratories unless identical parameter settings are used.

TL;DR: Semen samples from 77 men were used to estimate the accuracy and precision of measurements of sperm density, percent motility, and motion characteristics using a new, fully automated, computer-assisted semen analyzer (CASA).

A new chamber for rapid sperm count and motility estimation.
TL;DR: Easy performance, rapid sperm counts, and improvement of motility estimation make this chamber a useful tool where sperm analysis is carried out.
