Morphometric differences in sperm head dimensions of fertile and subfertile stallions.

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.

Objectively measured sperm motility and sperm head morphometry in boars (Sus scrofa): relation to fertility and seminal plasma growth factors.
Miyako Hirai,Auke Boersma,Andreas Hoeflich,Eckhard Wolf,Jürgen Föll,Roland Aumüller,J. Braun +6 more
TL;DR: The nonreturn rate (NRR) and the number of live-born piglets were compatible with the requirements of artificial insemination for all boars included in this study and concentrations of IGF-I and IGF-II in seminal plasma were determined.

Functional significance of the sperm head morphometric size and shape for determining freezability in iberian red deer (Cervus elaphus hispanicus) epididymal sperm samples.
Milagros C. Esteso,Ana J. Soler,María Rocío Fernández-Santos,Armando Quintero-Moreno,José Julián Garde,José Julián Garde +5 more
TL;DR: Sperm quality at thawing for all sperm parameters evaluated was significantly higher for "good" freezers than for the "bad" ones, and it is possible that sperm head area and shape influence total sperm volume, thus causing differences in heat exchange as well as in movements of water, ions, and cryoprotectants and, in turn, on sperm freezability.

Computer assisted sperm morphometry in mammals: a review.
TL;DR: This review focuses on a complete description of the CASMA technique, including recent developments, factors of variation, results in the different species and possible applications, and how it may provide relevant information in studies focused on evolutionary biology, sperm formation, sperm quality assessment.

TL;DR: A comparison of human sperm heads in shallow wet preparations and in dried, stained preparations indicated that the latter were smaller in length, width, projected area, and circumference, but that the ratio length/width was not different, and it was the per-ejaculate variability of this parameter that maximized the difference.

Determination of the relationship between sperm morphologic classifications and fertility in stallions: 66 cases (1987-1988).
TL;DR: It appears that in stallions, a large percentage of ejaculated sperm with major defects or other defects in combination with major defect is associated with a larger reduction in fertility than is associatedwith other defects.

Quantification and classification of human sperm morphology by computer-assisted image analysis
TL;DR: The results demonstrate the ability of automated image analysis to classify individual sperm into clinically familiar shape categories and most of the misclassification errors occurred among closely related classes.

TL;DR: The CFH instrument exceeds the accuracy and precision of most manual approaches and with improvements in sperm recognition and type classification algorithms, it could significantly improve the reliability of morphology assays in clinical and research laboratories.
