Evaluating the long-term performance and morphometry of common carp offspring arisen from cryopreserved sperm of a large-scale

Aquaculture Reports
Sperm cryopreservation represents a valuable tool in aquaculture for resource management, breeding, and preservation. This study explores the potential of cryopreservation in common carp breeding by comparing the performance and morphometry of progeny ...

The legacy of sperm banking: how fertility monitoring and disposal of sperm are linked with views of cancer treatment [PDF]

, 2011
Background: sperm banking is recommended for all men before cancer treatment, which carries a risk of long-term gonadal damage. However, relatively few men take up the offer.

EFFECT OF SPERM CONCENTRATION ON EJACULATE FOR MORPHOMETRIC TRAITS OF SPERMATOZOAS OF THE PIETRAIN BREED BOARS [PDF]

Journal of Central European Agriculture, 2010
An attempt to evaluate the effect of spermatozoa concentration in one ejaculate on their measurements, shape, frequency of occurrence of morphological abnormalities in spermatozoa and physical traits of boar ejaculates in Pietrain breed was made.

Sperm morphological and morphometric evaluation in captive collared peccaries (Pecari tajacu)

Pesquisa Veterinária Brasileira, 2013
The aim of this study was to compare different staining methods for the evaluation of sperm morphology by light microscopy and also to describe the morphometry of the entire sperm in collared peccaries (Pecari tajacu). Semen from 10 males was obtained by

Assessment of Sperm Morphometry in Evaluating Male Infertility

International Journal of Biomedicine
Background: Infertility is a complex issue affecting 15% of couples of reproductive age, with men accounting for 40%-50% of infertility cases. Semen analysis comprises various descriptive measures of sperm and seminal fluid to determine semen quality. Transforming qualitative descriptions of sperm deformities and shape changes into quantitative terms ...

Low‐mobility sperm phenotype in the domestic turkey: Impact on sperm morphometry and early embryonic death

Reproduction in Domestic Animals, 2019
ContentsThe sperm mobility assay measures the ability of sperm to swim through a dense layer of Accudenz®, and the sperm mobility phenotype has been shown to predict fertility and other sperm performance traits in roosters and turkeys. In this study, we examined turkey sperm morphometry and rates of early embryonic death associated with high‐ and low ...

A comparative study of the morphometry of sperm head components in cattle, sheep, and pigs with a computer-assisted fluorescence method

Asian Journal of Andrology, 2016
The aim of this study was to compare the sperm nuclear and acrosomal morphometry of three species of domestic artiodactyls; cattle (Bos taurus), sheep (Ovis aries), and pigs (Sus scrofa). Semen smears of twenty ejaculates from each species were fixed and

Studies on the sperm reservoir of the pig oviduct [PDF]

, 2003
During sperm transport in the female pig a proportion of spermatozoa are arrested, often for 24 h or more, in a particular segment of the utero-tubal junction (UTJ) and the adjacent tubal isthmus, where a sperm reservoir (SR) is built up.
