Summary of "Semen parameters and testicular dimensions in small breed dogs below ten-kilogram bodyweight."

Because of few available data on semen parameters in small breed dogs, the study aimed to analyse semen and measure testes of dogs < 10.0 kg bodyweight. Semen was collected from 41 fertile stud dogs which were divided based on bodyweight: group 1 < 5.0 kg, and group 2 between 5.1 and 10.0 kg. Median values for ejaculate volume (group 1: x ̃ 1.2 mL; group 2: x ̃ 2.2 mL), total sperm output (group 1: x ̃ 110.7 x 106; group 2: x ̃ 215.1 x 106) and testicular volume (group 1: left testicle x ̃ 2.8 mL, right testicle x ̃ 2.7 mL ; group 2: left testicle x ̃ 5.5 mL, right testicle x ̃ 5.0 mL) were lower in group 1 compared to dogs of group 2 (P = 0.001; P = 0.001; both testes: P < 0.001). There was no difference in sperm concentration (P = 0.985). Based on these results introduction of an additional weight group to the commonly used reference values is recommended, since values for ejaculate volume, total sperm output and testicular dimensions for dogs < 5.0 kg bodyweight differed significantly from values of dogs with a bodyweight from 5.1 to 10.0 kg.

Medical and Biotech [MESH] Definitions

Animals which have become adapted through breeding in captivity to a life intimately associated with man. They include animals domesticated by man to live and breed in a tame condition on farms or ranches (e.g., horses, cattle, sheep) and those raised or kept for pleasure and companionship (e.g., dogs, cats, horses).

The quality of SEMEN, an indicator of male fertility, can be determined by semen volume, pH, sperm concentration (SPERM COUNT), total sperm number, sperm viability, sperm vigor (SPERM MOTILITY), normal sperm morphology, ACROSOME integrity, and the concentration of WHITE BLOOD CELLS.

Scattering of a beam of electromagnetic or acoustic RADIATION, or particles, at small angles by particles or cavities whose dimensions are many times as large as the wavelength of the radiation or the de Broglie wavelength of the scattered particles. Also know as low angle scattering. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed) Small angle scattering (SAS) techniques, small angle neutron (SANS), X-ray (SAXS), and light (SALS, or just LS) scattering, are used to characterize objects on a nanoscale.

A condition characterized by the complete absence of SEMEN. This disorder should be differentiated from AZOOSPERMIA, absence of sperm in the semen.

Small holes of nanometer dimensions in a membrane, that can be used as single molecule detectors. The pores can be biological or synthetic.
