Age Dependency of Spermatogenesis Efficiency in Cats

Age dependence of murine spermatogenesis.

The dependence of spermatogenesis function on murine age shall be investigated. Thus, testicular samples of at least 10 NMRI mice per group aged 0 to 26 months are analysed by flow cytometry after staining the DNA with DAPI. The aim of this study is to be able to account for the influence of age on mice. There are no changes in spermatogenesis in mice aged 11 weeks up to 16 months with respect ...

Efficiency of spermatogenesis: a comparative approach.

Efficiency of spermatogenesis is the estimated number of spermatozoa produced per day per gram of testicular parenchyma. Spermatogenesis is the process of cell division and cell differentiation by which spermatozoa are produced in testes. Efficiency of spermatogenesis is influenced by species differences in the numerical density of germ cell nuclei and in the life span of these cells. Activitie...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Early-age desexing of cats and dogs

Early-age desexing (EAD) is the desexing of cats and dogs at an earlier age than when the procedure is traditionally carried out. The traditional desexing age for dogs and cats is generally around 51⁄2 to 6 months of age (sometimes from 5 months of age), although this can vary between individual cats and dogs and according to breed. In contrast, EAD is defined as desexing between 6–16 weeks of ...
