The hypo‐osmotic (HOS) test has been used in other species as an indicator of the fertilising
capacity of spermatozoa. The aims of this study were to assess the response of domestic cat …

Two methods of measuring human sperm viability, the stain exclusion assay and the
hypoosmotic swelling (HOS) test, were evaluated. Human sperm were pretreated with 2.0 …

The conventional seminal parameters like sperm density, motility, morphology, etc. are not
perfect indicators of seminal functional quality. Hence, Seminal Hyaluronidase Activity (SHA) …

Purpose To determine if males with low hypoosmotic swelling (HOS) test scores may have
normal vitality tests. Methods Retrospective nine-year review of initial semen analyses …

Objective To determine the distribution of sperm abnormalities in a population of suspected
infertile men presenting for the initial investigation of male factor infertility. Study design …

The hypoosmotic swelling test (HOST) has been proved to be a good tool for evaluating the
membrane integrity of spermatozoa of various domestic animals including cattle, horses …

Twenty ejaculates from 5 adult dogs were collected by digital manipulation in order to study
the functional capacity of spermatozoal membranes in fresh and frozen/thawed semen. The …

Objective: Hypo-osmotic swelling test (HOST) has been shown to be an effective method for
the selection of live sperm. On-going pregnancies were obtained by using HOST-selected …

Contents Routine semen evaluation includes volume, motility, vital staining for live‐dead
ratio and pathomorphology including Spermac® staining for evaluation of the acrosome. In …

BACKGROUND: Various methods for the selection of viable sperm from among immotile
testicular spermatozoa for use in ICSI have been described in non-randomized studies. We …
