Background The hypoosmotic swelling test (HOST) was recommended as a predictive test
for in vitro fertilization (IVF) outcome. These results, however, were controversial and the …

Objective To determine whether the hypo-osmotic swelling test can assess viability of frozen
spermatozoa. Design Fresh semen specimens were divided into two aliquots: one was not …

Objective To determine correlation between hypoosmotic swelling (HOS) test on post-swim-
up sperm and results of IVF. Setting University clinic IVF program. Patients and interventions …

The ability of the hypoosmotic sperm swelling (HOS) test to identify nonfertilizing sperm
samples in a group of 50 couples undergoing in vitro fertilization (IVF) was investigated. The …

The hypoosmotic swelling test is a simple laboratory test to measure the functional integrity
of the human sperm membrane. Its in-vivo and in-vitro applicability needs to be evaluated …

Human ejaculates (n= 83) were analyzed for standard sperm parameters (concentration,
motility, and morphology), as well as for the ability of the spermatozoa to react (swell) in a …

Cryopreservation/thawing of sperm leads to decreased motile density. Most donor programs
select for cryopreservation a male with a high initial motile density and if the post-thaw …

The ability of sperm to swell in hypo‐osmotic conditions was examined in 211 semen
samples from the partners of patients about to undergo oocyte retrieval for in‐vitro …

The parameter of sperm viability in hypoosmotic solution (VHOS) provides information
concerning the membrane Integrity of the sperm head. The objective of this study was to …

Multivariate discriminant analysis was used to evaluate the usefulness of routine semen
parameters and the hypo‐osmotic swelling test (HOST) as predictors of the in‐vitro fertilizing …
