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 …

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 …

In summary, the hypoosmotic viability parameter was significantly correlated with the
outcome of the thawed sperm motility. The prefreeze supravital staining for sperm viability …

Objective:[1] To examine the relationship between sperm membrane integrity and motion
parameters before and after cryopreservation;[2] to determine the capacity of the membrane …

The hypoosmotic swelling test is a simple laboratory test to evaluate the functional integrity
of the membrane of human spermatozoa. This test was performed on 83 samples of human …

Many centers have been disappointed with the pregnancy rate following the insemination of
cryopreserved-thawed sperm, despite the maintenance of an adequate motile density. The …

Abstract Normozoospermic semen samples (n= 82) were examined to investigate whether
the degree of sperm tail swelling in hypo-osmotic medium (fructose and sodium citrate; 150 …

In this study, frozen semen samples from 3 bulls were thawed at 37, 40 and 70° C for 20, 15
and 5 seconds, respectively. Sperm membrane integrity and motility were analysed using …

Human sperm viability is essential for successful fertilization. Eosin Y is the usually accepted
method for sperm viability assessment, though the hypoosmotic swelling test has been …

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 …
