Ninety semen samples from male patients were studied. They were classified into 4 different
groups; normospermic fertile, oligospermia, asthenospermia, and oligoasthenospermia. In …

Semen samples of 209 males of infertile couples were evaluated by the sperm hypoosmotic
swelling (HS) test, the in vitro human sperm zona-free hamster ovum penetration assay …

The hypo‐osmotic swelling (HOS) test has been proposed as a useful assay in the
diagnosis of the infertile male. A good correlation between the HOS test and the sperm …

The hypo‐osmotic swelling (HOS) test has been proposed as a useful assay for evaluation
of the functional competence of the human sperm membranes. To assess this further, the …

The simple hypo-osmotic swelling test (HOS) has been proposed as a replacement for the
labor-intensive sperm penetration assay (SPA), but its reliability is still controversial. To …

The hypoosmotic swelling test is a simple test for measuring the functional competence of
the human sperm membrane. Fifty-four patients with idiopathic infertility were assessed by …

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 …

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 …

The correlation between the hypo‐osmotic swelling test, the modified Eliasson score for
human semen analysis and the hamster egg penetration assay was examined. The results …

We examined spermatozoa from 135 male patients consulting for infertility to evaluate the
usefulness of the hypo-osmotic swelling (HOS) test of sperm fertility for the swim-up washing …
