Quantitative assessment of nocturnal penile tumescence and rigidity in normal men using a home monitor
Quantitative assessment nocturnal penile tumescence rigidity normal men
2009/2/23
Current methods now permit the measurement of nocturnal penile tumescence and rigidity (NPTR) in men with erectile dysfunction. But the relationship of rigidity to tumescence and the changes in rigidi...
Human sperm mitochondrial function related to motility：a flow and image cytometric assessment
Human sperm mitochondrial function motility cytometric assessment
2009/2/23
Current evaluation of male fertility, routinely estimated by sperm count, motility, and morphology, provides only crude information about the fertility state of individuals. Both flow and image cyto...
Morphometric analysis of spermatozoa in the assessment of human male fertility
human spermatozoa morphometry fertility
2009/2/23
A videomicrographic system was developed for measurement of morphometric parameters of human spermatozoa. Contours of the images of spermatozoa on a video monitor are digitized by manually tracing t...
Sperm morphology assessment as an indicator of human fertilizing capacity
Sperm morphology assessment indicator human fertilizing capacity
2009/2/19
Semen samples from 95 men were examined by routine semen analysis and specific histologic staining for sperm morphology. The men were classified into fertile and infertile groups on the basis of cli...
Continuous assessment of human spermatozoa viability during cryopreservation
Sperm cryomicroscopy fluorescent viability probes
2009/2/17
Cryomicroscopy has enabled direct observation of freezing and thawing of human spermatozoa. When used with a fluorescent viability kit, sperm membrane damage was not apparent down to temperatures of...
Analysis of the effect of nitric oxide synthase inhibition on mouse sperm employing a modified staining method for assessment of the acrosome reaction
Nitric oxide synthase acrosome reaction
2009/2/17
A commercially available staining kit (Spermac) was combined with swelling in a hypoosmotic medium (HOS) for simultaneous assessment of viability and acrosome reaction in mouse spermatozoa. We com...
Choice of operating conditions to minimize sperm subpopulation sampling bias in the assessment of boar semen by computer-assisted semen analysis
CASA computer semen analysis tracking semen
2009/2/16
The performance of a computer-assisted semen analysis system was evaluated for use with washed boar spermatozoa. Accuracy was tested using a computer graphics-generated series of spots moving along ...
Synchronous assessment of sperm motility and fertilizing ability in the hamster following treatment with alpha-chlorohydrin
Synchronous assessment sperm motility fertilizing ability
2009/2/13
To investigate the relationship between sperm motion parameters and fertilizing ability, a model was developed to assess both of these endpoints synchronously using a toxicant that inhibits sperm mo...
Dual DNA staining assessment of bovine sperm viability using SYBR-14 and propidium iodide
Sperm fluorescence SYBR-14 flow cytometry vital staining cryopreservation
2009/2/13
A new membrane-permeant DNA stain, SYBR-14, was used in combination with propidium iodide (PI) to estimate the proportion of living sperm in bovine semen. The SYBR-14 stained living sperm while PI...
Assessment of the hypothalamic-pituitary-testicular function in male patients with Wilson's disease
Liver disease gonadotropins gonadotropinreleasing
2009/2/7
Sixteen male patients with Wilson's disease were studied to detect potential endocrine dysfunctions. There was no clinical evidence of feminization in any of the patients, and the patient group span...

Testosterone spermatogenesis ABP
2008/12/29
Previous studies of the rat have shown that testosterone concentrations within the interstitial and seminiferous tubularfluids of the testes are significantly higher than normal serum levels, and furt...
Assessment of the acrosomal status of ram spermatozoa by RCA lectin-binding and partition in an aqueous two-phase system
acrosomal status ram spermatozoa RCA lectin-binding partition aqueous two-phase system
2008/12/25
The acrosome reaction is an important marker for sperm function. Because different laboratory techniques may be used to detect this exocytotic process, the objective of this study was to investiga...
