The present work describes experiments undertaken to evaluate the usefulness of selected physicochemical indices of semen, cell membrane integrity and sperm chromatin structure for the assessment of b...
Analysis of sperm parameters is very important for predicting the outcome of assisted reproductive techniques and is necessary for determination of fertility potential of males tested for artificial i...
Data obtained by the sperm chromatin structure assay (SCSA) on spermatozoa from nine bulls were correlated with fertility, measured by heterospermic performance (-0.94, P less than 0.01) and by al...
Scrotal regions of mice were exposed to a 38.0, 40.0, or 42.0 degrees C (+/-0.1) H2O bath for 60 minutes to determine the effects of elevated temperatures on testicular cells and sperm chromatin str...
Mouse epididymal sperm incubated in Tyrode's T6 fertilization media were analyzed over time for chromosome damage by two methods. First, cytogenetic analysis was done on paternal pronuclei metapha...
Tests were carried out on sperm from 40 fertile and infertile men to evaluate 2 DNA in situ denaturation methods using acridine orange (AO; the modified Rigler-Roschlau method and the Tejada method), ...
Semen samples from a fertile patient presenting with influenza and a 1-day fever of 39.9 degrees C were obtained and analyzed at 18-66 days postfever (dpf) for sperm nuclear proteins, DNA stainabi...
Koala (Phascolarctos cinereus) sperm nuclei show a tendency to swell after cryopreservation, but it is uncertain whether this phenomenon is associated with DNA fragmentation. In this study, we va...
The incidence of testicular cancer has increased dramatically over the past 50 years. Advances in treatment, which include the coadministration of bleomycin, etoposide, and cis-platinum (BEP),...
Previous studies suggest that sperm DNA fragmentation may be associated with aneuploidy. However, currently available tests have not made it possible to simultaneously perform DNA fragmentatio...
The effect of seasonality (temperate environment, Spain) on the chromatin status of ovine (Churra breed), Iberian red deer, and brown bear spermatozoa was studied. This work aims to improve genet...
The frequency of sperm cells with fragmented DNA was studied in a group of 18 infertile patients with varicocele and compared with those obtained in a group of 51 normozoospermic patients, 103 patie...
Oxidative stress is detrimental to sperm function and a significant factor in the etiology of male infertility. This report examines the association between dietary and supplementary intake of the...
During the past decade, the sperm chromatin structure assay (SCSA) has become an important tool for assessing semen quality in the human andrology laboratory. The SCSA uses the metachromatic propert...
We hypothesized that cryopreservation and incubation in conditions that mimic the female genital tract following insemination increases the susceptibility of ram sperm DNA to denaturation. Ram spe...
