Computer-assisted sperm analysis of fresh and frozen-thawed bovine sperm requires proper handling and preparation, and the type of slide used in the assessment is critical if the resultant data are to be useful quality control measurements. In the present study, 4 different slide viewing chambers, a Makler chamber, a clean slide-coverslip, or a 2- or 4-cell chamber Leja slide, were compared wit...
Sperm chromatin/DNA integrity is essential for the accurate transmission of paternal genetic information, and normal sperm chromatin structure is important for sperm fertilizing ability. The routine examination of semen, which includes sperm concentration, motility and morphology, does not identify defects in sperm chromatin structure. The origin of sperm DNA damage and a variety of methods for...
The objective of the present study was to identify sperm abnormalities in young male patients with juvenile dermatomyositis (JDM). In 2005, 18 male JDM patients, diagnosed according to the criteria of Bohan and Peter, were followed at the Pediatric Rheumatology Unit and Rheumatology Division, of our Institution. Of the 18 males, 11 were pre-pubertal and 7 were post-pubertal. Two of 7 post-puber...
Motile porcine sperms adhere to hydrophilic materials such as glass and plastics. The adsorption of sperms to a hydrophobic poly(dimethylsiloxane) (PDMS) membrane is less compared with that to glass. We investigated the linear velocity (LV) and amplitude of lateral head displacement (ALHD) of motile porcine sperm on glass and PDMS preparations using computer-assisted sperm analysis (CASA). Sign...
In this study, sperm characteristics (motility parameters and ionic composition of seminal plasma) and effect of ions on motility (duration of motility of sperm and percentage of motile spermatozoa) and fertilization capacity (fertilization rate, hatching rate, survival rate and larvae length) were investigated in Ctenopharyngdon idella. The longest duration of motility obtained in solution con...

Vitamin D levels have been linked to various health outcomes including reproductive disorders. The purpose of this study was to explore the association between serum vitamin D level (25-hydroxy-vitamin D, or 25OHD) and semen and hormonal parameters. This is a cross-sectional study that included 170 healthy men recruited for the study of spermatogenesis from the general population. Men completed...
OBJECTIVE Study associations between three measures of alcohol consumption (recent, typical/habitual, binging), semen quality and serum reproductive hormones. DESIGN Cross-sectional population based study. SETTING AND PARTICIPANTS 1221 young Danish men, aged 18-28 years were recruited when they attended a compulsory medical examination to determine their fitness for military service from 20...
This study was conducted to determine a possible relationship between regular cell phone use and different human semen attributes. The history-taking of men in our university clinic was supplemented with questions concerning cell phone use habits, including possession, daily standby position and daily transmission times. Semen analyses were performed by conventional methods. Statistics were cal...
BACKGROUND Intrauterine insemination (IUI) could become preferred to more invasive and expensive techniques of assisted reproduction therapy (ART) and should be offered as the first choice in cases with no female factors and mild male factor subfertility. However, developing countries and especially their rural areas often lack the necessary equipment and laboratory facilities. OBJECTIVE To d...
