background: pentoxifylline (px) is a methyl xanthine derivative that influences the sperm motion characteristics and l-carnitine (l-c) is an amino acid that is naturally produced in the body. in general, separate administration of px and l-c has been reported to be effective on preserving sperm motility in vitro, and also when is consumed orally by the idiopathic oligoasthenoteratozoospermia (i...

The aim of the present study was to compare assessments of sperm concentration and sperm motility analysed by conventional semen analysis with those obtained by computer-assisted semen analysis (CASA) (Copenhagen Rigshospitalet Image House Sperm Motility Analysis System (CRISMAS) 4.6 software) using semen samples from 166 young Danish men. The CRISMAS software identifies sperm concentration and...

Although patients with functional dyspepsia complain of epigastric symptoms, the relation between these symptoms and gastric motility remains controversial. There are few reports on the clinical course of functional dyspepsia, including changes in gastric motility, observed over a considerably long period. We conducted a study to examine association between changes in symptoms and changes in ul...

Background: Many studies are being conducted to improve the quality of bull sperm in storage conditions. It seems that increasing sperm membrane unsaturated fatty acids can enhance sperm quality. This study was aimed to investigate the effects of combination of omega- 3, 6, 9 fatty acids on characteristics of bovine chilled semen. Materials and Methods: Different levels of oil containing omega-...

Antioxidant properties of ghrelin have been demonstrated in recent studies. In the present study, theeffects of chronic administration of ghrelin on the motility and plasma membrane integrity of rat spermatozoa during incubation at 37ºC were investigated. Thirty 45-day-old male Wistar rats were divided into control and treatment groups. Rats in the treatment group were daily injected subcutaneo...

Wild-type and selected mutants of Paramecium tetraurelia were subjected to detailed analysis of the trichocyst phenotype. The characteristics of morphology, saltatory motility, and cortical insertion of trichocysts were found to be genetically distinguishable. In mutants with defective trichocyst saltatory motility, other intracellular motility systems (i.e. mitochondrial saltatory motility, an...

Motility is one of the most important characteristics associated with the fertilising ability of spermatozoa indicating their viability and structural integrity. Therefore, the examination of motility constitutes an integral part of semen analysis. Computer-assisted semen analysis (CASA) allows an accurate and objective assessment of different sperm motion characteristics with high repeatabilit...

OBJECTIVE To evaluate the effect of temperature on sperm motility, sperm motion characteristics, and production of reactive oxygen species (ROS) in semen. METHODS We collected semen samples from 12 infertile patients and 12 healthy donors and divided each sample into four aliquots just after liquefaction. One aliquot was analyzed immediately after liquefaction and the remaining three were ana...

The aim of this study was to evaluate the motor activity of the interposed colonic segment in patients who had received a colonic replacement following radical esophagectomy using spectral analysis and a 24 hr activity graph. The 24-hr ambulatory pressure waves were recorded in the replaced colon after esophagectomy (n=8) using a solid-state manometric catheter (MicroDigitrapper, Synetics). Mot...

Variations in the ejaculatory abstinence durations suggested by different guidance bodies have resulted in a growing concern among researchers over what the concise period of ejaculatory abstinence for an optimal semen sample ought to be. Several studies have been undertaken to examine the association between the length of sexual abstinence and semen characteristics. Not all studies, however, h...
