Kozdrowski R., A. Dubiel, W. Bielas, M. Dzięcioł: Two Protocols of Cryopreservation of Goat Semen with the Use of Computer-Assisted Semen Analysis System.Acta Vet. Brno 2007, 76: 601-604. The objective of the study was a comparison of two protocols of goat semen cryopreservation with the use of computer-assisted semen analysis system. Twenty ejaculates obtained with electroejaculation method we...
The aim of the present study was to assess variability in the evaluation of human sperm concentration, motility and vitality. Technicians and biologists from 10 teams involved in multicentre studies on semen quality attended the same laboratory, each team using its own methods and equipment to analyse the same semen samples. Inter-individual variability was assessed from 17 fresh semen samples ...
The sperm quality index (SQI) is a tool used to predict overall rooster semen quality, fertility, and hatchability. However, semen must be diluted before SQI analysis, and research has shown that the SQI is most predictive of fertility at lower semen dilutions. Therefore, the present study was undertaken to determine why the SQI is not as predictive of fertility at higher semen dilutions and wh...
OBJECTIVE The objective of this study is to estimate the effects of Inclear, a feminine cleanser, on sperm motility. METHODS Semen samples were obtained from infertile male patients. Following liquefaction, the raw semen samples were diluted with Ham's F-10 nutrient mixture medium containing 0.4% human serum albumin solution at a ratio of 1:3. The semen samples were subsequently centrifuged t...
Background Fertility disorder is a multifaceted physiopathological condition comprising men’s or women’s impotence in fertility or a combination of both. Men’s debility in fertilization is the main culprit in 40-50 percent of the studied cases. The first step in scrutinizing infertility is to analyze semen. So, the assessment hinges on analyzing factors like sperm density, total count and motil...
Introduction: Diabetes Mellitus (DM) is a chronic metabolic disease that affects all the physiological systems of the body and recently, the age of suffering from DM has decreased. The aim of this study was to assess the semen parameters of males with DM type 2 and non-diabetic males without any metabolic disorders. Methods: This study was a case-control study. In this study, semen samples wer...
This study was conducted to determine chromatin integrity and DNA damage by DNA electrophoresis and comet assays of buffalo fresh and frozen semen. Semen samples were collected from four buffalo bulls and evaluated after freezing for semen motility, viability, sperm abnormalities, chromatin integrity and DNA damage. A significant variation was found in semen parameters after thawing. Highly sig...
Abstract Semen volume is the amount of ejaculate released by male Bali cattle during one ejaculation, which consists spermatozoa and seminal plasma. The purpose this study was to determine effect ejaculation on quality fresh frozen semen. collection carried out using an artificial vaginal method. collected semen then evaluated with microscopic parameters: motility, viability, abnormalities. cam...
Oxidative stress, resulting from excessive levels of ROS in semen, has a negative impact on functional parameters and sperm fertility. In this study we examined the influence of the oxidative stress induced by hydrogen peroxide (H2O2) in ovine sperm motility after thawing and catalase (CAT) ability to preserve sperm motility. Semen was incubated at 37°C with 100 μM H2O2, 1 U catalase + 100 μM H...
background: pentoxifylline (px) is a methyxanthin derivative that influences the sperm motion characteristics. in general, px has been reportedly effective in preserving sperm motility in vitro, also when administered orally to the asthenozoospermic patients. objective: the main objective of this prospective clinical trial study was to rule out the effect of oral administration of px on sperm p...
