AbADjievA, D., M. Chervenkov, r. StefAnov, n. MetoDiev, e. kiStAnovA, D. kAChevA and e. rAyChevA, 2014. effect of breeding season on the kinematic parameters and morphology of ram’ sperm from synthetic population bulgarian milk sheep breed. Bulg. J. Agric. Sci., 20: 967-972 the aim of this study was the investigation of the breeding season effect on the kinematic and main spermatological parame...
Probiotics have been proposed as alternatives to pharmacological products in several medical conditions including the modulation of obesity, which is frequently associated with poor semen quality. However, effects of probiotics on male fertility have been less investigated. This study assessed the effect of Lactobacillus rhamnosus PB01 (DSM-14870) on sperm kinematic parameters in Normal-weight ...
Ejaculated, density purified, human spermatozoa were exposed to pulsed 900 MHz GSM mobile phone radiation at two specific absorption rate levels (SAR 2.0 and 5.7 W/kg) and compared with controls over time. Change in sperm mitochondrial membrane potential was analysed using flow cytometry. Sperm motility was determined by computer assisted sperm analysis (CASA). There was no effect of pulsed 900...
This work provides information on the blue fox ejaculated sperm quality needed for seminal dose calculations. Twenty semen samples, obtained by masturbation, were analyzed for kinematic and morphometric parameters by using CASA-Mot and CASA-Morph system and principal component (PC) analysis. For motility, eight kinematic parameters were evaluated, which were reduced to PC1, related to linear va...
Background: This study aimed to investigate the inhibitory effects of simultaneous formaldehyde (FA) and noise exposure on the sperm kinematic parameters sexual hormones in male mice. Materials and Methods: Forty eight NMRI adult male mice were randomly assigned to control group and experimental groups which were exposed to formaldehyde vapour (10 ppm) (F), noise (100 dB) (N), and simultaneous ...
The goal of this study was to examine the effect of palmitoylethanolamide (PEA) on the capacitation process and hyperactivated motility (HA) in idiopathic infertile men. Our data show the effect of PEA on the kinematic parameters of sperm cells from idiopathic infertile men during the capacitation of spermatozoa in vitro, both in the presence and absence of 2.5 nM PEA, a molecule physiologicall...
Background: Detection of sperm parameters based on conventional methods, immediately after thawing, have been revealed sperm capacity to in vivo and in vitro fertilization. But this evaluation is not fully reliable because of long journey of sperm during female genital tract to reach the oocyte and fertilize it. Therefore, analyzing postthawed sperm parameters after incubation is more beneficia...
This study was designed to analyze the sperm kinematic and morphometric subpopulations in the different fractions of the ejaculate in normozoospermic men. Ejaculates from eight normozoospermic men were collected by masturbation in three fractions after 3-5 days of sexual abstinence. Analyses of sperm motility by computer-assisted sperm analysis (CASA-Mot), and of sperm morphometry by computer-a...
Background: Fertilization and fecundation obviously are the phenomenon in which several factors are involved. Sperm membranous proteins are a series of these important elements. CD9, an inner acrosomal membrane protein, is one of the tetraspanin members that involved in sperm-egg fusion. CD52, is a GPI anchor protein which is expressed in the epididymal cells and during passage of sperms throug...
BACKGROUND Volume regulation is an important sperm function because defective sperm cannot negotiate the female tract in an infertile mouse model and swollen human sperm cannot penetrate and migrate through mucus. METHODS AND RESULTS The size of sperm from 52 donor ejaculates incubated in medium of female tract fluid osmolality (BWW290) was measured by flow cytometry to be identical to that i...
