Objective: Using correlation analysis between the sperm spontaneous acrosome reaction rate (SARR) and routine semen parameters in male infertility patients, we explored the value of the sperm spontaneous acrosome reaction in the evaluation of sperm functions. Methods: The participants comprised of 219 male infertility patients who had visited the Center for Reproductive Medicine, Shandong Unive...

As the chemical environment of semen can have a profound effect on sperm quality, we examined the effect of pH on the motility, viability and capacitation of human sperm. The sperm in this study was collected from healthy males to avoid interference from other factors. The spermatozoa cultured in sperm nutrition solution at pH 5.2, 6.2, 7.2 and 8.2 were analyzed for sperm total motility, progre...

OBJECTIVE To determine the frequency of and factors associated with delayed vasectomy success in men with first postvasectomy semen analysis showing motile sperm. DESIGN Descriptive study. SETTING One hospital-based family planning clinic and two private clinics from the Quebec City area, Canada. PATIENT(S) Three hundred nine men vasectomized between 1990 and 2001 and who had a first seme...

BACKGROUND The aneuploidy rate is higher in poor-quality sperm samples, which also have higher DNA fragmentation index values. The aim of this study was to assess the relationship between sperm DNA fragmentation in samples from infertile men belonging to couples with recurrent miscarriage or implantation failure and the aneuploidy rate in spermatozoa as well as in embryos from patients. METHO...

The effect of Ovaprim (salmon GnRH analogue and a dopamine antagonist) treatment on the quantity and quality of smelt (Osmerus eperlanus L.) sperm was studied in relation to time after hormonal stimulation. Sperm was obtained at 0, 24, 48 and 72 h after treatment (n=13/each time point). Computer Assisted Sperm Analysis (CASA) was used to evaluate sperm motility parameters and histological analy...

the main objective of this study was assessment of hormonal treatments effects on sperm quality improvement in barbus sharpeyi. results showed differences in effects of treatments with lhrha2, lhrha2 combined with a dopamine antagonist (met), and cpe (carp pituitary extract) on parameters of sperm volume, motility, spermatocrit, biochemical indices of seminal plasma and sperm efficiency on arti...

The research aims to evaluate proportion of X-Y chromosom bearing sperm after sexing local ram semen with different combination BSA concentration. object was ten ejaculated ram, three years old. design used CRD (completely randomize design) four treatments concentration on upper and bottom layer (T1: 3% & 6%, T2: 4% T3: 5% 10%, T4: 6% 12%), 10 repetitions. Data analysis using variance Dunca...
