INTRODUCTION The aim of this study was to evaluate the effect of microsurgical subinguinal varicocelectomy on semen parameters in azoospermic men with clinical varicocele and to determine the predictive parameters of postoperative improvement. METHODS Twenty-three men with non-obstructive complete azoospermia and varicocele underwent subinguinal open microsurgical varicocele repair. The outco...

GOGOL P. 2013. Motility parameters and intracellular ATP content of rabbit spermatozoa stored for 3 days at 15°C. Folia Biologica (Kraków) 61: 87-91. The effect of semen storage duration on motility parameters and ATP content of rabbit spermatozoa were investigated. Ejaculates were collected from 9 New Zealand White male rabbits and diluted with a commercial rabbit semen extender Galap. Semen w...

Background: The study aimed to evaluate the impact of Calligonum extract and US radiation on sperm parametersof cryopreserved human semen samples.Materials and Methods: In this experimental study, twenty-five semen specimens were obtained from healthy semendonors and incubated in human tubal fluid (HTF) medium supplemented with 10% human serum albumin (HSA) for45 minutes...

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...

Background: Studies suggest that global semen quality is declining, but the debate remains open owing to geographic variation. Objectives: To evaluate temporal trends of sperm parameters – namely concentration, motility and total motile sperm count – in sperm donated during the period 1995–2009. methods: In a retrospective longitudinal cohort study we analyzed the sperm count and motility of 21...

Background: Infertility affects 15% of couples around the world. Male factor accounts for 40-50% of conjugal infertility. cAMP responsive element modulator (CREM) is a key factor in the regulation of the expression of number of postmeiotic genes that control spermatogenesis. Aloe vera is a medicinal plant used to treat several diseases. The purpose of this study was to investigate effects of Al...

A field trial was conducted to compare the fertility predicting capacity of different sperm assays applying classical semen analysis, sperm function and the homologous in vitro penetration test (hIVP) to 60 ejaculates from four boars collected over a period of 15 weeks. No differences were found between the groups of fertility (Low Fertility: < 20%; Intermediate: 40-60% and High: > 80%) for spe...

BACKGROUND Previous researches about the effect of smoking on semen quality are contradictory, and the mechanism behind the harmful effect of smoking on semen quality still remains unclear until today. OBJECTIVE The objectives of this study are evaluation of the relationship between smoking and fertility, investigation of the effects of cigarette smoking on sperm parameters and detection of p...

Semen analysis, sperm DNA fragmentation (SDF) and hypo-osmotic swelling test (HOST) are usually performed for the evaluation of sperm fertilizing ability. There are some debates over the necessity of SDF and HOST incorporation in male infertility work-up.Semen of 77 men was evaluated by SDF and HOST through three semen analyses. Sperm parameters were arranged into different categories: <5%, 5-1...
