conclusions: saffron, as an antioxidant, is positively effective on sperm parameters in rats exposed with cadmium. objectives: the aim of this study was to determine the effects of saffron on the results of semen parameters (sperm concentration, motility and viability in cauda of epididymis) in rats exposed to cadmium. materials and methods: thirty wistar male rats were divided into four groups...

background:  wi-fi allows electronic devices such as laptops to exchange data or connect to a network resource. the main goal of this study was to assess the bioeffects of short term exposure to 2.4 ghz microwave radiation emitted from a common wi-fi router on sperm quality. materials and methods: male wistar rats were divided into 7 groups; i, sham exposed 4 h/day for 7days at 30 cm from the r...

introduction: pyrethroids are important insecticides because of their high activity and low mammalian toxicity. some studies have demonstrated that these insecticides, especially compounds with an -cyano group, produce toxic effects on various biological systems. deltamethrin (dtm) is a type ii synthetic pyrethroid insecticide containing -cyano group and is used worldwide in agriculture, home...

background: to determine any correlation between infertility and semen quality with concentrations of l-carnitine in human seminal plasma. methods: this case-control study performed in fatemieh hospital in hamadan, iran. seminal plasma of 72 infertile men and 80 men with proved fertility as a control group was investigated and l-carnitine level was determined using uv enzymatic test at 340 nm. ...

The objective of this study was to compare (i) the intracytoplasmic sperm injection outcomes among groups with different total motile sperm count ranges, (ii) the intracytoplasmic sperm injection outcomes between groups with normal and abnormal total motile sperm count, and (iii) the predictive values of WHO 2010 cut-off values and pre-wash total motile sperm count for the intracytoplasmic sper...

background: long term alcohol use has been implicated in men with sexual disorders including suppression of testosterone levels as well as testicular morphological changes. objective: this research investigated the ability of telfairia occidentalis (t.o.) to attenuate the damaging effects of alcohol on the testicular parameters. materials and methods: thirty male sprague-dawley rats, 170-190 gr...

background: the antifertility effect of ampicillin (amp, 40 mg/kg) and sulphasalazine or salicylazosulfapyridine (sasp, 300,450 and 600 mg/kg) in male rats has been reported earlier. the combination of amp and sasp is generally used in certain pathological conditions, but the combined effect of these two drugs on the fertility is not clear. so, the aim of this study was to investigate the antif...

The present study to investigate that the correlation between sperm parameters and sperm DNA fragmentation in fertile and infertile cigarette smoking patient. Forty men undergoing infertility evaluation were divided into four groups according their smoking ability (A: 2 days ( n=10), B: 4 days ( n=10), C: 8 days ( n=10), D: 15 days ( n=10)) sperm parameters ( sperm concentration, pH, Viscosity,...

Background: Obesity and increased body mass index (BMI) affect the reproductive parameters in men such as poor semen quality, decreased sperm concentration, decreased normal-motile sperm cells and increased DNA fragmentation index. Lipid peroxidation contributes to the damage of the sperm plasma membrane. The Curcuma Longa is a resource of antioxidants, hence in this study also was evaluated th...
