background: nano-particles are extensively employed in most industries. several studies have been started to explore the probable detrimental effects of nano-particles on human reproduction. however, there is insufficient and controversially evident of effects of silver nano-particles on sperm parameters and other reproductive indices. objective: investigation of the effects of silver nano-part...

background: para-nonylphenol (p-np) is able to induce malformations in male reproductive system. objective: the aim of this study was to investigate the preventing role of vitamin e (vit.e) on sperm parameters and reproductive hormones in developing rats. materials and methods: pregnant rats were divided into 4 groups: control p-np vit.e and p-np+vit.e. treatments were performed on day 7 of ges...

objective: the effects of dietary fish oil on semen quality and sperm fatty acid profiles during consumption of n-3 fatty acids as well as the persistency of fatty acids in ram’s sperm after removing dietary oil from the diet were investigated. materials and methods: in this experimental study, we randomly assigned 9 zandi rams to two groups (isoenergetic and isonitrogenous diets): control (ctr...

Background: Although sperm selection according to morphologic and motility characteristic, made to some what the fertility successful, but sperm’s normal morphology cannot demonstrate sperm DNA competence. Since the health of sperm DNA is affecting the results of assisted reproductive technology; the aim of this study is to evaluate semen parameters measured by CASA with sperm chromatin abnorma...

CONTEXT Air pollution is common in all countries and affects reproductive functions in men and women. It particularly impacts sperm parameters in men. This meta-analysis aimed to examine the impact of air pollution on the quality of sperm. EVIDENCE ACQUISITION The scientific databases of Medline, PubMed, Scopus, Google scholar, Cochrane Library, and Elsevier were searched to identify relevant...

background: there are few studies indicating the detrimental effects of ibuprofen on sperm fertility potential and dna integrity. objective: to determine the effects of ibuprofen on sperm parameters, chromatin condensation and dna integrity of mice. materials and methods: in this experimental study, 36 adult male mice with average weight 37 gr were divided into three groups, including control (...

PURPOSE Our aim was to evaluate the effect of neat semen vitrification on human sperm vital parameters and DNA integrity in men with normal and abnormal sperm parameters. MATERIALS AND METHODS Semen samples were 17 normozoospermic samples and 17 specimens with abnormal sperm parameters. Semen analysis was performed according to World Health Organization (WHO) criteria. Then, the smear was pro...

The aim of the present study was to evaluate the effects of different seasons on the morphometric testicular parameters and the respective epididymal sperm parameters. Total numbers of 104 scrota of pubertal buffalo bull (24-48 months) include their contents were provided from the local slaughterhouse. Scrotal circumference was measured on its place before dissection. Morphological parameters o...

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,...

introduction: to evaluate and compare efficiency of sil-select with percoll to recover sperm with normal chromatin in morphology and also studyeffect of these parameters on fertilization, embryo quality and cleavagescore. materials and methods: assessment of semen parameters, protamine deficiency (cma3) and excessive histone (aniline blue staining) were carried out before and after sperm proces...
