In this study the effect of Boswellia papyrifera (B. papyrifera) and Boswellia carterii (B. carterii) smoke exposure on spermatogenesis and sperm parameters in male albino rats was investigated. Rats (n = 11) were exposed daily in smoking chambers to smoke emanated by burning 4 g each of either B. papyrifera or B. carterii for 48 days. At the end of exposure duration rats were killed, and the t...

Chronic bacterial prostatitis (CBP) is caused by bacterial infection and maintains a condition of lower urinary tract infection. It may be a cause of male infertility. However, studies showed inconsistent results regarding the effect of CBP on several parameters of semen. Hence, we conducted a meta-analysis to examine the effect of CBP on basic semen parameters. A systematic review was conducte...

OBJECTIVE This study aims to evaluate the protective effects of American ginseng administered by gastric intubation on sperm vital quality in adult male rats treated with cyclophosphamide (CP). MATERIALS AND METHODS In this experimental study, 28 Adult male Wistar rats were assigned to four groups, seven rats in each. The animals allocated to control, CP treated, Ginseng treated and CP-Ginsen...

Background: The aim of this study was to compare the sperm protein profile between oligo- and normozoospermic patients with varicocele. Materials and Methods: Sperm samples of 20 normozoospermic and 20 oligozoospermic patients with varicocele were characterized using two dimensional electrophoresis (group 1 and group 2, respectively). Differences in protein expression were established using gel...

New advances in mass spectrometry-based proteomics technology are having a major impact on our understanding of how human spermatozoa acquire their capacity for fertilization. A complete analysis of the proteins found in the human spermatozoa is essential for understanding the events leading up to, and including, fertilization and early embryo development. In this short review, we have collecte...

Cooling method was proposed to maintain the sperm quality for several days. Nevertheless, during this procedure, sperm is encountered to “cold shock”, and its quality decreases time-dependently. This study was designed to improve the in vitro sperm preservation methods. Thirty normal semen samples were examined in Shiraz, Iran, 2017. Fifteen samples were incubated at 22-27 °C and 15 samples wer...

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. conclusions the results of this meta-analysis showed that air pollution reduces sperm motility, but has no impact on the other sperm parameters of spermogram...

Topological Designs In article number 2207393, Jun Chen, Weiqing Yang, Weili Deng and co-workers, developed topological designs to enhance the electromechanical response, for electrospun piezoelectric membranes, which show a 300% increase in electric output 478% frequency response range compared with traditional membranes. It represents milestone designing membranes conversion high-performance ...
