The Rockefeller University Press $30.00 J. Gen. Physiol. 2016 Vol. 148 No. 3 207–211 www.jgp.org/cgi/doi/10.1085/jgp.201611676 207 Key physiological functions of organisms, such as sensory transduction, regulation of heart rate, smooth muscle contraction, bile secretion, endocrine regulation, immune responses, and various pathophysiological conditions, including neuropathic pain, diabetes, kidn...
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: male are involved in near 50% of cases of infertility and reactive oxygen species (ros) playing an important role in decreasing fertility potential. accurate measurement of ros seems to be important in evaluation of infertile male patients. objective: to compare ros measurement in neat and washed semen samples of infertile men and define the best method for evaluation of ros in thes...
in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...
INTRODUCTION Bisphenol A (BPA) and Nonylphenol (NP) have estrogen-like activity, and some of their adverse biological effects have been demonstrated. This study was designed to determine the association of plasma and tissue concentrations of BPA and NP and changes in the parameters of the reproductive system in rats. METHODS Male Wistar rats were administered three doses of BPA and NP (5, 25,...
The effect on sperm motility of sperm-sperm and sperm-seminal plasma interactions was studied among homologous and heterologous sperm. There were no significant interactions between sperm in vitro, but it was found that seminal plasmas of different donors have different effects on sperm motility, and different sperm react differently to the same seminal plasma. Sperm showed higher motility in a...
Background: Sperm analysis is an initial detection procedure of male infertility recommended by the WHO. motility as one important parameters in sperm has a close correlation with various determinants and success Assissted Reproductive Technology (ART). Several laboratory assays were carried out complement to describe ability for fertilization. One was modified stress test (MOST) predict oocyte...
Background Chlamydia trachomatis (CT) with damaging effects on sperm quality parameters can often cause infertility in men. Objective The main objective of this study was to determine the diagnostic value of polymerase chain reaction (PCR) and enzyme linked immuno sorbent assay (ELISA) for screening and detecting CT in semen samples of infertile men. Materials and Methods In this cross-sect...
The aim of the present study was to evaluate the effect of sperm reactive oxygen species (ROS) production and DNA changes on male fertility. For that purpose, six rams with significantly different pregnancy rates were used; these were classified as having high fertility, i.e. 59.4% average pregnancy rate, or low fertility, i.e. 23.1% average pregnancy rate. Sperm quality was assessed after a tw...
Short-term storage of fish sperm is a simple and cost-effective process in fishery research from basic to applied perspectives. It has been used elucidate evaluate gamete biology quality, perform vitro fertilization, develop cryopreservation. Sperm short-term selective breeding, hatchery production advanced molecular investigations such as disease detection commercial species aquaculture well b...
