Objective(s): Melatonin, an important hormone secreted by the epiphysis, is a powerful anti-oxidant with a high potential to neutralize medical toxins. The goal of this study was to demonstrate the beneficial effect of melatonin on epididymal sperm and reproductive parameters in mice treated with acetylsalicylic acid (ASA). Materials and Methods: Male adult mice were divided into four treatment...

Human motion capture is a promising technique for the generation of humanoid robot motions. To convert human motion into humanoid robot motion, we need to relate the humanoid robot kinematics to the kinematics of a human performer. In this paper we propose an automatic approach for scaling of humanoid robot kinematic parameters to the kinematic parameters of a human performer. The kinematic mod...

BACKGROUND Treatment of differentiated thyroid cancer usually consists of a total thyroidectomy followed by one or several courses of radioiodine ((131)I). (131)I is known to have deleterious effects on radiation sensitive tissues and irradiation to the testes has been shown after its administration. We investigated effects of such treatment on sperm DNA in a patient with differentiated thyroid...

background: active immunization against gnrh decreases the secretion of gonadotropins and causes cessation of gonadal function, thereby, inducing infertility. based on the immunoenhancing activity of kamdhenu ark (distilled cow urine), this study was performed to evaluate its effects on the gonadosomatic indices (gsi) and sperm parameters in male mice receiving a gnrh contraceptive vaccine. met...

Recent studies show that spermatozoal DNA integrity is essential for normal fertilization and transmission of paternal genetic information to the offspring. Additionally, fertilization and embryo development depend on the sperm DNA structure (1,2). Generally, while fertile men have high levels of sperm with intact DNA...

oxidative stress is one of the important causes of the type 1 diabetes induced changes in the sperm quality. bioflavonoids, rutin 10 mg/kg and naringin 10 mg/kg were evaluated for their protective effects on sperm parameters, oxidative stress, and histopathology of type 1 diabetic rats. results demonstrated the reduction in sperm count, sperm motility and vitality in diabetic rats. mass drug ad...

Osmotic stress is an important factor that can result in cell damage during cryopreservation. Before ejaculation or collection for cryopreservation, murine spermatozoa are stored in epididymal fluid, a physiologically hyperosmotic environment (approximately 415 mmol/kg). The objectives of this study were to determine the osmotic tolerance limits of sperm motion parameters of ICR and C57BL/6 mou...

In humans, it is widely demonstrated that maternal obesity negatively affects fertility, pregnancy outcomes and offspring’s health. Less is known about the effects of paternal obesity on fertility and offspring’s development. Recent observations in animal models show that dietinduced obese males have impaired sperm quality, delayed preimplantation growth of the fertilized oocyte, and reduced im...

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: Vitamin E is believed to be the primary component of the antioxidant system in spermatozoa. There is a relationship between activity of these antioxidant and function of sperm. Vitamins E and C which are belong to non-enzymatic antioxidant are used as a supplemented drug to improve sperm quality and male fertility. The present study was carried out to investigate the positive effect...
