In this study we aimed to examine the effects of genetic variants of GSTM1 and GSTP1 (Ile105Val and Ala114Val) on GST activity, seminal oxidative stress and sperm chromatin status in infertile men with oligoasthenoteratozoospermia (OAT). The study population (n=121) consisted of 95 infertile men with OAT and 26 controls with normozoospermia. Multiplex polymerase chain reaction (PCR) and polymer...

OBJECTIVE Growth hormone and its mediator, insulin-like growth factor-1 (IGF-1), have been suggested to exert gonadotropic actions in both humans and animals. The present study was conducted to assess the relationship between serum IGF-1 concentration, seminal plasma concentration, and sperm parameter abnormalities. METHODS A total of 79 men were enrolled in this study from December 2011 to J...

Inositol (me8oinositol or myoinositol) occurs very widely in plants, animals and micro-organisms (Fleury & Balatre, 1947; Courtois, 1951; Hawthorne & Chargaff, 1954; Mann, 1954a). It occurs in the free state as well as in the form of inositol phosphatides, while in plants it is often present as the hexaphosphate, phytic acid. Treatment of liver and nervous tissue by the standard procedure of Sc...

Potentially damaging species (reactive oxygen, nitrogen and chlorine species) arise as by-products of metabolism and as physiological mediators and signalling molecules. Levels of these species are controlled by the antioxidant defence system. Several components of this system are micronutrients (e.g. vitamins C and E) or are dependent upon dietary micronutrients (e.g. CuZn and Mn superoxide di...

Abnormal reactive oxygen species (ROS) production is associated with defective sperm function. Superoxide dismutase (SOD) is related with the scavenging of seminal ROS. We aimed to determine the effect of SOD activities of spermatozoa and seminal plasma on sperm quality. Semen samples from infertile couples who consented to the analyses were divided into two groups: 1) normospermia (n = 20); an...

conclusions therefore, our results suggest that although administration of 300 mg/kg of calendula officinalis extract showed salutary effects on anti-oxidant profile, yet its protective effects on anti-diabetic and regenerative properties on nephropathy were ambiguous and require more investigations. background chronic hyperglycemia leads to microvascular and macrovascular complications such as...
