The Protective Effect of Quercetin on Sperm Parameters and Serum Biochemical Factors in Adult Mice Treated with Dexamethasone

Background and Objectives: Dexamethasone is a synthetic glucocorticoid, which causes oxidative stress in the testicular tissue. This study aimed to investigate the protective effect of quercetin as a powerful antioxidant on sperm parameters and serum biochemical factors in mature adult mice following the treatment with dexamethasone.   Methods: In this experimental study, 24 mature adult male ...

Protective Effect of Spirulina and Phycocyanin on Testicular Tissue and Sperm Parameters in Adult Rats Treated with Hydrogen Peroxide

 Background and purpose: About 50% of infertility in couples is related to male factors and oxidative stress is one of the main causes of infertility in men. Hydrogen peroxide has an adverse effect on male reproductive system due to its free radicals. Spirulina and phycocyanin are known to have antioxidant properties and can modify stressors. Materials and methods: In this experimental study, ...

Preventive and therapeutic role of garlic on the epididymis and seminal vesicle of male diabetic rats

Introduction: Diabetes has adverse effects on reproductive functions in human. Clinical as well as experimental studies revealed impairment of spermatogenesis, reduced volume of seminal fluid and atrophic changes in epididymis. In the present study, we aimed to investigate the preventive and therapeutic effect of garlic juice on epididymal and vesicle seminal damage in male rats with stre...

Protective effect of royal jelly on the sperm parameters and testosterone level and lipid peroxidation in adult mice treated with oxymetholone

Objectives: The aim of the present study was to evaluate protective effect of royal jelly on sperm parameters, testosterone level, and malondialdehyde (MDA) production in mice. Materials and Methods: Thirty-two adult male NMRI mice weighing 30±2 g were used. All the animals were divided into 4 groups. Control group: received saline 0.1 ml/mouse/day orally for 30 days. Royal Jelly group (RJ): re...
