objective: the effects of dietary fish oil on semen quality and sperm fatty acid profiles during consumption of n-3 fatty acids as well as the persistency of fatty acids in ram’s sperm after removing dietary oil from the diet were investigated. materials and methods: in this experimental study, we randomly assigned 9 zandi rams to two groups (isoenergetic and isonitrogenous diets): control (ctr...
Background: The motility patterns of spermatozoa correlate with the rate of natural pregnancy. It is not clear which compounds in spermatozoa or seminal plasma may be involved in the regulation of sperm motility. Considering the decrease of omega-3 fatty acids in spermatozoa of asthenozoospermic men, the aim of the present study was to investigate the effects of combined docosahexaenoic acid (D...
Lead is a heavy metal which is reported to have toxicological effects on various organs in humans and animals. Due to its toxicological effects this study reviews current literature on the toxicological profile of lead on the testis, bone, blood and lungs and the possible roles of mitigating agents. In this study reports showed that in the brain lead induced cerebellar edema, cerebral satellito...
PURPOSE Epilepsy has an impact on the reproductive system. Males with epilepsy have lower fertility rates, hypo-sexuality and reduced potency compared with the general population. Anti-epileptic drugs and epilepsy itself are thought to be responsible for this reduced fertility. LEV is a second-generation anti-epileptic agent with low incidences of both adverse effects and drug-drug interactions...
background: it has been shown that reactive oxygen species (ros) can lead to deleterious effects on a range of sperm parameters. vitamins e and c are capable of reducing ros levels and lipid peroxidation. objective: the aim of study was to determine the level of lipid peroxidation as indicated by malondialdehyde (mda) and vitamins e and c in sperm and seminal plasma of asthenoteratozoospermic a...
The objective of this study was to evaluate quality of frozen-thawed bull semen processed with extenders containing vitamin C and E as antioxidants. Pooled semen's were collected from 5 bulls and diluted to a concentration of 30 × 10 6 sperm/mL with citrate –egg yolk (CEY) or Tris – egg yolk (TEY) extenders. The diluted semen was divided to 5 aliquots including control and 4 experimental groups...
Introduction & Objective: Sodium arsenite disturbs the differentiation of adult rat bone marrow mesenchymal stem cells (rMSCs) to Osteoblast through oxidative stress. We aimed to investigate the preventive effect of vitamin E, a strong antioxidant, in sodium arsenite toxicity on rMSCs differentiation to osteoblast. Materials & Methods: rMSCs were cultured in Dulbecco’s Modified Eagles Medium...
This study was aimed to assess the protective effects of Cornus mas fruit extract (CMFE) and vitamin E (Vit E) on sperm quality parameters in the methotrexate (MTX)-treated mice. Forty-eight young adult male mice (8-12 weeks) were randomly divided into six groups including control and test groups. The control group received normal saline orally , and the test groups were treated MTX (20 mg kg(-...
Many industrial and agricultural chemicals (including heavy metals and alkylphenols) present in the environment have adverse effects on the reproductive function in fish. Three studies were conducted to assess toxicity of these chemicals towards reproduction of freshwater fish. It was shown that heavy metals added to the diets accumulate in brain tissue of carp, and this accumulation results in...
Background: Considering the decrease of omega-3 fatty acids in spermatozoa of asthenozoospermic men, the aim of the present study was to investigate the effects of combined docosahexaenoic acid (DHA) and vitamin E supplements on spermatogram in asthenozoospermic males. Methods: In this randomized, triple-blind , placebo-controlled clinical trial, out of 275 men who referred to Avicenna infe...
