Background. Male infertility is one of the most serious medical and social problems. Idiopathic accounts for about 30 % cases infertile men. Rheumatoid arthritis associated with a decreased fertility potential. The aim present work was to determine lipid peroxidation level activity antioxidant enzymes such as glutathione peroxidase reductase in seminal plasma blood men idiopathic concomitant au...

evidence acquisition literature searching for studies on female infertility and micronutrient intakes, published between january 1984 and november 2014, was performed using the pubmed and embase databases. the bibliographies of included studies were also searched for additional references. results about 100 articles were identified and after the elimination of irrelevant studies, 28 related stu...

A large number of human diseases arise as a result of genetic abnormalities. With the advent of improved molecular biology techniques, the genetic etiology of male infertility is increasing. The common genetic factors responsible for male infertility are chromosomal abnormalities, Yq microdeletion and cystic fibrosis. These are responsible for approximately 30 percent cases of male infertility....

Introduction and Aim: Idiopathic infertility accounts for at least 30% of all cases infertility, oxidative stress has been identified as a novel developing factor in idiopathic male infertility. Oxidative occurs when antioxidant defense mechanisms are outmatched by the creation reactive oxygen species (ROS). The purpose this research was to examine impact enzymatic antioxidants (catalase supero...

OBJECTIVE To examine the effects of increased sperm DNA damage in relation to seminal oxidative stress in men with idiopathic and male factor infertility. Prospective study. SETTINGS Infertility clinic at a tertiary care academic institution. PATIENT(S) Ninety-two infertile men with normal female partners. Sixteen fertile donors served as the control group. INTERVENTION(S) Standard semen ...

Infertility remains a significant problem for many couples. Approximately one in seven couples who attempt to conceive will fail to do so within 1 year. In about 65% of these cases, there is a male component of infertility.1 Despite normal semen parameters, the etiology of infertility remains uncertain in more than 50% of couples.2 Defects in sperm proteins and/ or structures may underlie certa...

sting by E Abstract Introduction: Intrauterine insemination (IUI) is a valid treatment for infertility with a cumulative pregnancy rate of 40–90% after 3–10 treatment cycles. Design: We prospectively studied the efficacy of a new simplified method for motile sperm preparation for IUI for both male causes of infertility, and for those diagnosed with idiopathic infertility. Methods: A prospective...

Context: Oxidative stress is one of the factors related to the pathogenesis of fertility disorders such as idiopathic infertility, polycystic ovarian syndrome, and endometriosis. Hence, the role of micronutrients has attracted the attention of researchers to the extent that some studies have investigated the role of vitamins and minerals in the risk of female infertility. This study aimed to su...

BACKGROUND The proteolytic chaperone peptide ubiquitin accumulates in defective human spermatozoa. Immunodetection of ubiquitin in human sperm samples correlates with semen quality and male fertility. METHODS Semen samples from 93 men from couples seeking infertility treatment were separated on a PureSperm density gradient and screened by immunofluorescence microscopy with anti-ubiquitin anti...

AIM To establish the frequency of Y chromosome microdeletions in an unselected group of infertile Croatian men. METHODS An unselected group of 105 patients (male partners of infertile couples), both with idiopathic and non-idiopathic infertility, consecutively referred to the outpatient infertility clinic, gynecology department, General Hospital Pula, Istria County, Croatia, was examined for ...
