BACKGROUND Although semen analysis is routinely used to evaluate the male partner in infertile couples, sperm measurements that discriminate between fertile and infertile men are not well defined. METHODS We evaluated two semen specimens from each of the male partners in 765 infertile couples and 696 fertile couples at nine sites. The female partners in the infertile couples had normal result...
Background and aim: given the high prevalence of bacterial infections, particularly the E.coli in the semen of infertile men compared to fertile men and according to the controversial reports on the association of E.coli with male infertility, herein, the prevalence of this bacterium in the semen of infertile men and its possible association with parameters determining sperm fertility was evalu...
OBJECTIVE To compare semen quality and levels of seminal oxidative stress among three groups: infertile men with varicocele, fertile men with varicocele, and healthy semen donors (controls) without varicocele. DESIGN Prospective study. SETTING Academic medical centers. INTERVENTION(S) None. PATIENT(S) Semen specimens were obtained from 21 infertile patients with varicocele, 15 fertile m...
background: infertility is a major reproductive health in gynecology. according to the world health organization, there are currently 50-80 million infertile couples in the world. objective: considering the critical effects of lifestyle on reproductive health, this study aimed to compare the lifestyle of fertile and infertile couples in kermanshah during 2013. materials and methods: this resear...
results genotype frequencies of g/a in fertile and infertile men were significantly different (χ2 = 4.16, df = 1, p = 0.041). genotype frequencies of g/g and a/ain fertile and infertile men were not significantly different (χ2 = 3.32, df = 1, p = 0.068 and χ2 = 0.521, df = 1, p = 0.47, respectively). the risk of infertility was 1.43 folds higher in individuals with the a/a genotype compared to ...

BACKGROUND Oxidative DNA damage is associated with male infertility. The aim of this study was to evaluate the oxidative DNA damage of sperm cells and blood leukocytes and to determine the levels of MDA and NO levels in seminal and blood plasma of idiopathic infertile men. MATERIAL AND METHODS The study enrolled 52 patients, including 30 infertile and 22 fertile men. MDA, NO, and 8-OHdG/106dG w...
Objective Matrix Metalloproteinase (MMPs) play important roles in the structural and functional properties of reproductive organs. The aim of this study is to determine the prevalence of C-1562T Matrix Metalloproteinase-9 (rs3918242) gene polymorphism in fertile and infertile men. In addition, we aimed to determine the association between C-1562T MMP-9 and G-1575A MMP-2 gene polymorphisms. Mate...
We determined the association of androgen receptor (AR) (CAG)n lengths among fertile and infertile males and offspring conceived by intracytoplasmic sperm injection (ICSI). Assessment of (CAG)n repeats in the AR was performed in a Caucasian population by gene sequencing in fertile men (n=13), infertile men (n=64), boys conceived after ICSI (n=21), and boys conceived naturally (n=11). In the AZF...
Apolipoprotein B (APOB) plays a key role in lipoprotein metabolism and plasma lipid transport. It has been shown that about two-thirds of male mice heterozygous for ApoB were infertile. Moreover, a 3-codon deletion polymorphism (rs11279109) in the signal peptide region of the APOB gene has been shown to be a risk factor for infertility in Slovenian men, but its association with infertility in I...
