it is now agreed that 10-25% of infertile men with azoospermia have submicroscopic deletions of the y chromosome long ann (yq), consistent with the proposed location of the azoospermia locus (azf) in yq 11.23. however, it is not known whether yq microdeletions are unique to men with azoospermia or whether they are also observed in infertile men with less severe defects of spermatogenesis (oligo...
Congenital bilateral absence of the vas deferens (CBAVD) found in otherwise healthy infertile males, is associated with a high incidence of mutated cystic fibrosis transmembrane conductance regulator (CFTR) alleles, and is considered a genital form of cystic fibrosis (CF). The CF gene may also be involved in the aetiology of male infertility in cases other than CBAVD. The present study was unde...
BACKGROUND The meiotic program initiation pathway genes (CYP26B1, NANOS1 and STRA8) have been proposed to play key roles in spermatogenesis. OBJECTIVE To elucidate the exact role of the genetic variants of the meiosis initiation genes in spermatogenesis, we genotyped the potential functional genetic variants of CYP26B1, NANOS1 and STRA8 genes, and evaluated their effects on spermatogenesis in...
OBJECTIVE The main objective of this study was to assess semen characteristics of patients with testicular cancer before cryopreservation and after thawing, to evaluate the consequences of this technique on sperm quality in patients with testicular cancer. METHODS Five hundred eighty-nine samples from 543 patients with testicular cancer were cryopreserved between 1995 and 2015, one aliquot pe...
Introduction: The CGA gene encodes alpha subunit of glycoprotein hormones that are involved in the fertility process. The aim of this study was to evaluate the relationship between glycoprotein hormones, alpha polypeptide (CGA) rs6631A> T gene polymorphism with the risk of men with azoospermia or severe oligozoospermia. Methods: This study was conducted in a case-control study on 200 bloo...
Coenzyme Q10 and oxidative stress markers in seminal plasma of Iraqi patients with male infertility.
OBJECTIVE To evaluate seminal plasma coenzyme Q10 (CoQ10) levels and oxidative stress in patients with different types of male infertility. METHODS A case-control study was carried out in the Department of Chemistry and Biochemistry, College of Medicine, Al-Nahrain University, Baghdad, Iraq from the period of November 2004 to July 2006. Sixty patients with male infertility were recruited from...
