We evaluate the association between genetic polymorphisms of XRCC5 VNTR, XRCC6 -61C>G, and XRCC7 6721G>T with male infertility susceptibility. A total of 392 men including 178 infertile males (102 idiopathic azoospermia and 76 severe oligozoospermia) and 214 healthy controls were recruited. XRCC6 -61C>G and XRCC7 6721G>T genotyping was performed by PCR-RFLP whereas XRCC5 VNTR was performed by P...
BACKGROUND Randomized controlled trials comparing different vasectomy occlusion techniques are lacking. Thus, this multicenter randomized trial was conducted to compare the probability of the success of ligation and excision vasectomy with, versus without, fascial interposition (i.e. placing a layer of the vas sheath between two cut ends of the vas). METHODS The trial was conducted between De...
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...
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...
Our previous research suggested that an integrated analysis of microRNA (miRNA) and messenger RNA (mRNA) expression is helpful to explore miRNA-mRNA interactions and to uncover the molecular mechanisms of male infertility. In this study, microarrays were used to compare the differences in the miRNA and mRNA expression profiles in the testicular tissues of severe oligozoospermia (SO) patients wi...
Development in ART has been remarkable in the last decades. Several medical conditions affecting the male fertility status are now treated by ART, especially by the combination of in vitro fertilization and intracytoplasmic sperm injection. ICSI is now the treatment of choice of most untreatable causes of male infertility, including immunologic infertility, severe oligozoospermia and azoospermi...
