reduced sperm quantity and motility are primary causes of infertility in men. before researchers showed that, nsun7 gene has roles in sperm motility of mouse, that creation defect in this gene is cause infertility. this gene in human located in chromosome 4, with 12 exons and a hot spot exon (exon7). our aim is study of the mutations of the exon7 in the normospermic and asthenoteratospermic men...

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 ...

Purpose: To evaluate the current literature on the varicocele treatment and impact on fertility. Materials and Methods: Pertinent articles were identified through PubMed search on varicocele repair and male infertility. Discussion: The proposed mechanisms of how varicocele results in impaired spermatogenesis and infertility include an altered or impaired testicular blood flow, increased scrotal...

BACKGROUND The unfulfilled desire of millions of infertile couples worldwide to have their own biological children results in emotional distress. This study evaluated the emotional reactions of couples attending a combined infertility clinic in Kuwait and successful clients' perception of nurses. METHODS Quantitative and qualitative methods were used. The first phase was by structured intervi...

in some traditional societies including iran, birth giving is an element of women’s identity and status, also having a child is looked as a source of women’s power in the family and society. therefore infertility typically can be considered as womanly problem. consequently infertile women face more family and social problems than infertile men. this study is to examine the conditions of these w...

Sex hormone binding globulin (SHBG) is involved in delivering sex hormones to target tissues. We investigated the association between the (TAAAA)n repeat polymorphism, and Asp327Asn polymorphism in the SHBG gene with semen quality and idiopathic male infertility. We studied 168 men with idiopathic infertility [oligoasthenoteratozoospermia (OAT)] and equal number of age-matched normal controls. ...

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...

Protamine (PRM) plays important roles in the packaging of DNA within the sperm nucleus. To investigate the role of PRM1/2 and transition protein 1 (TNP1) polymorphisms in male infertility, 636 infertile men and 442 healthy individuals were recruited into this case-controlled study of the Chinese Han population, using MassARRAY technology to analyze genotypes. Our analysis showed that there were...

The reported effects of the glutathione S-transferase (GSTs) genes (GSTM1, GSTT1, and GSTP1) on male factor infertility have been inconsistent and even contradictory. Here, we conducted a case-control study to investigate the association between functionally important polymorphisms in GST genes and idiopathic male infertility. The study group consisted of 361 men with idiopathic azoospermia, 11...

BACKGROUND Ubiquitin, a house-keeping protein that marks other proteins for proteasomal degradation, tags defective sperm during epididymal passage. To establish ubiquitin as a biomarker of human infertility, the present study examines the relationships between sperm ubiquitin content and clinical semen parameters among men from an infertility clinic population with varied aetiologies. METHOD...
