[ 1 ] - I-6: Azoospermia Factor in Male Infertility

Background The human Y chromosome is essential for human sex determination and male germ cell development and maintenance. In 1996, Vogt et al. identified three recurrently deleted regions in Yq11 termed the azoospermia factor (AZF). The AZF region is subdivided into three non-overlapping sub-regions called AZFa, AZFb and AZFc and microdeletion in these regions is the most important etiology of...

[ 2 ] - O-35: Assessment of Genetic Variations of DPY19L2 in Total Globozoospermic Patients Referring to Royan Institute

Background Globozoospermia is a rare but severe teratozoospermia disorder which causes male infertility. Total globozoospermia is diagnosed by the presence of 100% roundheaded spermatozoa lacking an acrosome in semen analysis. Recent studies have shown that in large majority of globozoospermic patients, deletion of a 200 kb segment including the DPY19L2 gene occurs. Among all the genes in this ...

[ 3 ] - O-36: Evaluation of Genetic Variations in Intron 4 and Exon 5 of RABL2B Gene in Infertile Men with Oligoasthenoteratospermia and Immotile Short Tail Sperm Defects

Background One of the main causes of male infertility is defect in structure and function of sperm cells. Infertile men with oligoasthenoteratospermia (OAT) defect, have sperms with abnormalities in count, motility and morphology. Patients with immotile short tail sperm (ISTS) disorder have immotile short-tailed sperm with disorganized axonem, and a significant decrease in sperm counts. Numerou...

[ 4 ] - P-13: The Expression of SOX3 Gene in Human Sertoli Cells of Azoospermic Patient

Background Sertoli cells located in seminiferous tubular basement membrane and surrounds different types of germ cell and they were only somatic cell type that directly contacts germ cells. These cells have Several role like support activities, nutrition of germ cells.During spermatogenesis, expression of SOX3 is necessary for differentiation of spermatogonia A. SOX3 is a transcription factor, ...

[ 5 ] - P-61: Effect of 830 nm Diode LASER Irradiation on Human Sperm Motility

Background Sperm motility is known as an effective parameter in male fertility and it depends on energy consumption. Low level LASER irradiation could increases energy supply to the cell by producing of adenosine triphosphate (ATP). The purpose of this study is to evaluate how the low level LASER irradiation affects the human sperm motility. MaterialsAndMethods Fresh human semen specimens of as...

[ 6 ] - P-116: Absence of JMJD1A, A Testis- Specific Histone Demethylase, in Tissue Samples of TESE Negative Men

Background During mammalian spermatogenesis unique and dynamic epigenetic events occur leading to chromatin condensation. Through these events, histone demethylases such as JMJD1A play important roles in compaction of sperm chromatin, due to regulation of histone methylation dynamics and alteration of chromatin structure. As �histone methylation� is one of the best-characterized modifications i...

[ 7 ] - P-118: Triplet Nucleotide Repeats Expansion (CAG and GGN) of Androgen Receptor Gene in Infertile Patients with Abnormal Spermogram

Background s:648:"The infertility has recently been estimated to affect approximately 9% of couples worldwide. Androgens and a functional androgen receptor (AR) are essential for normal development of the male gender, and for maintenance of spermatogenesis throughout the life. Two polymorphic trinucleotide repeats, CAG and GGN, encoding for the amino acids glutamine and glycine, respectively ar...

[ 8 ] - P-119: Survey of Genetic Alterations in Exon1 of Androgen Receptor Gene in Azoospermic Patients

Background Androgen receptor (AR) mediates androgen actions such as initiation and promotion of spermatogenesis and growth of accessory sex organs. There are two trinucleotide polymorphisms (CAG and GGN repeats) in exon1 of AR gene that are vary in length in population. The CAG and GGN repeats association with infertility is still unknown and this study is planned to assess the distribution of ...

[ 9 ] - P-133: Investigation of Genetic Variations in Exon 6 of AKAP4 Gene in Infertile Men with Immotile Short Tail Sperm

Background The immotile short tail sperm (ISTS) defect is one of the disorders that cause male infertility. Men with this condition have immotile short-tail sperm with structural defects in the fibrous sheath(FS). A Kinase Anchoring Protein 4 (AKAP4) is one of the most abundant proteins in the fibrous sheathof sperm flagella and provides scaffold for the correct assembly of FS.Since exon 6 of A...
