Chromosomal studies in infertile men with oligozoospermia & non-obstructive azoospermia.
BACKGROUND & OBJECTIVE Chromosomal anomalies have been postulated to be as one of the principal genetic factors in male infertility. Cytogenetic evaluation of men with severely compromised semen parameters reveals an increased incidence of chromosomal aberrations when compared with the normal population. The objective of this study was to determine the chromosomal constitution and sperm charact...
متن کاملY Chromosome Microdeletions in Infertile Men with Non-obstructive Azoospermia and Severe Oligozoospermia
BACKGROUND The purpose of the study was to investigate the frequencies and types of Y chromosome microdeletions in infertile men and to analyze the relationship between the levels of reproductive hormones and Y microdeletions. METHODS A total of 1,226 infertile men were screened for Y chromosome microdeletions using multiplex PCR assay. Karyotype analysis was performed on peripheral blood lym...
متن کاملCystic fibrosis mutation screening in CBAVD patients and men with obstructive azoospermia or severe oligozoospermia.
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...
متن کاملGenetic anomalies in patients with severe oligozoospermia and azoospermia in eastern Turkey: a prospective study.
Infertility is defined as the inability to conceive a child after one year of regular unprotected intercourse; it is a major health problem affecting about 10-15% of all couples. Infertility is due to a male factor in approximately 50% of cases. The human Y chromosome contains genes necessary for gonadal differentiation into a testis and genes for complete spermatogenesis. We examined the frequ...
متن کاملAssociation of Two Polymorphisms in H2B.W Gene with Azoospermia and Severe Oligozoospermia in An Iranian Population
Background During spermatogenesis, the H2B family, member W (H2B.W) gene, encodes a testis specific histone that is co-localized with telomeric sequences and has the potential role to mediate the sperm-specific chromatin remodeling. Previously H2B.W genetic variants were reported to be involved in susceptibility to spermatogenesis impairment. In the present study, two single nucleotide polymorp...
