Y-chromosome microdeletions in nonobstructive azoospermia and severe oligozoospermia
The aim of the present work was to present the outcomes of the patients with Y-chromosome microdeletions treated by intracytoplasmic sperm injection (ICSI), either using fresh (TESE) or frozen-thawed (TESE-C) testicular sperm and ejaculated sperm (EJAC). The originality of this work resides in the comparisons between the different types of Y-microdeletions (AZFa, AZFb, and AZFc) and treatments,...
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 کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولfrequency of y chromosome microdeletions among iranian infertile men with azoospermia and severe oligozoospermia: a meta-analysis
background: while multiple factors can contribute to male infertility, genetic factors, such as chromosomal disorders or y-chromosome microdeletion, are responsible for about 10% of male infertility. considering the role of y-chromosome microdeletions in men with oligozoospermia who volunteer for in vitro fertilization (ivf), the prevalence of such microdeletions in each particular community ne...
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...
