Y 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 کاملChromosomal 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 کاملIn cryptozoospermia or severe oligozoospermia is sperm freezing useful?
BACKGROUND Intracytoplasmic Sperm Injection (ICSI) is an Assisted Reproduction Technique (ART) which offers the chance to conceive to patients presenting very low sperm counts (cryptozoospermia/severe oligozoospermia). Sperm freezing before the oocyte pick-up, can prevent from a lack of spermatozoa on the day of the ICSI. It can avoid the cancellation of the ICSI or the use of TESE (Testicular ...
متن کاملI-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...
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...
