Gene copy number reduction in the azoospermia factor c (AZFc) region and its effect on total motile sperm count

Gene copy number alterations in the azoospermia-associated AZFc region and their effect on spermatogenic impairment.

The azoospermia factor c (AZFc) region in the long arm of human Y chromosome is characterized by massive palindromes. It harbors eight multi-copy gene families that are expressed exclusively or predominantly in testis. To assess systematically the role of the AZFc region and these eight gene families in spermatogenesis, we conducted a comprehensive molecular analysis (including Y chromosome hap...

The Influence of Sperm Morphology, Total Motile Sperm Count of Semen and the Number of Motile Sperm Inseminated in Sperm Samples on the Success of Intrauterine Insemination

BACKGROUND The present study aimed to analyze the prognostic value of sperm morphology , total motile sperm count (TMSC) and the number of motile sperm inseminated (NMSI) on the outcome of intrauterine insemination (IUI). MATERIALS AND METHODS This cross sectional study was carried out 445 women undergoing 820 IUI cycles. All of the patients underwent controlled ovarian hyper stimulation with...

Analysis of partial azoospermia factor c deletion and DAZ copy number in azoospermia and severe oligozoospermia.

Microdeletions of the azoospermia factor (AZF) regions in the Y chromosome are a well-known genetic cause of male infertility, resulting in impairment of spermatogenesis. However, the partial deletions of AZFc region related to spermatogenetic impairment are controversial. We investigated partial deletion of AZFc region and DAZ copy number in a population of Iranian infertile men and normozoosp...
