A Comparative Study of AZF Deletions and TSPY Gene Variation in Czech and Indian Infertile Men
The human Y chromosome harbours genes that are essential for spermatogenesis. Most of these genes lie in the male-specific region (MSY) of Y chromosome. Microdeletions of AZF within the MSY have been reported in infertile men. Widely different frequencies of such deletions (0-55%) have been reported from different populations. TSPY is another gene located in the MSY region that plays a signific...
متن کاملGr/gr deletions on Y-chromosome correlate with male infertility: an original study, meta-analyses, and trial sequential analyses.
We analyzed the AZFc region of the Y-chromosome for complete (b2/b4) and distinct partial deletions (gr/gr, b1/b3, b2/b3) in 822 infertile and 225 proven fertile men. We observed complete AZFc deletions in 0.97% and partial deletions in 6.20% of the cases. Among partial deletions, the frequency of gr/gr deletions was the highest (5.84%). The comparison of partial deletion data between cases and...
متن کاملAZF deletions in infertile men from the Republic of Macedonia.
Y chromosome deletions in the three azoospermia factor (AZF) regions constitute the most common genetic cause of spermatogenic failure. The aim of this study was to estimate the length and boundaries of the AZF deletions and to correlate the AZF deletions with the sperm concentrations, testicular histology, Y haplogroups and the ethnic origin of the men with deletions. PCR analysis of STS loci ...
متن کاملHuman chromosome deletions in Yq11, AZF candidate genes and male infertility: history and update.
Human chromosome deletions in Yq11 seem to occur frequently as de novo mutation events in men with idiopathic azoospermia or severe oligozoospermia. However, the molecular extensions of these deletions are variable. They can be large and therefore visible under the microscope or small, not visible under the microscope, and containing the deletion of one or more DNA loci recently mapped in an ap...
