High deletion frequency of the complete AZFa sequence in men with Sertoli-cell-only syndrome.
We have developed a rapid screening protocol for deletion analysis of the complete AZFa sequence (i.e. 792 kb) on the Y chromosome of patients with idiopathic Sertoli-cell-only (SCO) syndrome. This Y deletion was mapped earlier in proximal Yq11 and first found in the Y chromosome of the SCO patient JOLAR, now designated as the AZFa reference patient. We now show that similar AZFa deletions occu...
متن کاملAZFa deletions in Sertoli cell-only syndrome: a retrospective study.
Lack of data on the genotype-phenotype relationship in cases of AZF microdeletions is due to the limited number of histological investigations in human male infertility cases. We investigated the possibility of retrospective detection of Yq11 microdeletions by using DNA extracted from diagnostic testicular biopsies. We used histological criteria to select two series of material: 22 biopsies wit...
متن کاملPredictive Factors of Successful Microdissection Testicular Sperm Extraction in Patients with Presumed Sertoli Cell-Only Syndrome
Background To evaluate predictive factors of successful microdissection-testicular sperm extraction (MD-TESE) in patients with presumed Sertoli cell-only syndrome (SCOS). MaterialsAndMethods In this retrospective analysis, 874 men with non-obstructive azoospermia (NOA), among whom 148 individuals with diagnosis of SCOS in prior biopsy, underwent MD-TESE at Department of Andrology, Royan Institu...
متن کاملSertoli cell-only syndrome
Sertoli cell-only syndrome is defined by the complete absence of germ cells in testicular tissues and always results in male infertility. Germ cells give rise to next stages of spermatogenesis which is the process of sperm formation. They are normally attached to Sertoli cells forming together so called seminiferous tubules which form testicular tissue. If there are only Sertoli cells, then n...
