Structural abnormalities include various types of translocations, inversions, deletions,
duplications and isochromosomes. Structural abnormalities of the Y chromosome are …

BACKGROUND Cytogenetically detectable aberrations of the Y chromosome, such as
isodicentrics, rings or translocations are sometimes associated with male non-obstructive …

Structural rearrangement in the Y chromosome is closely involved in spermatogenesis.
However, several Y chromosome variants may have no deleterious effects on male …

Objective: To determine the prevalence of microdeletions of the long arm of chromosome Y
within the AZFa, AZFb, and AZFc subregions in patients with idiopathic azoospermia, and …

BACKGROUND: Partial deletions of the AZFc region of the Y chromosome were reported to
be a significant risk factor for oligo-/azoospermia. In this study, we assessed the occurrence …

We describe three cases in which we used fluorescence in situ hybridization (FISH),
polymerase chain reaction (PCR) and comparative genomic hybridization (CGH) to …

A mosaic karyotype consisting of a 45, X cell line and a second cell line containing a normal
or an abnormal Y chromosome is relatively common and is associated with a wide spectrum …

Background Structural abnormalities as well as minor variations of the Y chromosome may
cause disorders of sex differentiation or, more frequently, azoospermia. This study aimed to …

Cytogenetic and molecular deletion analyses of azoospermic and oligozoospermic males
have suggested the existence of AZoospermia Factor (s)(AZF) residing in deletion intervals …

Aim To review the accumulated 30 patients with different area of Y chromosome
microdeletions, focusing on their correlation with the clinical and pathological findings …
