Abstract
Translocation of sex/autosome chromosomes is uncommon, but they have a stronger impact on fertility than autosome/autosome translocation. Y/autosome translocation is associated with azoospermia in 80% of cases. To our knowledge, there have been only eight cases reported of a balanced reciprocal (Y;16) translocation associated with male infertility.Here we report an infertile man with azoospermia who has a reciprocal translocation t(Y;16) (q12; p13.2). A 38-year-old Saudi medically free male presented with primary infertility and azoospermia for six years. He has a positive family history of male infertility. Physical examination was unremarkable. Investigations showed normal hormonal panel and azoospermia. He has a male karyotype with a reciprocal chromosome Y,16 translocation. Histopathology report of bilateral testicular sperm extraction (TESE) revealed most tubules show early maturation arrest and few show either Sertoli-cell only syndrome or are completely hyalinized and atrophic. This case illustrates a rare cause of non-obstructive azoospermia in a male with chromosome Y,16 translocation as a result of a meiotic arrest. Medical practitioners should be aware of the genetic abnormalities of male patients who present with primary infertility. Karyotyping has the capability to diagnose genetic abnormalities in this patient.

Abstract
Background Y chromosome microdeletions are usually de novo mutations, but in several cases, transmission from fertile fathers to infertile sons has been reported. Material/Methods We report 3 cases of infertile patients who inherited expanded Y chromosome microdeletions from their fathers, who carried b2/b3 subdeletion or duplication. The karyotype was analyzed using G-banding. High-throughput sequencing was used to detect AZF region microdeletions. Results Cytogenetic analysis showed a normal karyotype 46,XY in patient 1 (P1), patient 2 (P2), and their fathers (F1 and F2). Patient 3 (P3) and his father (F3) presented a karyotype of 46,XY,Yqh-. High-throughput sequencing for the AZF disclosed an identical b2/b3 subdeletion in the F1 and F2. P1 had an AZFc deletion that accounted for 3.5 Mb, and P2 had an AZFa+b+c microdeletion that accounted for 10.5 Mb. F3 had a b2/b3 duplication of 1.8Mb, but P3 had an AZFb+c deletion of 6.2 Mb. Conclusions Our findings suggest that b2/b3 partial deletion or duplication can lead to structural instability in the Y chromosome and be a risk factor of complete deletion of AZFc or more expanded deletion during transmission.

Abstract
Balanced translocations are known to be associated with infertility, spontaneous abortions and birth defects in mammals. Spermatocyte spreading and immunostaining were applied to detect meiotic prophase I progression, homologous chromosome pairing, synapsis and recombination in an azoospermic reciprocal translocation 46,X,t(Y;1)(p11.3;p31) carrier. Histological examination of testicular sections revealed a severely reduced number of germ cells with no spermatids or sperm in the carrier. A significant reduction in XY recombination was observed in the patient. The number of MLH1 foci on autosomes that are not involved in the translocation per cell was also significantly decreased in our patient as compared to the controls, which indicates an inter-chromosomal effect (ICE) of the translocation on recombination. An increase in leptotene (P<0.001) and zygotene (P<0.001) and a decrease in pachytene spermatocytes (P<0.001) were observed in the carrier when compared with the controls, indicating disturbed meiotic progression in the patient. Increased RAD51 foci during pachytene (P=0.02) in the spermatocytes of the patient were noted. A decreased expression of the genes (USP1, INSL5, LEPR and MSH4) critical for meiosis/spermatogenesis and located around the breakpoint region of chromosome 1 was observed in the 46,X,t(Y;1) carrier, which may further exacerbate the meiotic failure such as reduced recombination on autosomes and ultimately cause spermatogenesis arrest. In summary, we report a series of events that may have caused infertility in our 46,X,t(Y;1) carrier. To the best of our knowledge, this is the first report shedding light on how, possibly, a reciprocal translocation affects meiosis at the molecular level in azoospermia patients.

Abstract
Chromosomal defects are relatively frequent in infertile men however, translocations between the Y chromosome and autosomes are rare and less than 40 cases of Y-autosome translocation have been reported. In particular, only three individuals has been described with a Y;21 translocation, up to now. We report on an additional case of an infertile man in whom a Y;21 translocation was associated with the deletion of a large part of the Y chromosome long arm. Applying various techniques, including conventional cytogenetic procedures, fluorescence in situ hybridisation (FISH) analysis and array comparative genomic hybridization (array-CGH) studies, we identified a derivative chromosome originating from a fragment of the short arm of the chromosome Y translocated on the short arm of the 21 chromosome. The Y chromosome structural rearrangement resulted in the intactness of the entire short arm, including the sex-determining region Y (SRY) and the short stature homeobox (SHOX) loci, although translocated on the 21 chromosome, and the loss of a large part of the long arm of the Y chromosome, including azoospermia factor-a (AZFa), AZFb, AZFc and Yq heterochromatin regions. This is the first case in which a (Yp;21p) translocation has been ascertained using an array-CGH approach, thus reporting details of such a rearrangement at higher resolution.

FISH and array CGH characterization of de novo derivative Y chromosome (Yq duplication and partial Yp deletion) in an azoospermic male. Reprod Biomed Online 2015; 31:217-24.

Abstract
This study presents a 28-year-old infertile male who was referred to the cytogenetic laboratory for chromosomal analysis after 4 years of regular unprotected intercourse in whom non-obstructive azoospermia was revealed. Standard cytogenetic G-banding was performed on metaphase spreads and a de-novo karyotype 46,X,der(Y)(q11.22;p11.3) was identified. This analysis was followed by flourescence in-situ hybridization(FISH) and array comparative genomic hybridization (aCGH). Finally, the patient's karyotype was identified as 46,X,der(Y)(qter→q11.221::p11.31→qter).ish der(Y) (qter+,pter-,SHOX+,SRY+,Ycen+,DYZ3+;DYZ1+,qter+).arrYq11.221q12(14,448,863-59,288,511) x2, Yp11.32p11.31(104,062-266,388) x0. It is proposed that de-novo derivative monocentric Y chromosome with duplicated region Y qter→q11.221::p11.31→qter with partial deletion of Yp PAR1 region most probably can perturb the conjugation of sex chromosomes during first meiotic division of spermatogenic arrested differentiation (development).
