Mosaicism for 45,X cell line may accentuate the severity of spermatogenic defects in men with AZFc deletion.
PWS or may have had five of the following characteristics? Floppiness at birth. Initial failure to thrive or diYculty in sucking. The development of severe overeating and rapid weight gain in early childhood. Obesity or the need for weight control. Problems with sexual development (for example, undescended testes, delayed periods). Some learning disability (mental handicap). Small hands and fee...
متن کاملAssociation of Spermatogenic Failure with the b2/b3 Partial AZFc Deletion
Infertility affects around 1 in 10 men and in most cases the cause is unknown. The Y chromosome plays an important role in spermatogenesis and specific deletions of this chromosome, the AZF deletions, are associated with spermatogenic failure. Recently partial AZF deletions have been described but their association with spermatogenic failure is unclear. Here we screened a total of 339 men with ...
متن کاملMeiotic anomalies in infertile men with severe spermatogenic defects.
BACKGROUND This study was aimed at evaluating the rate of pairing failure in pachytene spermatocytes of patients presenting either an obstructive (O) or a non-obstructive (NO) infertility. METHODS Forty-one patients and 13 controls underwent testicular biopsy. Among the patients, 19 had an O infertility and 22 a NO infertility. Preparations of all patients and controls were Giemsa-stained, an...

Additional genomic duplications in AZFc underlie the b2/b3 deletion-associated risk of spermatogenic impairment in Han Chinese population.
The azoospermia factor c (AZFc) region on the Y chromosome is a genetically dynamic locus in the human genome. Numerous genomic rearrangements, including deletion, duplication and inversion, have been identified in AZFc. The complete deletion of AZFc can cause spermatogenic impairment. However, the roles of partial AZFc deletions (e.g. b2/b3 deletion) in spermatogenesis are controversial and va...
