Meiotic studies in an azoospermic human translocation (Y;1) carrier.
A reciprocal translocation between the long arm of the Y chromosome and the long arm of chromosome 1 was observed in an infertile man with non-obstructive azoospermia. The study was performed using a combination of techniques: immunocytogenetic analysis, which allows the detection of synaptonemal complexes (SCs) and recombination sites (MLH1) simultaneously, and fluorescence in-situ hybridizati...
متن کاملAbnormal synapses and recombination in an azoospermic male carrier of a reciprocal translocation t(1;21).
OBJECTIVE To study the meiotic abnormalities during prophase I in an azoospermic man with t(1;21) reciprocal translocation. DESIGN Analysis of synapses, recombination, and transcription inactivation in a testicular biopsy sample. SETTING Research laboratory. PATIENT(S) One azoospermic patient with t(1;21) and five men with normal spermatogenesis. INTERVENTION(S) Immunostaining for SCP3,...
متن کاملA complex balanced rearrangement involving four chromosomes in an azoospermic man.
A complex chromosomal rearrangement involving chromosomes 1, 5, 10, and 12 is described. The patient was an infertile, phenotypically normal male. Cytogenetic analyses of his parents showed that the complex translocation arose de novo. Testicular histology showed spermatogenic arrest.
متن کامل45,XY,der(13;14)(q10;q10) in an azoospermic man with hypogonadotrophic hypogonadism.
Turkey. We write to you about a case of 45,XY,der(13; 14)(q10;q10) in an azoospermic man as a result of hypo-gonadotrophic hypogonadism. The most frequent form of Robertsonian transloca-tion is between chromosomes 13 and 14 [1]. It is reported to be a cause of male infertility [2–4]. The frequency of Robertsonian translocation among infertile men has been reported to be 1%, which is higher than...
متن کاملDicentric Y chromosome in an azoospermic male.
We describe a 28 year old male with a pseudodicentric Y chromosome who suffered from azoospermia attributed to maturation arrest of the primary spermatocyte, as diagnosed by testicular biopsy. Chromosome analysis, using G, Q and C banding techniques, revealed an abnormal karyotype of 45,X[7]/46,X,psu dic (Y)(pter-->q11.2::q11.2-->pter)[33]. Polymerase chain reaction (PCR) DNA analysis did not d...
