Dicentric 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...
متن کاملA male pseudohermaphrodite with a dicentric Y chromosome. Autoradiographic study.
A 13-year-old male pseudohermaphrodite (mixed gonadal dysgenesis, unilateral testicular differentiation) was found to be a chromosomal mosaic of the 45, X0/46, XY type, the Y chromosome being a symmetrical dicentric chromosome. Presumed ¥ chromosomes similar to this one have been observed before, but their identification was not supported by autoradiographic data. In the present study the ident...
متن کاملDicentric Y chromosome in mixed gonadal dysgenesis.
A 15-year-old girl was investigated because of ambiguous genitalia. Her chromosome studies showed a 45, X/45, Xdic(Yq) mosaicism. The identity of the dicentric Y chromosome was demonstrated by its typical fluorescent banding patterns. Histological evidence of mixed gonadal dysgenesis with intragonadal tumour was observed, confirming the occurrence of gonadoblastoma associated with mosaicism in ...
متن کاملY chromosome deletions in azoospermic men in India.
Genetic factors cause about 10% of male infertility. Azoospermia factors (AZFa, AZFb, AZFc) are considered to be the most important for spermatogenesis. We therefore made an attempt to evaluate the genetic cause of azoospermia, Y chromosome deletion in particular, in Indian men. We have analyzed a total of 570 men, including 340 azoospermic men and 230 normal control subjects. DNA samples were ...
متن کاملMultiplex PCR Screening of Y Chromosome Microdeletions in Azoospermic Patients
Objective To develop a multiplex PCR protocol for routine screening of microdeletions on the Y chromosome Methods Five multiplex sets were established and Y chromosome microdeletions screening were carried out in 26 azoospermic men who undertook ICSI and 30 azoospermic men who undertook testicular biopsy. Results In 56 azoospermic men, 5 patients were found with AZFc/DAZ microdeletions, 2 patie...
