    Kleiman S, Lagziel A, Yogev L, Botchan A, Paz G, Yavetz H. Expression of CDY1 may identify complete spermatogenesis. Fertil Steril. 2001;75:166-73 pubmed
    ..Our preliminary results suggest that CDY1-minor expression might increase the prospect for complete spermatogenesis, while RBM and DAZ expression can only be indicative of the presence of germinal cells. ..

    ..Referring men with complete AZFb/b-c microdeletions to testicular sperm extraction/ICSI programs should be revaluated. ..

    ..It is suggested that this difference might be due to the specific highly abnormal histological morphometric parameters in KS specimens. ..

    ..Our results suggest that HGCL is not essential for the chromosomal events of meiosis but might be involved in later aspects of spermatogenesis. ..

    ..However, in consideration of the high levels of identity between CDY1 and CDY2 (98% at the protein level), the delayed up-regulation of CDY1 transcripts could be attributable to temporal changes in dosage requirements. ..

    ..The findings contribute to the search and selection of the most valuable gene markers potentially useful as additional tools for predicting complete spermatogenesis by multiplex expression analysis. ..

    ..3%. Assessing the expression of both CDY1 and BOULE by qualitative RT-PCR is a sensitive and feasible test for predicting the presence of sperm cells in testicular tissue and may serve as a predictive tool if repeated TESE is required. ..
