Evaluation of Protamine Level in Human Sperm Samples Using Chromomycin A3 and Aniline Blue Staining
Background: Current microscopic experimental methods cannot diagnose DNA damages present in spermatozoa .Therefore, some methods are needed to address the abnormality of the genetic material status on the sperm samples. As reported by many investigators aniline blue staining technique has been used for identifying sperm chromatin condensation. Also, chromomycin A3 is used for evaluation of the ...

Background Chromomycin A3 (CMA3) staining has been used to assess protamine deficiency. The aim of this study was to determine credibility of CMA3 along with semen parameters for assessment of fertility potential. MaterialsAndMethods Semen analysis and CMA3 staining were carried out on 234 fertile and 178 subfertile individuals. Semen analysis was assessed according to WHO criteria. Protamine d...

The biosynthesis of chromomycin A3 was investigated using 13C-labeled acetates, methionine and glucose, and 13C,18O-labeled acetate. 13C NMR spectral analysis demonstrated that: Aglycone assembly occurs by combining at least two polyketide chains; three of nine oxygen atoms of the aglycone originate from acetate precursor oxygen atoms; carbon methylations on the aromatic ring at C-7, on the chr...
full textEffect of Protamine Deficiency on Fertilization Outcome and Incidence of Sperm Premature Chromosomal Condensation Post ICSI
Purpose: After aneuploidy,sperm premature chromatin condensation (PCC) is the next most important cause of fertilization failure. Therefore the aim of this study is to evaluate the effect of sperm protamine deficiency on sperm PCC formation post ICSI. Materials and Methods: Cytogenetic analysis was carried out on unfertilized oocytes post ICSI and incidence of sperm PCC was evaluated. The resu...
