摘要: The use of fluorescence in situ hybridization (FISH) on decondensed sperm heads has allowed to analyse the chromosome constitution spermatozoa different populations. In controls, mean incidence disomy (including all chromosomes) is about 6.7 per cent; diploidy increases with age, and some individuals may show a special tendency nondisjunction. Carriers numerical sex anomalies low disomies (2.54-7.69 cent), need screen ICSI candidates for these conditions be reconsidered. inversions produce from 0 54.3 cent abnormal sperm. Robertsonian translocations 3.4 36.0 sperm, carriers reciprocal 47.5 81.0 spermatozoa. However, usually more embryos than expected figures. This partly related interchromosomal effects induced by structural reorganizations. Males oligoasthenozoospermia, motility and/or high FSH concentrations frequent synaptic anomalies, resulting production aneuploid diploid Testicular extremely rates chromosomal abnormalities. risk recurrent abortion increased presence abnormalities
