摘要
Human spermatozoa were studied with a nonradioactive in situ hybridization method. Using a chemically modified DNA probe and immunocytochemical reactions for visualization, it was possible to obtain hybridization signals in 31 of 32 semen samples. Positive hybridization reactions, depending on cell accessibility, varied from 40% to over 90% for the different samples. Using a chromosome 1‐specific DNA probe, disomy for this chromosome was found in 0.67% of all accessible sperm cells. Copyright © 1991 Wiley‐Liss, Inc.
