Abstract
Four cases of low chiasma frequency have been detected using a technique to study meiosis in semen. Three of the patients showed desynapsis and fragmentation of the bivalents. In the fourth case, desynapsis was probably due to an abnormal despiralization of the bivalents. None of the patients had a spermatogenic arrest. Banding studies did not permit to identify the chromosomal fragments. The incidence of oligochiasmatic males in our semen and testicular biopsy series is about 2.5%. The advantages of the method are discussed. Copyright © 1978, Wiley Blackwell. All rights reserved
