Decreased spermatogenesis was found in most of these aged men although individual differences existed. Chromosomal analysis of cells undergoing diakinesis showed significantly lower chiasma frequency in elderly men, compared with a group of younger control males and also with infertile males. © 1987 IRL Press Limited.AgeingChromosomal analysisMeiosisSpermatogenesis
