| pubmed-article:3597739 | pubmed:abstractText | Spermatogenesis and meiotic chromosomal behaviour was analysed in a group of males aged 60-80 years. 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. | lld:pubmed |
