    Details are given of a balanced 21q22q Robertsonian translocation ascertained through infertility in a phenotypically normal male. Chromosome analyses on the proband and his parents showed that the translocation arose as a new mutation. The patient was oligospermic and had a high frequency of morphological abnormalities in his spermatozoa. Meiotic investigations showed a chain trivalent in all primary spermatocytes examined at diakinesis/metaphase I. The testicular histology was normal.
