Reproductive Failure and Pericentric Inversion in Man

Abstract
Pachytene analysis was carried out on an infertile man heterozygous for a pericentric inversion of chromosome 6. The synaptic behavior of the bivalent 6 inversion was analyzed using electron microscopy in silver stained surface microspread of the inversion-bearing spermatocytes. Possible mechanisms of the sterilizing effect caused by the autosomal inversion are discussed.
