Synapsis and synaptic adjustment in an infertile human male heterozygous for a pericentric inversion in chromosome 1

Abstract
Synapsis and “synaptic adjustment” were analyzed, using electron microscopy in silver stained surface microspreads of inversion-bearing spermatocytes, in an infertile human male with an inherited pericentric inversion in chromosome 1. Possible reasons for his infertility are discussed.
