Abstract
During the histological investigation of testicular biopsy of patients with chromosomal aberrations, it was observed that in some of these patients more of the primary spermatocytes were in metaphase I, in comparison with normal testicular biopsy where, according to our investigations, these cells are only seen occasionally. A possible explanation for this phenomenon, which was mainly observed in patients with autosomal chromosome aberrations, is given.
