Meiotic and radiation studies in four oligochiasmatic men.

Abstract
The meiotic findings in 4 oligochiasmatic males are described. Radiation studies on the somatic cells of 3 of them failed to provide evidence for a reduced facility to repair DNA which might account for the observed failure of chiasma formation at meiosis. The data support the idea that the low chiasma count condition in sterile men is of mixed etiology.
