studied ejaculates from a man with a 40%
incidence of macrocephalic spermatozoa and found that
many of the abnormal spermatozoa were diploid.
Moreover, an increased risk of aneuploidy in spermatozoa
from men with constitutional chromosome
abnormalities was found by Mercier and Bresson
[36], Sprigss and Martin [37], and Rousseaux et al.
[27,28].
