Sperm morphology in subfertile carriers of autosomal translocations.
Sperm morphology of nine translocation carriers was compared with that of subfertile controls with a normal karyotype to determine whether there was a specific morphologic pattern in translocation carriers. The two groups were matched for age, sperm concentration, sperm motility, and presence or absence of a varicocele testis. No specific abnormality of sperm morphology was found among the translocation carriers. No significant difference in either the percentage of abnormal sperm or the morphologic pattern of sperm was observed between the two groups. It was concluded that structural chromosomal aberrations have no relation to sperm morphology.
