Abstract
Sections of ejaculated spermatozoa from rabbits with known fertility w ere Observed by transmission electron microscopy. Acrosome defects, od d head shapes, the presence of spermatids and the decondensation of sp erm nuclei were recorded. The fertility negatively correlated with the number of acrosomal defects, while litter size was negatively related to nuclear decompaction. Sperm nuclear decondensation was present in all ejaculates. Its frequency was correlated with that of spermatids i n ejaculates.
