Description Spermatozoa of rohu (Labeo rohita) were diluted in two cryodiluents and fine
structural changes were investigated. Damages were observed in head, mid-piece
and tail of about 51% spermatozoa immediately after dilution in one of the
cryodiluents. After 10 minutes of equilibration period, the frequency of damaged
sperms increased to 85%. The other diluent did not exhibit signif~cant structural
changes unlike the former one and nearly 60% sperms remained visibly intact even
after 10 minutes of equilibration time. The present investigation points out (1)
diluents inhibiting sperm motility alone need not always be ideal for a species and
(2) usefulness of ultrastructural images of fish sperms in determining the fertilizing
ability of milt and in preliminary screening and selection of cryodiluents for deepfreezing
programmes.
