SPERMEIOGENESIS / SPERMETOLEOSIS
It is the gradual differentiation of a stationary rounded and undifferentiated spermatid into an active and motile sperm.
The spermatids formed as a result of maturation divisions are typical undifferentiated animal cells containing mitochondira, golgi body and centriole but with a haploid set of chromosomes.
In spermeiogenesis following changes take place -
(i) Formation of acrosome
Formation of Acrosome
(ii) Formation of Perforatorium
A rounded small pit present below the nucleus, in this part G actin and Ca++ ions are present. This spaces is called perforatorium space.
(iii) Nuclear changes
(iv) Tail
(v) Formation of mitochondrial spiral and middle piece
(vi) Changes in the cytoplasm
