Q.What is spermiation?

Spermiation is the release of fully formed sperm from Sertoli cells into the tubule lumen — the final step of spermatogenesis.

During spermatogenesis, round spermatids undergo spermiogenesis (a series of structural changes — acrosome formation, condensation of the nucleus, development of the flagellum, loss of most cytoplasm) to become elongated, mature spermatozoa while still embedded in the Sertoli cells that nourish them. Spermiation is the final event of this process, in which the mature spermatozoa are released from their attachment to the Sertoli cells into the lumen of the seminiferous tubules, from where they are …
