Question

What is the term used to describe the process by which spermatids metamorphose into mature spermatozoa?

Options

• Mitosis

• Spermiogenesis

• Spermatogenesis

• Meiosis

Answer 1

Spermiogenesis is the process of metamorphosis (structural differentiation) by which round, non-functional spermatids are transformed into mature, functional spermatozoa. This is the second major event in spermatogenesis, following the formation of spermatids from spermatogonia via meiosis. Spermiogenesis involves the development of the flagellum, acrosome, and other specialized structures necessary for sperm function.
