Question

Spermatogenesis involves two major events. What is the second major event?

Options

• Metamorphosis of spermatids into mature spermatozoa (spermiogenesis)

• Meiosis I division

• Formation of secondary spermatocytes

• Mitotic division of spermatogonia

Answer 1

The two major events in spermatogenesis are: (1) Formation of spermatids from spermatogonia via meiosis, and (2) Metamorphosis (spermiogenesis) of spermatids into mature spermatozoa. Spermiogenesis is the structural differentiation process that transforms round, non-functional spermatids into functional, motile sperm cells.
