#spermatogenesis
- Androcyte — An immature young male germ cell (also known as a spermatid) resulting from the meiotic division of secondary spermatocytes. In the context of structural spermatogenesis, the androcyte undergoes a complex phase of cellular differentiation and metamorphosis (spermiogenesis), ultimately transforming into a mature spermatozoon capable of fertilization.
- Androgonium — A primordial male mother cell (found in certain algae, fungi, and lower plants) which, through successive mitotic or meiotic divisions, gives rise to androgametes or spermatogenous cells inside an androgametangium. This initial cellular structure is fundamental for initiating male reproductive dynamics in cryptogamic organisms.
