<span>This would be the order of types of cell in producing sperm (spermatogenesis):</span>
<span>1. </span>Spermatogonium A
<span>2. </span>Spermatogonium B
<span>3. </span>Primary spermatocyte
<span>4. </span>Secondary spermatocyte
<span>5. </span>Spermatid
<span>6. </span>Sperm cell (spermatozoon)
The process from<span> the formation of spermatogonium up to and including the secondary spermatocyte is called </span>spermatocytogenesis.
The continuing process which includes maturation of the sperm cell, from the spermatid phase to the mature sperm cell is called spermiogenesis.
