Spermatogenesis Mechanism
Captions available
The idea
Spermatogenesis produces sperm through mitotic division followed by meiosis, yielding four genetically distinct, motile sperm cells from each starting cell.
In practice
Meiotic division halves the chromosome number, producing haploid sperm suited to fuse with an egg.
Where people slip
All four meiotic products mature into sperm here, unlike oogenesis, where three are discarded as polar bodies.
