The primordial germ cell in the embryo undergoes mitosis to produce a spermatogonial stem cell.
<span>The spermatogonial stem cell undergoes mitosis. The new cells could either be stem cells or spermatogonium cells. </span>
<span>The spermatogonium undergoes mitosis to generate a primary spermatocyte. </span>
<span>*** Up until this point, all cells are diploid **** </span>
<span>The primary spermatocyte (diploid) undergoes MEIOSIS I to generate TWO haploid secondary spermatocytes. </span>
<span>Each secondary spermatocyte undergoes MEIOSIS II to generate a total of FOUR early spermatid. </span>
<span>The spermatid mature in the seminiferous tubule, and once they are completely mature they are released into the lumen. </span>
<span>Now called sperm cells, they pass into the epididymis, where they are stored until time to be released during ejaculation. </span> Hope this helped
