Begins with spermatogonia, which undergo mitosis to form primary spermatocytes.
Primary spermatocytes undergo meiosis to form secondary spermatocytes, which then develop into spermatids.
These spermatids differentiate into spermatozoa (sperm).
1. Spermatogonia (Spermatogonium)
2. Primary spermatocyte
