The primary spermatocytes within the adluminal compartment will continue on to Meiosis I and divide into two daughters cells, known as secondary spermatocytes, a process which takes 24 days to complete. Each secondary spermatocyte will form two spermatids after Meiosis II.. Although spermatocytes that divide mitotically and meiotically are sensitive to radiation and cancer, spermatogonial stem. Covering the head of the sperm is a cap known as the acrosome, which contains enzymes that help sperm to enter an egg. Only one sperm fertilizes each egg, even though ,, to ,, sperm are contained in an average pmr21.info egg and sperm produced has slightly different genetic information carried in the chromosomes; this accounts for the differences and similarities.
