![]() The Spermatogenic cycle is the time taken for the same stage of spermatogenesis to appear in the same segment of the seminiferous tubule.It involves the removal of glycoproteins and cholesterol and activating signalling pathways. Sperm capacitation is the final step to allow for fertilisation.Spermiogenesis is the transition of spermatids into mature sperm cells, with spermiation ending with mobile sperm.Spermatogonia also produce type A spermatogonia which are recycled to replenish the spermatogonia supply. Spermatogenesis involves the following transitions: primordial germ cells -> spermatogonia -> type B spermatogonia -> primary spermatocyte -> secondary spermatocyte -> spermatids.Gametogenesis is the production of sex cells (gametes) through meiosis. ![]()
