WebSpermatogenesis is the process by which the four spermatozoa are produced in the seminiferous tubules present in the testes. The primary spermatocyte is converted to two secondary spermatocytes through mitotic division and this secondary spermatocyte gives rise to two spermatids through the process of meiosis II. WebAbstract A series of 10 young sterile men with acephalic spermatozoa or abnormal head-mid-piece attachments is presented. Nine of these patients had 75-100% spermatozoa with minute cephalic ends and 0-25% abnormal head-middle piece attachments. Loose heads ranged between 0-35 for each 100 spermatozoa and normal forms were rare. hri summer clearance
