Spermatogonia going through mitosis to form primary spermatocytes in Grasshopper testes. Spermatocytogenesis. At puberty, spermatogonia located along the walls of the seminiferous tubules within the testis will be initiated and start to divide mitotically, forming two types of A cells that contain an oval shaped nucleus with a nucleolus attached to the nuclear envelope; one is dark (Ad) and ...
The process of spermatogenesis.1. Primary spermatocyte 2. Secondary spermatocytes 3. Spermatids 4. Sperm . Spermiogenesis is the final stage of spermatogenesis, during which the spermatids develop into mature spermatozoa.
The process of spermatogenesis as the cells progress from primary spermatocytes, to secondary spermatocytes, to spermatids, to Sperm Cycle of the seminiferous epithelium of the testis Spermatocytogenesis is the male form of gametocytogenesis and results in the formation of spermatocytes possessing half the normal complement of genetic material.
Schematic diagram of Spermatocytogenesis. Spermatocytogenesis is the male form of gametocytogenesis and involves stem cells dividing to replace themselves and to produce a population of cells destined to become mature sperm.

As the primary support cell of the tubules, they are generally very large and amorphous, with individual cells stretching from the basal lamina to the lumen; their cytoplasm often completely surrounds the germline cells which they are responsible for nursing.
Each secondary spermatocyte creates two spermatids during meiosis II making four spermatids all together. These spermatids mature into spermatozoa, also called sperm cells. Spermatozoa are the male gametes for sexually reproducing organisms. In humans the process of spermatogenesis is approximately a sixty-four day process. 1. Primary ...
As a result of meiosis, each spermatid contains only half of the genetic material present in the original primary spermatocyte. Spermatids are connected by cytoplasmic material and have superfluous cytoplasmic material around their nuclei.
