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. The stem cells involved are called spermatogonia and are a specific type of stem cell known as gametogonia .
Spermatocytogenesis is the male form of gametocytogenesis and results in the formation of spermatocytes possessing half the normal complement of genetic material. In spermatocytogenesis, a diploid spermatogonium , which resides in the basal compartment of the seminiferous tubules, divides mitotically, producing two diploid intermediate cells ...
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 ...
Cross section of the epithelium of a seminiferous tubule showing various stages of spermatocyte development Scheme showing analogies in the process of maturation of the ovum and the development of the spermatids (young spermatozoa).
A spermatogonium (plural: spermatogonia) is an undifferentiated male germ cell.Spermatogonia undergo spermatogenesis to form mature spermatozoa in the seminiferous tubules of the testicles.
