Spermatogonia were present near the basal membrane. Stage 4: (d) this stage was identified by the presence of step 4 spermatids. In the second row, leptotene primary spermatocytes were present. Step 10 spermatids were observed moving towards the luminal border. Between the third and fourth germ cell layers, pachytene spermatocytes were observed.

Spermatogenesis is the process by which male primary sperm cells undergo meiosis and produce a number of cells calls spermatogonia, from which the primary spermatocytes are derived. Each primary spermatocyte divides into two secondary spermatocytes and each secondary spermatocyte into two spermatids or young spermatozoa.

Spermatogenesis: All spermatogonia are divided by meiosis, producing sperms all the times. Oogenesis: Some of the oogonia divide during the production of eggs, one at a time. Introduction. The rat has long been an important model of mammalian spermatogenesis, and the histological process of rat male germ cell differentiation is well understood [].An overview of the differentiation program is shown in Fig 1A.Spermatogonial stem cells (SSCs) form the basis for lifelong sperm production as they can both self-renew and differentiate into all germ cell types. Given below are the differences between spermatogenesis and spermiogenesis. Select the incorrect option. View Solution. Q4. Match the correct explanation of the terms. 1. Release of sperm finally into the cavity of seminiferous tubules A.Spermatogenesis: 2. Transformation of spermatids into spermatozoa Spermatogenesis is the production of sperm from the primordial germ cells within the male reproductive organs, the testes. The process of spermatogenesis occurs in the epithelium of the seminiferous tubules, with the spermatogonia and the spermatozoa at the lumen of the border of the tubule. What is the difference between spermatogonia and primary spermatocytes? Each spermatogonia is diploid containing 46 chromosomes. Some spermatogonia undergo changes as they grow and increase in size by accumulating and assimilating the nourishing materials and are called primary spermatocytes which periodically undergo meiosis and others that are left behind are termed as spermatogonia. uQA4X.
