Spermatogenesis:
The process of production of sperm is called spermatogenesis and it occurs inside the seminiferous tubules which are lined by germinal epithelium.
A cell from germinal epithelium gets separated and goes into the following stages to form sperm
PRIMARY SPERMATOCYTES ----- SECONDARY SPERMATOCYTES ---- SPERMATIDS ---- SPERMS.
All the above the steps occurs inside the Seminiferous tubule.![enlightened enlightened](http://www.biology.lifeeasy.org/qa-plugin/wysiwyg-editor/plugins/smiley/images/lightbulb.gif)
