Each testis is divided into approximately 250 lobules by fibrous septa that extend inward from the [[tunica albuginea]], the dense connective tissue capsule surrounding the testis.<br /> <br /> === Structure ===<br /> The lobules of the testis are conical in shape, with their bases directed towards the [[tunica albuginea]] and their apices converging towards the [[mediastinum testis]]. Each lobule contains one to four highly coiled [[seminiferous tubules]], which are the site of [[sperm]] production. The seminiferous tubules are lined with a specialized epithelium that includes [[Sertoli cells]] and [[spermatogenic cells]].<br /> <br /> === Function ===<br /> The primary function of the lobules of the testis is to facilitate the production of sperm. The [[seminiferous tubules]] within each lobule are the site of [[spermatogenesis]], the process by which [[spermatogonia]] develop into mature [[spermatozoa]]. The [[Sertoli cells]] within the tubules provide structural and nutritional support to the developing sperm cells.<br /> <br /> === Blood Supply ===<br /> The blood supply to the lobules of the testis is provided by the [[testicular artery]], which branches from the [[abdominal aorta]]. The [[testicular veins]] drain the blood from the testis and form the [[pampiniform plexus]], which helps in the regulation of testicular temperature.<br /> <br /> === Clinical Significance ===<br /> Disorders of the lobules of the testis can lead to impaired [[spermatogenesis]] and [[infertility]]. Conditions such as [[varicocele]], [[orchitis]], and [[testicular torsion]] can affect the function of the lobules and the overall health of the testis.<br /> <br /> === See Also ===<br /> * [[Testis]]<br /> * [[Spermatogenesis]]<br /> * [[Seminiferous tubules]]<br /> * [[Sertoli cells]]<br /> * [[Leydig cells]]<br /> * [[Tunica albuginea]]<br /> * [[Mediastinum testis]]<br /> <br /> [[Category:Male reproductive system]]<br /> [[Category:Anatomy]]<br /> [[Category:Histology]]<br /> <br /> {{Anatomy-stub}}</div>
