A. Each testicular lobule contains one to three highly coiled seminiferous tubules in which sperm are produced
B. Each seminiferous tubule is lined on its inside by two types of cells called Leydig cells and Sertoli cells
C. The region outside the seminiferous tubules called interstitial space, contain small blood vessels and male germ cells (spermatogonia) which lead to sperm formation
D. In testis immunologically component cells are also present
E. The seminiferous tubules of the testis open into the rete testis through vasa efferentia

• A. B and C
• B. B and D
• C. D and E
• D. B, C and E

Answer 1

The correct option is D B, C and E

Each seminiferous tubule is lined on its inside by two types of cells called male germ cells and Sertoli cells. Sertoli cells are supporting cells. The male germ cells undergo meiotic divisions which leads to sperm formation. The regions outside the seminiferous tubules called intersititial spaces, contain blood vessels and interstitial cells or Leyding cells. Leyding cells synthesise and secrete testicular hormones called androgens (testosterone). Seminiferous tubules open into vasa efferentia through rete testis.
