Question
Explain the internal structure of testis (Figure is not essential).
✓
Answer
→ Each lobule contains one to three highly coiled "seminiferous tubules" in which sperms are produced.
→ Each seminiferous tubules is lined on its inside by two types of cells.
(i) Male germ cells : It is also called Spermatogonia.
→ It undergo meiotic divisions finally leading to sperm formation.
(ii) Sertoli Cells : Provide nutrition to the germ cells.
→ In a lobule the regions outside the seminiferous tubules are called "interstitial spaces".
→ Interstitial spaces contain : (i) Small blood vessels (ii) Interstitial Cells/Leydig Cells
(iii) Other immunologically competent cells
→ Leydig Cells Synthesise and secrete testicular hormones called "androgens".
