Question

Assertion :The regions outside the seminiferous tubules are called interstitial spaces, which contain Leydig's cell. Reason: Leydig's cells synthesise and secrete testicular hormones called androgens.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion

Each testicular lobule contains one to three highly coiled seminiferous tubules in which sperms are produced. Each seminiferous tubule is lined on its inside by two types of cells called male germ cells (spermatogonia) and Sertoli cells. The male germ cells undergo meiotic divisions finally leading to sperm formation, while Sertoli cells provide nutrition to the germ cells. The regions outside the seminiferous tubules called interstitial spaces contain small blood vessels and interstitial cells or Leydig's cells. Leydig's cells synthesize and secrete testicular hormones called androgens.

So, the correct answer is 'Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion'.
