Assertion (A) Explanation
The assertion states that Leydig cells are located outside the seminiferous tubules of the testis. This is accurate because:
- Leydig cells, also known as interstitial cells, are found in the interstitial space between the seminiferous tubules.
- They play a crucial role in male reproductive physiology.
Reason (R) Explanation
The reason given is that the testis synthesizes and secretes hormones called androgens. This is also true because:
- Androgens, primarily testosterone, are produced by Leydig cells.
- These hormones are vital for the development of male secondary sexual characteristics and reproductive function.
Connection between Assertion and Reason
- The reason (R) provides a functional context for the assertion (A) by explaining why Leydig cells are important.
- Leydig cells' role in producing androgens is directly linked to their location outside the seminiferous tubules, where they can effectively secrete hormones into the bloodstream.
Conclusion
Since both the assertion and reason are true, and the reason correctly explains the significance of the assertion, the correct choice is:
- a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
This illustrates the interrelationship between the structure and function of Leydig cells in the male reproductive system.

Leydig cells are under the action of ICSH or Interstitial cell-stimulating hormone, which is commonly known as Luteinizing hormone. In males, it is responsible for the growth and development of Leydig cells located in the testes. Leydig cells are located outside the seminiferous tubules which are known as the interstitial spaces. These cells are further responsible for the synthesis and secretion of a class of testicular hormones known as androgens.
